How Sleep Apnea Causes Pepsin Reflux

Sleep apnea and acid reflux go hand in hand. An obstruction causes a vacuum effect in the throat, which suctions up your normal stomach juices into your throat, causing more inflammation and swelling, causing more obstruction. If you have large tonsils, it becomes even more enlarged, causing severe breathing problems at night. Not only do the mucous membranes of the throat become swollen, the tongue swells up as well, leaving impressions on the sides of your tongue due to pressing on the teeth.


Most people are aware of acid reflux, but what’s virtually ignored is the fact that your stomach juices contain many other irritating substances, including bile, digestive enzymes, and bacteria. In fact, pepsin, one of the main digestive enzymes, and H. pylori, a common stomach bacteria, are both found in ear, sinus and lungs washings. These are major sources of inflammation and swelling in your upper airway.


A recent study published in Otolaryngology – Head & Neck Surgery showed that deposits of pepsin can linger in the throat, and every time acid comes up, it gets activated in the more acidic, low-pH environment. They cultured throat cells with and without pepsin and measured 84 different inflammatory markers, of which 9 were found to be significantly increased, even in a non-acidic environment. This can potentially explain why people with laryngopharyngeal reflux disease have persistent symptoms despite maximal acid reflux medication therapy. 


Laryngopharyngeal reflux disease is a common condition where small amounts of stomach juices reach the throat. But it’s important to realize that giving acid suppressing medications like Nexium or Prilosec does nothing to prevent reflux. What these medications do is to lower acid production in the stomach so that whatever comes up doesn’t irritate the throat (or esophagus) as much. It’s not surprising that these medications don’t always help.


I think you’ll agree that constantly having small amounts of digestive enzymes in your throat can definitely cause problems. More commonly, people will complain of post-nasal drip, throat clearing, hoarseness, chronic cough, a lump sensation, tightness, burning, usually with no stomach problems whatsoever.


This is why eating early and not snacking before bedtime is so important for people with sleep apnea (and everyone else, too).

  1. Great article! But, does the sleep apnea cause the acid reflux, or amplify it? I have sinus congestion, acid reflux, and recently diagnosed with sleep apnea. My tonsils have “grown back” after 40 years. I can’t get off the Prilosec, but have gotten off one of my high blood pressure medications. Will my acid reflux eventually stop because I’m on a cpap? It’s like hot knives cutting through my throat.

    Thank you,


  2. It doesn’t matter which comes first. Once it starts, it’s a vicious cycle. Treating sleep apnea should help with your laryngopharyngeal reflux disease, but don’t count on curing it completely. You may need to stay on Prilosec for a while until things settle down and then consider tapering off once you feel better. Thanks for commenting.

  3. I was diagnosed with pharyngeal reflux disease almost 4 years ago. I had been to my GP, and allergist when I was sent to an ENT. I had laryngitis for 6 months (no kidding) and it was really tough. I sing, and I am an educator, so I use my voice a lot. The protonix worked really well for about a month, but then symptoms started to return. It is so frustrating…my singing voice and range have been affected most of all. I have real difficulty with the transitions that are right aroune my lift-point (where I change from my “chest voice” to my “head voice”) I don’t know what else to do. I have gone to a new ENT, and he has ordered a video strobe test(?) So, here we go again. Do you have any suggestions?

  4. Robin,

    Your experience is not too surprising. Protonix and other acid relfux medications don’t prevent your stomach juices from reaching your throat. Are you absolutely avoiding eating or drinking alcohol within 3-4 hours of bedtime?

    Do you have any other symptoms of an underlying sleep-breathing disorder such as unrefreshing sleep, not being able to sleep on your back, and maybe even snoring?

    If some of the above problems resonate with you, I recommend that you read my book, Sleep, Interrupted. It describes my sleep-breathing paradigm, and steps you can take from conservative to more aggressive steps.

  5. I have sleep apnea  and acid reflux  and it can be difficult to use machine sometimes I thin k I could use the cpap if i had the reflux under control  but as it stands it hit and miss every night whether I get sleep or not its wearing me down   I have started to use Kangen Water to see if it can help whats u opinion  I would try anything

  6. i recently in nov or so started thinking i had to clear my throat because of allergies which i treated to dry up..then in jan it got worse more stuff in throat to clear and my anxiety started up so i dont know if one fuels the other..i know if im more relaxed the throat wont flare but something is their even with anxiety..ive tried so many natural treatments one by one dont know if there working or not..but ill try anything..i feel a little burning in my stomach here and there but just the do u really treat this..ive checked my ph which was 6 but then 7.5 so is that a true test of really concerned it wont go away..what do i do to fix this? i dont eat wrong foods.drink alcohol or smoke..

  7. I have been dealing with reflux for several years. Constant pain in my throat right side at the top of my collar bone – when I breathe outside in the cold or inhale after chewing a halls I can feel the pain sensation down there. I switched from prilosec to nexium and zantac about a month ago. I have a follow-up visit with my gastroentorologist next week. My wife says I snore very loudly. I also have pain where my left nostril connects to my throat but this has improved greatly.

  8. Paula,

    It doesn’t matter which comes first. Ultimately, it’s a vicious cycle. Reflux from sleep apnea can cause your tonsils to get larger, which causes more sleep apnea. Assuming your CPAP is being used effectively, your throat problems should improve. Good luck.

  9. I am in the same boat as many. I have had reflux for over 4 years, and have now been told I have sleep apnea. I definately feel the 2 conditions make the other worse. I have tried the reflux medications-they dont work for me. I was told my tonsils are large and my tongue sits too high. I have propped up with pillows at night to sleep but think my next step is elevating the head of the bed itself. If that doesnt work I may consider having some of my soft tissue removed. I go home each day at lunch and power nap for 15 minutes just to work an 8 hour shift. yuck . I don’t go out anymore on the weekends because that is my sleep time. My friends make fun of me for “being old and tired. ” Its not funny.

  10. I had a severe bout of acid reflux post surgery a couple of months ago. Then I developed a problem swallowing liquids; they feel like they are going back up through my nose, and my palate feels swollen. My nasal passages/sinuses feel irriated all the time. I had an esophagram a couple of days ago and it showed no abnormality with swallowing. An ENT exam also showed no abnormality, except for some redness. I am on a dose of Zantac at night, which helps the GERD but it’s not gone completely. I need to find out what is causing this as it is very distressing.

  11. Don’t know if its allergies or what I read above, but I am always clearing my throat, possibly due to post nasal drip. I haven’t experienced acid reflux issues at this time. I am in the sleep field, and find this information to be very interesting. Most people that have a sleep study almost always experience gerd.

  12. Just been diagnosed with OSA, i have GERD, constant post nasal drip, tired during the day, cant do anything, no drive for anything, i stopped all activitites, i work eat and sleep thats all, i have no life left, im always miserable and depressed or sad. OSA has taken over my life in a big way, im only surviving due to my wife and daughters otherwise, i would not able to continue living this way. I gather that the CPAP machine is also not great to use, im hoping that the med aid pays for it so i can alteast have a little better quality of life, forking all those thousands is making me feel even worse.

  13. I have been trying to get what I now think is LPR diagnosed for the past 3 months. Originally it started out as a sore spot on my lingual tonsil. I visited 2 ENTs and they kept giving me antibiotics and antihistamines. I began to freak out a bit and thought it might be tongue cancer. After stressing, a few weeks later the dry cough, hoarseness, etc. showed up. I have had these symptoms for about 3 weeks now and after doing my own research I am pretty sure it’s LPR. I am getting an ECG this week to see if there is any structural damage to the Oesophagus.

    Any suggestions for getting rid of the Pepsin? I have read that alkaline water works. I don’t really want to take any meds. I just put myself on a strict diet as well. Suggestions for sleep apnea? I do have a deviated septum. Should I get that surgically fixed?



  14. I am scheduled to go in for a second sinus surgery on Friday. I was told by my ENT that my sinuses are so bad that they are siphoning my stomach acid up into my throat which causes horrible and uncontrollable coughing. I am taking protonix but none of the stomach meds I have taken are helping at all. I have been trying to research this condition online but cannot find anything. What have you heard or know about this specific problem.
    Thank you,

  15. A sleep study has indicated that I have many obstructive episodes but no ‘apnea’ per se. Right now one of the most disturbing symptoms I have is a burning of my tongue & the roof of my mouth. This can occur at anytime of the day, but is most noticeable (& most troubling) upon awakening in the morning (or when lying down to sleep).

    I do not have burning in my throat or in my stomach.
    The sides of my mouth though can also sometimes be affected with this burning sensation. I am wondering whether there are glands that secrete acids in the mouth, I would think so, as part of the normal digestion process. But why would the tongue and roof of mouth be so affected? What might be occuring here?

    MIght there be a anxiety response at play here?. During the day it is more noticeable when I get anxious. Perhaps a anxiety response is happening during sleep in response to obstructive breathing episodes? Is it the case that the body produces & secretes digestive acids when feeling anxious? But that I feel this primarily in my mouth -& not in my stomach, is key. (A associated sx during the day is occassional flushing of my face).

    Any thoughts on this? (My primary question is about the burning sensation on my tongue & roof of mouth that occurs most noticeably during sleep). What might you suggest by way of treatment? Does this sound like it is related to obstructive breathing sleep disorder? Perhaps it is really a anxiety/ digestive issue ?

    Most likely is all part of a inter-related syndrome! as you speak of in your book.

    ps – I use a lot of saline products – nasal gel, saline sprays, also use neti pot. Can all this saline be throwing off my ph balance?

  16. Cindy,

    I can’t officially say without examining you in person, but larynopharyngeal relfux disease can happen without any stomach symptoms. Remember that it’s not just acid, but also bile, digestive enzymes, and bacteria that can go up into the mouth. You can stop breathing 25 times an hour and still not have obstructive sleep apnea, since you need at least 5 apneas per hour on a sleep study to have the diagnosis. Since an apnea or hypopnea must last for more than 10 seconds, having 25, 9-second breathing pauses will give you an official score of 0. This is called upper airway resistance syndrome and is treated the same way as obstructive sleep apnea (CPAP, dental appliances or surgery).

  17. Dear everybody,

    I m an interesting case. I had the operation with Linx, but I still have my symptoms of LPR (cough, lost of appetite, chemical taste in mouth).
    Could somebody say to me if you suffer also from a lost of appetite with LPR? My lost of appetite is strong in the morning and it becomes better during the day. Thanks

  18. Hi Dr. Park,

    What is your take on taking HCL w/ Pepsin as a supplement to help with reflux? I have read that LPR more often occurs when your digestive sytem is lacking in HCL.

  19. Besides the numerous recommendations to reduce acid reflux, what can be done to eliminate the deposits of pepsin in the upper airway, larynx, ear, sinus, etc?

  20. I have been going round and round with one doctor after another. For more then four years I have have ever increasing asthma symptoms. In the beginning I was prescribed Advair which helped at first, but then I started having severe heartburn. Doctors said there was no connection, but at my insistence changed me to Dulera, when I started having blurry vision, and heartburn didn’t get better, either. Again, doctors said no connection; however, it is now listed as a known side effect. My research found as you say here, eating smaller meals etc. help, which they have, but still acid reflux doesn’t go away….

    When I read this report I felt like you were talking about me. I “can’t” sleep on my back, never have been able to. Post nasal drip, clearing my throat, hoarseness and only recently has a slight cough started. there are times when I have trouble swallowing, but that isn’t consistent.

    Here is my question. About the same time the asthma symptoms worsened I started snoring. I snore with my mouth shut which my husband finds amazing. I have tried to tell my doctors that I am sucking acid from my stomach and the only solution they have is medication. right now I am in a cycle being on predisone all the time, which I know isn’t good long term. I finish a dose and within two weeks I am wheezing again. I finished my latest round of predisone and Advair, abuterol inhalers and my nebulizer treatments barely relieve my symptoms….I feel like I am addicted to predisone! Would a dental appliance that would re-position my jaw help? It just seems if there is a vacuum effect there has to be a way to break the vacuum. Should I insisted on seeing an ENT. Could there be an issue with my sinus’ I did insist on a sleep study, but that said no sleep apena, but you said it still could still be an issue…….can you see how confused I am. I don’t want to take life long medication unless there is no other solution, at 62, all this is not good for my bones….HELP!

  21. Ms. Johnston,

    Sorry to hear about your health issues. In general, you can keep going down the path of more and more aggressive treatment options for reflux. Unfortunately, they are likely to fail. What I see quite often is that repeated obstructed breathing that don’t last long enough to be apneas will still suction up your stomach juices into your throat. Even if you don’t have sleep apnea, it has to be treated like sleep apnea. Unfortunately, sleep physicians won’t treat you unless you have a sleep apnea diagnosis. However, CPAP and oral appliances can still be used. Good luck.

  22. I theorise that I have swollen nasal turbinates for two reasons. One is that OTC Oxymetazoline helps me temporarily when things like anti-allergy meds and Vics Vapour Rub do not. The other is that when I was tested for LPR reflux, a tube was put up my nose. When it was, my symptoms subsided for a whole 24 hours, and returned when the tube was removed. For the record, all reflux meds I’ve tried, including PPIs, Alkaline Water, Gaviscon Advance and even antidepressants have failed me.

    Swollen turbinates caused obstructed/unusual breathing. Unusual breathing causes some mild sleep apnae (I’ve woken up gasping a number of times) and can cause this vacuum effect both in the day and at night, leading to pepsin being detected. This is why I’m getting small amounts of reflux detected in my saliva, even though my dual-impedance studies say my reflux levels are normal, despite me binging on junk foods.

    Does that sound like a reasonable theory? Do you think if I treated my turbinate swelling, my reflux symptoms would stop?

  23. Why is it so difficult to diagnose and treat Acid Reflux Symptoms? I too suffer albeit not has badly as some. I also have Sleep Apnea. I can’t get use to the CPAP. I used it last night and I awoke with severe heartburn. I haven’t had a severe episode in weeks. Ironically, I haven’t used the CPAP in weeks. So, I’m thinking my CPAP caused last night’s episode. I too am interested in the HCL with Pepsin. I am currently taking Lansoprazole DR 30 mg. I also started taking a probiotic. I’m thinking of seeing a Naturalist but I just don’t know what to believe and I don’t want to spend a ton of money. I just wish i could receive a more coordinated effort from my PCP. It just seems she wants to push the meds which would be fine if they worked.

    Any suggestions?

  24. Bill,

    While CPAP helps millions of sleep apnea sufferers, sometimes, it can also cause more problems than it helps. And just because you’re using CPAP doesn’t mean that it’s working effectively. Treating reflux in general should help with sleep apnea, but it’s not always consistent. Unfortunately, PPIs like what you’re taking doesn’t treat reflux. It only lowers acid secretion.

  25. I’ve been treated for LPR for about 10 years and take 40 mg of Protonix daily. My reflux is better now that I’ve eliminated wheat, gluten, grain and dairy from my diet. In fact, I feel changing my diet has done more than the PPI. Occasionally I experience a sore and swollen tongue (teeth marks on both sides), which causes loud snoring at night. Recently my mouth started burning in addition to having a swollen tongue. There must be a way to prevent stomach acid from reaching the throat, mouth, sinuses and ears. I’ve lost weight and have changed my diet. There must be something else I can change to reverse or stop this disease instead of reacting to its symptoms. Any suggestions?

  26. IG,

    Please take some time to go through some of the basic articles on obstructive sleep apnea and upper airway resistance syndrome. My basic premise is that due to repeated breathing obstructions during sleep, many people vacuum up normal stomach juices into the throat.

  27. I have learn so much today because I had been suffering from these GRED and esophageal disease for the past 4 years now and this days I had been experiencing mucous coming out from my throat especially at night. I will be grateful if you will be sending me your latest articles thank you so much.

  28. Though I have sleep apnea, after a tuck & roll I’ve got Gastroparesis causing LPR – EER into my sinuses. Protonix 40 mg X 2, chewing erythromycin before meals, and lots of nasal rinse help. Any other thoughts Dr.? How about Chinese medicine, or acupuncture, or reflexology?

  29. i am awakening every morning with a pain between my breasts that comes on strong then subsides and leaves a burning in my used to go away but now i have the burning and excessive gas all day.i also get a numbness going down my arms that quickly subsides i just had a sress test that came out fine.i also use a c-pap machine for about a year. but i have had this problem longer than that.have seen several gastro doctors with no solution

  30. Dr. Park, Can you please answer the question about taking HCL with pepsin with meals? I have LPR but probably don’t have sleep apnea. I have a congenital deformity in my lower jaw that is set way back, giving me a big overbite. As I aged, I had more and more problems with LPR, but doctors kept misdiagnosing it as allergy rhinitis. Now I know what it is, but the ENT’s here won’t believe me. I am in the process of trying to get fitted for a CPAP machine which I know will not bother me because I already sleep with large nasal dilators. When I tried PPI’s, they had absolutely no effect on my LPR and bothered my stomach (probably because digesting your food without stomach acid can bother your stomach, DUH!!)

    Anyway, I have had some relief from taking HCL with pepsin and bitters during a large meal. It seems to get my meals digested faster and cuts down on indigestion.

    Do you think a CPAP would work for me – I am so tired of the sore throats and nasal congestion in the morning!

  31. Also, Dr. Park, I purchased and read your book. My husband is a retired physician and he thinks you are really on to something about the stomach acid being sucked up into the throat. I felt like you were talking about me when you said in the book that LPR is more likely to happen during REM sleep. Often, if I don’t sleep deeply, I don’t get the LPR. But when I am really tired and sleep deeply, I get it almost every time. There is definitely a connection, in my case, between REM sleep and LPR.

  32. Ms. Fister,

    Thanks for sharing. The only way to know if CPAP will work is to try it. It can’t hurt. In general, people with small jaws tend to have more obstructed breathing, which can aggravate reflux.

  33. I am 32 years old guy. My life went very happy without thinking of food & lifestyle. Any time I will eat without limit, anytime I will drink and anytime I will sleep without thinking of anything. Life went very well without illness. Few months back continuously 20 days i suffered with throat pain and irritation. My voice changed totally but I never took it as serious issue. One day after dinner I went to bed lay-down and started to watching the TV. Suddenly I got huge cough in that time my breath and voice was stopped. I thought I am going to die and try to recover my breath and voice after long struggle few mins back I came to normal. Immediately I went to hospital they took me to ECG, Blood, chest/lungs x-ray and nasal endoscope. Doctor told me that due to throat infection it was happened and gave some tablets. I returned happily to home since I thought there is no major problem. After two days back while sleeping on night time i got same breathing stuck issue and struggled. I put my fingers on my mouth and try to take vomit and recover my breath. It took very long to recover again by releasing some air by mouth. I went to may hospitals and took various tests but no use. My breathing issue started to come regularly. I started to fear lot and thought I am going to die soon. Since it is suddenly coming in night time in between sleep I can’t imagine or explain by words. After long struggle I met on doctor he told me that it may due to acid reflux problem and took endocopy. Results shown as Lax LES on OG junction. Doctor gave me few antacids to reduce acid. But still my throat pain, cough and breathing issue not recovered. Finally I met one doctor he also gave some medicine to reduce stomach acid and getting positive reply. I recovering slowly. Now night time breathing attack fully stopped but sometimes getting cough and making me wakeup. Due to fear or some stomach issue my food intake got reduced lot and my weight got reduced 11kg in 4 months. Doctor reduced step by step in dosage. Currently only night time I am taking antacids tablet before food. I have lot of work stress, pressure, sudden angry type of character. Still I am facing little bit of throat issue, body pain, fear and night time cough. Can anyone help me on right remedy, treatment or medicine to fully recover from this issue.

  34. I don’t know if I have sleep apnea, as I have never been tested. However, the symptoms I am having led me to this website and I am desperate!

    I have always been very mucous-y, and I constantly have the need to clear my throat. Rarely have had traditional “heartburn” or gastric reflux symptoms though. I frequently have felt like food has gotten stuck in my throat. My whole life I just assumed I had a small throat passage. I have in the past had issues of waking up very hoarse.

    I have had occasional issues with “lingual tonsillitis” about 2 times a year for the past 3-4 years. I would start with a very sore throat very far back, and finally my local ENT scoped me and found it was the lingual tonsils causing the pain. (My regular doctor never saw anything on routine throat inspection). I would normally take a round of antibiotics and a steroid dose pack and have relief within a couple of weeks.

    On September 11 of this year, I woke up with that familiar throat pain. I suffered through it a week or so, and it got completely unbearable. It started feeling like my throat was swelling shut. I started having panic attacks. Trouble swallowing. I went and saw my ENT after a week or 2 and got scoped. It was my lingual tonsils again, and he said they were “huge.” So I got strong antibiotics (Clindamycin) and prednisone. Took them both 10 days and had zero relief. I had panic attacks daily. Slept sitting up, or else it felt like my throat was literally closing up. Swallowing became a chore. I had to request the doc to call in something for my nerves and panic attacks.

    I decided to make an appointment in Birmingham, where they see more complicated issues. I saw a new ENT at the end of September. His office scoped me and found that my right lingual tonsil was indeed very enlarged. The left side was fine. The doc was worried since the swelling was so bad on one side, that he immediately scheduled me for a biopsy and then surgical removal. I started Nexium once daily at that point.

    I had the biopsy October 22nd, and it was benign (Thank you, Lord!) So he was able to burn out the area with a laser. The next few days were relatively easy. I had minimal pain. Still some difficulty swallowing and feeling like there was something stuck in my throat. I convinced myself that it was postoperative swelling and it would get better. At least it wasn’t cancer, right?

    Fast forward to now. I STILL feel like my throat is sticking together on the right side, and still feels like there is a huge lump back there. I went back for an early postop appointment yesterday and got scoped again. Doc said everything was nearly healed, much to his surprise, and it looked better than he expected it. That’s good news, I know. But it doesn’t explain why I still feel like there is something stuck back there, and swallowing is so difficult.

    I’m so depressed about this, I can’t stand it. The doctor seems to think I may have some silent reflux (LPR), so I am increasing Nexium twice a day. He said to give it about 3 months and come back for another scope to see if it’s helping. THREE MONTHS?? I am completely miserable! This is ruining my life! I have 6 kids, and 2 jobs. I don’t have time to feel so awful! And from what I read, the Nexium isn’t really going to stop the issue of the reflux, just the acid level. I realize that people have non-acidic reflux as well. Where do I turn now? What tests do I need? What treatments are even available?

    I live in Alabama.

  35. I have been diagnosed with sleep apnea for over eight years–originally it was classed as “mild”, but I was placed on CPAP therapy. Unfortunately, I had significant difficulties adjusting to the machine and found it was impossible to ever get to sleep. I am disabled and have chronic pain in my lumbar region and legs, so I must turn regularly in bed at night to seek relief from the pain. When attempting to use CPAP this would often cause the air hose to pull out of the machine and I’d end up with water in my nose/lungs. So after a month I threw in the towel and discontinued therapy.

    Now 8 years later my sleep deprivation problems (which include extreme nighttime urinary frequency–contributing further to breaking my sleep by making me have to get up every hour or less all night long) are much worse. They were a significant factor in my having to take early retirement on disability (I had worked full-time for 15 years after being in a wheelchair due to orthopedic & spinal degeneration). I’m currently diagnosed after a home sleep test (AHI 22.1) with “moderate to severe” apnea. So I began a second round of CPAP with a new more sophisticated machine. However, my experience with it went no better–in fact it was worse.

    I was determined this time to succeed and be totally compliant so I could improve my sleep quality and overall health. But 10 days into therapy, I developed a chronic sore throat, began to have continuous sinus drainage/sinus headache, which created lung congestion and asthmatic wheezing. It got bad enough that I spent most of my time in bed. I tried to adjust the humidity and heat settings which online articles had suggested as possible solutions to my sinus issues. But nothing helped. Finally, one night the machine made scary noises and began spewing large water droplets into my mask/face, what I’ve learned since is called CPAP rainout. That negative experience on top of feeling so sick for 39 out of the 49 days I had faithfully used the machine made me discontinue therapy and return the machine to the distributor.

    Two weeks later I went to an ENT specialist because although the sinus/lung/asthma issues had improved immediately upon discontinuing CPAP, the sore throat had not. I had tried 2 antibiotics to make sure it wasn’t infection, but they were both completely ineffective. So the ENT diagnosis was acid reflux and I’m now on generic Zantac and Prilosec. Neither seems to be helping, nor is diet adjustment (removing acidic or acid promoting food/drink, eating smaller meals, finishing eating at least 3 hrs before bedtime, etc).

    My disability/chronic pain is hard enough to deal with and I must do a regular exercise program (lap swimming) to maintain muscle and cardiovascular health. CPAP made me so sick I had to stay out of the pool for two months and ended up in bed all the time. That’s no quality of life! But I know CPAP is probably the best treatment for the apnea. If I could only discover the way to negate these side effects, I could resume CPAP and continue to try to deal with the acid reflux with diet and meds. After researching online, I find many articles that link apnea and acid reflux but it is unclear whether one causes the other or they simply appear together. Although I’ve had apnea for years, I had no indication of reflux until my recent CPAP experience.

    Alternatives to CPAP seem unlikely for me (the ENT dr said she felt the oral apnea device would be useless for me and surgery not called for), Don’t know what to do now.

  36. Very useful and informative article on sleep apnea and Pepsin Reflux.
    I have experienced constant throat clearing, hoarseness (especially later in the day) and post nasal drip for 40 years. I rarely rexperience heartburn, but have been diagnosed with GERD and mild obstructive sleep apnea. Results of using a BRAVO capsule showed no episodes of acid reflux with normal pH readings for the test interval of 24 hours. Recent endoscopys showed the beginnings of Barretts Esophagus. Also, I have a normal BMI at 5″ 8.5″ and 150 lbs.
    By changing my sleeping position to stomach only and using a AirSense 10 CPAP, my obstructive apneas have dropped to zero, and AHI fallen to less than 1 most nights. Initially, the Total Time in Apnea was as high as 1 hour and 52 minutes per night; that’s a lot of time not breathing!! Now I rarely exceed 60 seconds of not breathing per night due to hypopneas. Although sleep is greatly improved, I have noticed mild GERD when I awaken for no apparent reason. This occurs in spite of no food or drink after 4:00 pm in the afternoon.
    Your article sounded alarm bells as I have been taking a Betaine HCl + Pepsin supplement with meals because I produce little stomach acid. Would you recommend stopping this supplement?

  37. I am always super tired, nautious, weak & have no energy during the day & my sto.ACH : throat feel swollen & hurt.

  38. I’ve had surgery to reduce a turbinate in my right nostril last November, after having been to an ENT on numerous occasions and they stated I had allergies ( I personally dont think I suffer from allergies, no runny nose or sneezing). I have suffered from constant blocked ears for 1.5 years now, constant mucus in the back of my throat, voice is getting hoarse (non smoker), when I blow my nose to try and unblock. I never feel refreshed after a nights sleep and I get between 7 to 9 hours. My ENT checked my ears and said there was nothing wrong with them. After reading your articles above, I’m so relieved to pinpoint what I know I have. I know I do have sleep apnea and my snoring has gotten worse due to my blocked nose. My question is would you be able to tell from ear pressure tests and exam – just looking into the ears if they have been affected from stomach acid? I’m due back to the ENT next week and I want to ensure that my info is correct, as every time he looks into my ears, he says he cannot see anything wrong with them.

    I would really appreciate your answer and I’m grateful that finally – from your above writings on sleep apnea and its vacuum effect on ears, stuffy nose and mucus, I now know that I can finally get this resolved. I need to find an ENT that will listen and not brush it off as allergies.

  39. Good evening!
    Dr. I wish you could help me. I live in Brazil and read his articles on laryngopharyngeal reflux and sleep apnea. I have been suffering for a year now, I have to clear my throat constantly, I have a chronic cough, and throat throat, like a closed throat sensation. I underwent several exams, endoscopy, pHmetry, manometry, esophagus scintigraphy, tomography of the face and X-ray of the lung. In these examinations were found: in the small endoscopy edema in the esophagus, I do not have HP bacteria in the stomach, the pHmetry presented acid reflux and the manometry the inferior valve of the stomach is with 7 mmHg of pressure, perfect X-ray and tomography of the face presented discrete sinusitis that Was treated with antibiotic avalox, whereas the acid reflux treated with Nexium 80 mg and motilium 30 mg per day for 3 months and for a month I am with 40 mg of Nexium and 20 mg of motilium. Nothing solved, I have been suffering for a year. During the night I snore and sometimes I have night sweats. On December 21st I will do polysomnography. I have seen in one of your articles that pepsin (an enzyme in the stomach) can cause these problems. Being that Nexium and Motilium just would not solve. Please could you tell me what I could do to relieve these throat throat symptoms, I am a chemistry teacher and I can not bear to talk to this frequent throat cleansing symptom. Thank you very much. I await your reply. Kind regards. Cassia

  40. Cassia,

    Sorry to hear. I can’t give you any medical advice without examining you, but in general, your symptoms sound like obstructive sleep apnea with reflux. Let’s see what happens once you undergo your sleep study with treatment for sleep apnea. Good luck!

  41. Hello doc,

    Im a 35 year old female. Not overweight and pretty active. Last year I was diagnosed with sleep apnea after telling my doctors I was chronically tired for the last year. Finally they did a sleep study and diagnosed mild sleep apnea. The last 3 years I have been getting loads of sinus infections and this feeling that I can’t breath in the mornings when I wake up. My Ent and doctor are pretty convinced I have Silent reflux, and I’m allergic to dust. My allergist thinks my allergies as well as the Silent reflux is causing intermittent asthma. They started me on qvar twice a day, prilosec 20mg 2 times a day and zantac at night. My question is that can Silent reflux really cause all this? Since starting this regimen a last week I do see a slight improvement but hate taking all this stuff…. Feeling like a pharmacy. Lol

  42. Joy,

    Taking acid reducing medications is the standard of care in the ENT field, but it does nothing for reflux. You still have less acidic gastric contents coming up and bathing your sinuses and lungs. The best way of addressing this issue to to treat the sleep apnea aggressively, no matter how mild it is. Good luck.

  43. Having been diagnosed with mild sleep apnea 8 years ago, only recently have I discovered that I have LPR and this does not play well with good quality sleep. If you are using a CPAP with a data card that can be removed and read by your PC/Laptop, look at SleepyHead software which will allow you to see a second by second, breath by breath record of your night’s sleep. SleepyHead logs lots of sleep parameters, and then plots them in graphs which follow your entire night’s sleep. My respiration rate showed I was hyperventillating in the periods ( sometimes hours) before I woke up during the night. Since I have mild asthma and also use a QVar inhaler, the shortness of breath was attributed to asthma. However, using a small SpiroFlow ( home spirometer ) I test in the normal range right after waking up. Upon doing some research, hyperventilation causes rapid loss of CO2 and an increase in the pH (more alkaline) of blood. Now the oxygen binds more tightly to hemoglobin, and does not release it as readily to the tissues. Continued hyperventilation causes lowering oxygen levels and one could wake up short of breath. There is much in the literature on this topic, and it is worth looking at. The use of SleepyHead software to look at your nightly CPAP breathing data may help to identify the cause of your problems. It was an eye opener for me, and now my AHI is almost always less than 1 with no obstructive apneas. Feeling well rested, however, does not correlate with low AHI as other factors are at play. Good luck with analysing your CPAP data and improving the quality of your sleep.
