Can Sleep Apnea Cause Hiatal Hernias?

Someone emailed me in response to my comment that hiatal hernias may be related to sleep apnea. He basically said that my ideas were nonsense. Here’s what I wrote back:

“Thanks for taking time to comment. I did mention that it’s a hypothesis, and yet to be proven. In my opinion, a hiatal hernia is similar to having a deviated nasal septum. Everyone has some degree of it (due to jaw narrowing and dental crowding), but only some people have symptoms. One thing I’m learning as I study the effects of sleep apnea is that it can cause or aggravate almost every chronic medical condition that we know of, from a metabolic, hormonal, neurologic and immunologic standpoint. I know about the classic medical explanations of hiatal hernia as well as many of the alternative/complementary explanations. But I don’t find any of these explanations satisfying. If you look at all the various studies on the effects of sleep apnea (which is due to a craniofacial underdevelopment of the jaws that most modern humans have, that leads to crowding of the upper airway), it was only logical that sleep apnea (which is so common and undiagnosed) may lead to a hiatal hernia.

For example, pressure readings using catheters in the esophagus during apneic episodes show tremendous negative pressures in the chest cavity, with loosening of the phreno-esophageal ligament, which opens up the lower esophageal sphincter temporarily. These pressures are also strong enough to prevent blood flow to the heart during these episodes. The junction of the stomach and the lower esophagus (the lower esophageal sphincter) sits in an opening in the diaphragm, like a sleeve. If you’re pulling down on the diaphragm with excessive positive abdominal pressure, while creating tremendous negative pressure in the chest cavity, along with loosening of the phreno-esophageal sphincter, it’s plausible that the lower part of the stomach can slide up into the chest cavity. Continued vacuum effects in the throat, along with upper and lower esophageal sphincter dysmotility, can lead to pharyngeal reflux, which has been shown to reach the lungs, sinuses and ears. This also includes digestive enzymes, bile, and H. pylori.

Lack or oxygen to the brain and the body, as well as a massive physiologic stress response, can alter your involuntary nervous system, creating a relative overactivation of your sympathetic nervous system (increased adrenaline), and an underfunctioning parasympathetic nervous system (vagus nerve).

Sleep apnea is only a small aspect of my sleep-breathing paradigm, which states that all modern humans stop breathing occasionally, due to various factors. Even healthy people can stop breathing during a simple cold. Thin, young people can stop breathing 20 to 30 times per hour and not have official sleep apnea on a sleep study. It’s taken for granted that most people breathe properly at night, but this is absolutely not true—due to our ability to talk/communicate, as well as a shrinking of our facial skeletons. Looking at health and disease from this perspective, it goes against most traditional dogma, whether within allopathic medicine or alternative/complementary fields.

When I was a medical student, my mentors at Columbia University were laughing at the hypothesis that a simple bacteria could cause stomach ulcers. The person that proposed this hypothesis went on to receive the Nobel Prize in medicine. I’m not saying that my research is of that magnitude, but we have to be willing to think outside the box if we’re going to make any significant progress.”

What do you think about my hypothesis?

  1. My dad had severe untreated sleep apnea. He had congestive heart failure, stroke, hiatal hernia, frequent trips to the bathroom at night. He had all of the classic symptoms that Dr. Park has described. It is no coincidence that his sleep apnea caused these illnesses.

    Sleep apnea runs rampant in my family. Our family has small jaws and/or recessed chins. Most of my family members have high blood pressure, heart disease; some have diabetes; some have had kidney stones; most have been treated for depression and anxiety. It’s all that Dr. Park has written. Thank you, Dr. Park for your dedication. It’s a relief to know what the cause of my family’s illnesses are.

  2. Thank you for your suggestions.

    I think that you are 100% right.

    I have quite a large hiatus hernia and severe sleep apnoea. I have 54 apnoeas an hour.
    If I sleep with the CPAP machine my stomach is pumped with air until I wake up on pain. So much that I started been concern that might hurt me badly. I think that because I have the stomach hernia all air go straight to the stomach…

    But but if I do not use the CPAP machine I am a living ZOMBIE.

    So not mater what I do I am screw… I am only 33 and I cant believe that I have to live like this all my life.

    Doctors say that surgery for sleep apnoea doesn’t work. Therefore there isnt nothing they can do… I am in the waiting list to have the hernia put back in place… but ho knows when..

    Any suggestions? Please help

  3. I think you’re on to something. I’ve been complaining of abdominal pain for 6 years and been diagnosed with everything from IBS to fibromyalgia. I’ve even told doctors I’ve felt a bulge in my stomach and been ignored. Now after years of having my complaints swept under the rug and treated like I was seeking drugs for pains that are “in my head” my inguinal hernia has been discovered. My sleep apnea started mild and in the 1 year became severe.

    I fully believe all my medical issues are from this untreated hernia. I believe there is a connection to fibromyalgia and hernias in women. I understand hernias are hard to diagnose in women, but doctors who don’t care to think outside the box shouldn’t put people in them.

  4. I could not agree more and wonder why more people don’t come to the same conclusion. I was a very healthy 37 year old male. 190 lbs and 6ft 2 in. slim and athletic. very healthy throughout my life. I was diagnosed with severe obstructive sleep apnea due to recessed jaw, wide tongue at base and relaxed palate. I suffered near 60 episodes per hour. I also began suffering from GERD (badly) and at the same time was diagnosed with a hiatal hernia (sliding) that seems to create some major issues for me. Chest pain, trouble swallowing, vagal nerve issues (mayo diagnosed me with minor vasal vagal insufficiency). These all started near the same time and in the same areas of the body. I now have been diagnosed with graves disease (hyper-thyroid) which is an auto-immune disease. I often read about people who have these types of ailments together. I doubt it is coincidental and even common sense would tell you that they would affect one another. THE MILLION DOLLAR QUESTION…if your hypothesis is true, what do you do about to get your life back?

  5. Hi all,
    great article, thanks for it. I suffered with hiatus hernia for 12 years and along this time sleep apnea was diagnosed as well. Like Jose, without CPAP I am living zombie.
    Now it’s 4th day after my operational treatmet of hernia (fundoplication) and I have to say that heartburn disapperaed as expected but extreme fatigue disappeared as well. I stopped using CPAP about a year ago and suddenly I feel much better. Does it mean that there can be any coherency between hernia and apnea?

    Many thanks for reply.


  6. Martin,

    OSA and GERD can aggravate each other. It’s a vicious cycle. Once your GERD and hiatal hernia was treated, it lessened inflammation in your throat, lessening your sleep apnea. Even if you do feel better, it’s important to undergo a sleep study again to make sure your OSA is significantly improved. If it’s still there, your chances of GERD and hiatal hernia recurrence may be higher.

  7. Dr Park, Its 3:00 in the morning, and after awakening in bed several minutes ago with a gasp for breath, it ocurred to me to ask this very same question. I’m a 64 year old white male who has a very large hiatal hernia for several years now, and have even been hospitalized for observation for a couple of days because this hiatal hernia caused symptoms that mimiced a heart attack, ie, pressure on my chest, shortness of breath, etc. I sleep with the upper 1/3rd of my matress blocked up at about a 30 degree angle similar fashion to a hospital bed to help deal with GERD that I’ve had in the past. For the last couple of weeks I’ve awakened several times gasping because I have seemed to stop breathing in my sleep. I’ve also noted from these incidents that they seem to ocurr at times when I’ve foolishly eaten 3 to 4 hours prior to bedtime, and wondered if pressure caused from aggravating this hiatal hernia condition could be causing me to cease breathing while asleep. I’ve also had a non stop nasal drip that you’ve described, but have had that all my life and assume it’s from allergies. I am somewhat of a shallow breather, however I was recently briefly hospitalized for an atrail fib episode, and my oxygen levels were running 94% to 96% even at night when they checked me. I think it’s entirely feasable that my hiatal problem could be triggering these aphnea episodes, whats your opinion?

  8. Doug,

    You’re describing classic obstructive sleep apnea. Even a-fib has been linked to obstructive sleep apnea. You should consider seeing your doctor about getting tested for obstructive sleep apnea.

  9. Hello Dr. Park,
    I am a 44 year old whit female. I have sleep apnea and yesterday was diagnosed with a slidding hiatal hernia. I have had acid reflux for years. I also suffer from poor digestion, my bones hurting, memory loss even mid sentence, recently I see light and dark shaded diamond shapes in my full vision for which I saw 3 specialsits and they say may eyes are fine. I have many more symtoms along that I wont list at this time. I also had a blood calcium level come back at 11.2 but when I stopped taking supplements it came back in the 9.9 so they dismissed hyperparathyroid disease. I am convinced that all my symptoms are related in some way. Somthing is causing these things to happen and they cant find it. I definetly believe that you cannot have this many different things happen to you and they arent related. Now they are trying to convince me that these things are happening because Im depressed. Ive never been depressed in my life, although I do take Lexapro for anxiety. Only because I get a fluttering in my stomach that they say must be anxiety. Why dont they put all this together and how can I convince them Im not depressed? Im at my breaking point after 15 years of un diagnosed sleep apnea, I feel like an 85 year old lady. Any suggestions? Help!

  10. Hi Dr.Park

    This is certainly an interesting topic. I tend to agree with your views. I’m 39 and unfortunately am morbidly obese 8-(. I know my mistake. Am currently awaiting barriatric surgery but sm having similar issues with breathing and sleep apnea. I am current just commenced cpap therapy but am yet to see results. It is only 5wks since I commenced therapy so it is still early. I am also awaiting a scope for my stomach as I too suspect a hernia or ulcer. I have Many bad days where I struggle to breath. Heart tests ECG’s, X-rays, lung function tests have all come back good. I’m lucky so far to dodge so many bullets that I suspect may have my name on it. Unfortunately the hospital where I live dismiss slot of my symptoms as anxiety. I acknowledge many of our symptoms can be linked to anxiety but I have never considered myself an anxious person like I’m sure many others claim not to be as well. It seems to be the way with 21st century medicine to think only in black n white. They do not think laterally. Where are all the Dr. Doogey Howsers (prob spelt wrong)?

    There a days I feel like I’m going to die. I only hope the upcoming tests reveal some results. But I agree with you Dr.Park. I’m sur there is a link, and if not, bravo to you for Atleast being open minded to investigate possible links and causes to conditions that are currently not considered possible. Good luck to everyone on here with your health. Will keep you updated on my progress. Cheers from Australia.


  11. Dr. Park,

    What treatments do you recommend for people who have OSA and hiatal hernia and find CPAP aggravates the hiatal hernia too much to continue using it?


  12. Is it possible that a hiatal hernia causes impingement of the vagus nerve which in turn leads to sleep apnea? I have tried CPAP. nasal surgery, and mandibular advancement device with no success. Rather that thinking the the apnea is the driver what if its really the impairment of the vagus nerve by the hernia.
    Any thoughts??

  13. Hello Dr. Park, I’m following up on my previous question and was hoping you can answer it?

    What treatments do you recommend for people who have OSA and hiatal hernia and find CPAP aggravates the hiatal hernia too much to continue using it?

    Thank You,

  14. Doug,

    There’s no specific research that can answer your specific question, but the same algorithms apply: BIPAP, dental appliances and surgery. Some people end up undergoing reflux surgery. There are so many other options that can’t be listed here. Ultimately, it’s a customized approach, based on your unique situation.

  15. Thank you for responding.

    My hiatal hernia is under control with a good diet and only intermittent use of OTC medication and my sleep apnea does not occur when I sleep on my side. Both conditions worsen when my asthma is not well controlled. I ask because I tried the CPAP during my visit to the sleep lab and it immediately aggravated my hernia.

    I will look into the dental appliances.


  16. This all sounds too familiar. About 7 years ago I was diagnosed with Barrett’s syndrome which is precancerous cells on your esophagus. I did not want to take Prevacid as I had read about the side effects so I changed my diet. But then I started to develop sleep apnea. Recently I felt a sharp pain under my left breast and thought I was having a heart attack. Today I had a heart untrasound and my heart is fine.
    The next thing I am having done is to have a sleep study. I feel that pressure is a hiadal hernia but I think it was brought on from not getting a cpap sooner although many of these blogs are saying the cpap aggravates the hernia.
    We sure need God’s kingdom now but until then…… suffering is tough!!!

  17. I like your hypothesis and I hope it’s true.
    Because then I can stop blaming myself for having
    a hiatal hernia and sleep apnea. Eg. “If only I wasn’t so
    anxious then I wouldn’t have given myself this
    hernia which has caused me to have sleep apnea. Maybe
    if I was smart enough I could overcome this anxiety
    disorder and stop making myself sick.”
    If your hypothesis is true then my underdeveloped lower jaw
    caused sleep apnea and anxiety and then came the hernia.
    Ahhhh…yes I like that much better. :)

  18. Hi, I am older female, with long undiagnosed sleep apnea. I noted that when i started with cpap machine, i developed a bump in my stomach and thought maybe it was from air being pushed into my stomach, by the machine.

    I was told it was just weak muscles, even though it kept getting bigger. Turns out the sleep doctor did do a hernia test back then and i had a small sliding hiatal hernia, but what size it is now is anyone’s guess.

    I now have a HUGE ventral hernia, that includes my stomach and part of intestine but no evidence of obstruction but terribly pronounced, to deformity i cannot even hide with clothes. as well as feeling like my stomach will fly across the room if i sneeze.

    no one seems to want to help me, they tell me i need to lose weight, but concurrently i developed terrible problems with low thyroid and digestive issues, with nature thyroid.

    i read it floats around and is never really metabolized, but am not on new drug calld tyrosinct, i hope will work, It is impossible to lose weight with low thyroid and i also had low ferritin.

    stuff just goes on and on. Now with my stomach hanging out of hernia, a gastroenterologist now says, i should look into bariatric surgery, to lose weight so i can repair the ventral hernia.

    i am 260 about and 5’5, but had no problems losing weight until sleep apnea and cpap machine. One month i put on 30 pounds, and did not even come close to consuming that many calories.

    What type of specialist should i go to now? I am in RHode island, but it seems that no one will give any answers or want to treat me, as afraid of the apnea and the hernia.

    Also, i find that the sleep doctors here, have huges incentives to not divulge problems with sleep apnea therapies, because they have rushed to invest in sleep labs ,

    I need a new sleep apnea doctor and someone to figure out things going on with my hernias, and so forth. Sometimes my stomach is so hard like a basketball, and i think it is entirely filled with air. and pushing it self out through weak abdominal hernia of originally tiny proportion. have an umbilical hernia also, as well as a hiatal hernia.

  19. saw sleep doctor recently and he acted surprised by size of my ventral hernia although i pointed it out often on visits, to quite a few doctors, as to what and why was it happening. He also acted entirely in the dark about any hernia/cpap connections, and when i inquired of bi pap his only remark was he liked cpap. This hernia ia now huge, and i am looking into fixing it, but am afraid same forces from cpap will conspire to ruin surgery. needing a re-do Any studies on this stuff anywhere to read?

  20. Hello. Thanks for the article. Though too technical for a non medic expert, like myself, I am SURE hernia is related to Apnea. I never had apnea before and not sure if this that I am telling is . For two / three years I ve had hernia + GERD. I am suffering from occasional and mild apnea( ? )symptoms. Never had before. So far only once i had to wake up grasping for a breath; very unsettling . But what is happening a bit more often now is that as I am falling asleep and my body relaxes I can feel like a Hiccup, like a small palpitation or ventilation around the area where the hernia is suppose to be. So , as I am falling asleep this ” thing” disrupts the commencement of sleeping process wakes me up. I am not sating thats apnea. I am not a Doc. I am saying, trying to listen to my body, that it looks to me that somehow the relaxation of the hiatus sphincter (?) relates to your breathing pattern.Thank you.

  21. Sorry Steven, forgot to say what i was going to say: could it be the other way around to what i understand some(?) have been saying here ? Could it be that hernia is causing Apnea, not the other way around. ( maybe you have said it already and i may have missunderstood/ missed it. English not my first language) . Thanks Steven. Gon.

  22. I have had TMJ surgery, a few years after that I was diagnosed with a hiatal hernia. Fast forward 25-30 years with a diagnosis of Chiari also, and I had a CPAP sleep study last night. Upon waking and sitting on the side of the bed, my left side was uncomfortable almost to the pont of pain. After I walked to my car I realized it was gas but the hiatal hernia kicked in and it’s still bothering me. GERD is worse too. I am definitely with you on this.

  23. I have no doubt that some variants of the hiatal hernia effect nightime breathing. The proof is if you don’t eat at night you breathe better. Along with the theory presented by this article I will add another rather obvious but overlooked explanation to the discomforts associated with this problem. The herniated orifice still attemps to obey automatic closure during digestion. It is part of a normal digestion process. Those of us with hiatal hernias can almost all attest to strange sensations. I believe one of those is involuntary spasms as the orifice attemps but fails to close

  24. I think your hypothesis can lead to significant progress in both hernia hiatal treatment and apnea field. I suffer uars and i was diagnosed with a little hiatal hernia a few years ago. Reading articles on the topic , and especially yours, i have a more global approach of my sleep troubles. According to me, global approach is the best angle to overcome an issue. Some specialists are deeply attached to their appropriate field and sometimes have difficulties to expand their field of vision.
    Thanks for sharing these very relevant hypothesis that make medecine advance.
    I’m french and i’m currently fighting to find a sepcialist of UARS with this kind of global approach.
    Thanks again.

  25. I was diagnosed with severe sleep apnea, over 60 stoppages an hour about 5 years ago. I always sleep with the C-pak as it was so bad I couldn’t stay awake to have conversations or drive for more than 5 minutes. I now realize that around the same time I started to have such severe heartburn every time I ate anything it felt like I was having a heart attack. The GI who did the endoscopy wouldn’t give me any information but I knew it was a hiatal hernia before it was done. I’ve had to take omneprazole daily for 5-6 years. Now I am realizing that I have had multiple symtoms pointing to a goiter. This all must logically be related.

  26. I have been thinking this for some time just due to the proximity in the body between all 3 problems. I have no idea which came first or what caused each. I am 60 now and have gained weight even though I don’t eat much ever since I was about 50. Thus one of my many Thyroid symptoms. Plus I am now having extreme exhaustion and overheating with excessive sweat attacks a few times a day despite being over menopause for about 8 years. I have always struggled with depression and anxiety issues. Also 20 years with 72 hour migraines around 5 a month when I worked as a claims adjuster. When I quit that work 10 years ago the migraines ceased. Plus I have been on beta-blockers for 20 years. Just recently switched from Timolol to Propanonal which might be a problem. I am also on 40mg Lexapro. Stress makes me clench my jaw which aggravates everything. Been taking Klonopin PRN. So far all the Thyroid test have come back negative. But I don’t believe them. Thyroid disease and diabetes runs in the family. Was glad to read your article. I too have a recessed chin. Do you think a goiter could be related to the apnea and hiatal hernia.? I just want to understand what’s going on in my body. So many doctors don’t want us lay-people/patients to know.

  27. I found out I had a HH 20 years ago when I went to doctors with acid reflux. Never told the type or size. Changed diet, got off prevacid no more reflux. 15 years later after having attacks of chest, back, stomach pain, throwing up and chills. Shortness of breath, not sleeping for years. Thought may be ulcers,copd, and menopause. Finally after getting insurance, found a doctor, told about shortness of breath and other painful attacks. Had a sonogram for gallbladder( my suggesting), nothing showed up. After all well care check ups, doctor says see you next year. What about my shortness of breath? She says we can do an xray but don”t think we’ll find anything. Large HH found! I had forgotten I had one but didn’t know how bad it was. Had endoscope and pH impedance test done. Conclusion, not causes SOB. After overnight oximeter test put on oxygen at night. After 4 months waiting for pulmonary doctor, had all heart test check ups. After overnight sleep test told l may need to do another one because l didn’t have any problems in time as per insurances time limit? Really? So a few days ago went to urgent care who sent me to er for a pain in hip and lower abdomen. Still don’t know what the problem is.White blood count up and CT scan showed gallstones hiding behind a very large HH. ER doctor concerned about the size of hernia. But said he wasn’t an expert, should see specialist. Haha, What good that has been! Talked to the nurse, we talked about going with our gut and knowing our own bodies. Gave me names of good surgeons and a new doctor. I really wondered about the HH causing SOB and sleep apnea, has been on my mind but so call experts say NO. Gastro and heart docs made comments as it might be psychological. I eat healthy but about 25 lbs overweight. Hard to exercise with these issues. I am 59 yr female, have helped build 3 house, remodel 2. Do my own yard work with the exception of being limited this past year because of these health issues. I have a wonderful relationship with my Lord and content with my mental life. So this “New Year” it’s time to take charge until I find a doctor smart enough to think beyond the schools they went to too many years ago and listen to their patients….Merry Christmas, praying for a blessed New Year to all

  28. I am a retired RN and was diagnosed with obstructive sleep apnea in 2002. For several years, I did alright and slept so much better except waking to an air leak when I turned over.

    Not sure why I stopped, but when I restarted I had lots of coughing and tried a couple more times since. A chronic cough returned in the last few years and all my pulmonary tests were negative. Previous to that a large hiatal hernia was found on my spinal MRI ! My internist, finally in 2015, put 2 and 2 together that I was having silent reflux during the night!

    I am using a oral appliance for the past 3 years with wonderful results. Now that I am Medicare age, and need a new appliance, I have been examining my ancient medical reports to show evidence that I had sleep apnea, before there was a sleep study done. I do not want to go back on CPAP because it finally dawned on me yesterday, why I had had a strangulating coughing with CPAP. I googled CPAP & HH to see if there was any information regarding CPAP causing HH and your website popped up. Your hypothesis is right on regarding hypopneas causing hiatal hernias!!!! Prior to being tested, I had more than a couple decades of reporting I had so many awakenings, but not one doctor caught on until 2002.

    So my personal hypothesis is that after gaining lots of weight at age 40, that I was having obstructive sleep apnea with loud snoring. That may have caused the hiatal hernia. The hiatal hernia became larger and I began to have silent reflux. The proton inhibitor has taken care of waking up coughing. I am not willing to have the hiatal hernia repaired. The oral appliance keeps my lower jaw forward and I sleep like a baby.

    Thank you Dr. Park for your insight.

  29. I have a hiatal hernia, suffer from acid reflux, have a deviated septum and have sleep apnia. Your thoughts on hiatal hernia is a good one. My thought at least in my case is my hiatal hernia causes sleep apnia. When you relax when you sleep your stomach pushes your esophagus up and causes the obstruction which inhibits your breathing.

  30. Update: Had surgery on hiatal hernia and gallbladder in February. Almost all of my stomach was in my chest, pushing on my heart and lung (causing bottom of lung to collapse) No more shortness of breath. Feel great! Can still hear crackling in my breathing so checking with pulmonary doc to see if lung hasn’t fully inflated. Other than that feeling much better. Heart palpitations stopped, no back pain, even hot flashes (thought from menopause) gone. No more bloating or back pain. Glad I had the surgery and it wasn’t as bad as I read online from others who had the surgery. Happy!!!!

  31. I’d like to share one thing that I’ve discovered about my own sleep disorders from UARS, that I’ve never really read about anywhere.

    My breathing problems (via UARS) are transient. By that, I mean my breathing only becomes labored if I focus very hard on letting my throat become completely relaxed. It’s something that didn’t show up on any endoscopic exam until I convinced the ENT to let me lie down and do this relaxation. Bam, I’m a case study in the works.

    So, my problem arises exclusively during the onset of Slow Wave Sleep. It is only in this stage of sleep that my body is so relaxed that my throat muscles cause labored breathing. In all other lighter stages, my body is alert enough to involuntarily hold my throat muscles open, and I can plow past any hypopneas that do happen without being aroused out of those stages of sleep.

    My five sleep studies all showed almost zero Slow Wave Sleep, but it was always explained to me as being an artifact of sleeping in a foreign environment. I suggest that this may be a primary indicator that a person should be checked out for the same thing I have, especially if there is no other obvious cause of your UARS or sleep apnea. A partial epiglottectomy, via robot, helped a bit, but I do believe that I need to undergo hiatal hernia surgery before the swelling in my throat goes down and makes the aforementioned muscle relaxation unproblematic.

    It took years for me to come to this (what I think is probable) conclusion, but I believe this is how my hernia/UARS evolved into this issue:

    Intense weightlifting (including heavy bench presses right on top of my lower esophageal sphincter) led to a hiatal hernia, which in turn caused inflammation in my throat leading to constricted airways that become problematic only in SWS when they try to totally relax–thus resulting in UARS and awful fatigue. Essentially reverse of the theory, but as was said, it’s all interrelated.

    My goal in life is to eventually get up the nerve to do the hernia surgery (the type with the magnetic band, a.k.a., “Linx”), and have the mental energy to start a non-profit that helps doctors research how many diseases’ symptoms are, in fact, caused directly from hard-to-diagnose sleep disorders. I firmly believe that many disease do not cause sleep disorders and fatigue directly, but second hand through affecting subtle and hard-to-diagnose changes in airways.

    Now here is my theory: Fibromyalgia, Lewy Body Dimentia, Sanfillipo-related sleep disorders (via neck/throat abnormalities caused directly by the disease), and of course, Chronic Fatigue Syndrome.

    And, skirting landmines–autism. What if it’s a sleep disorder that causes it, with all or most of the other risk factor/potential causes actually being contributors to the sleep disorder, and only indirectly causing autism? I wouldn’t commit my life savings to the theory, but I base this on the fact that the lower airways are developing rapidly at exactly the age when almost all autism begins, almost all people with the disorder have horrible sleep problems, and (cringing because I know this anecdotal)–because CFS (partially hereditary) runs in my family and four of my nephews have autism. I know…I know…

    It took seven (yes, seven) sleep specialists, five ENTs, and a neurologist before the mechanism of my fatigue was likely identified. How many people suffering from CFS and these other conditions rule out sleep disorders as a cause after getting only one, or even two, tests that don’t clearly show one?

    Me: 31 y/o CFS/UARS/hiatal hernia sufferer since I was 18, with a degree in mechanical engineering and a Master’s in Mech & Aerospace engineering in the works.

  32. Just reread my post…meant to say that I thought that all of those conditions (CFS, FM, etc.) seem to me to be excellent candidates for having sleep disordered breathing as in intermediary cause of fatigue-related symptoms. I don’t propose that all of these conditions are caused directly by disordered breathing necessarily, but rather that many of them may cause abnormalities that, in turn, cause the fatigue portion of the diseases’ symptoms. I understand that doctors know the immediate cause of some of these diseases already (e.g., Sanfillipo).

  33. Makes sense to me because I am on a breathing machine and I’m having symptoms of hiatal hernia.

  34. I have gastroesophigal reglux disease, had a deviated septum, dislocated jaws, high blood pressure that elevates hogh but told its not any problem with my heart but I do have a stent in my circumflex of my heart, have the start of bsrristers but not cancer, get a pain in my abdomin just below the central left of my ribcsge.lots of indigestion thats worse if I hsve to lift heavyobjetd orbend. Could I maybe have a hiatal hernis. If so what should I do. Also I hsve sleep apnes and intersidial lung disease.

  35. Great way of presenting your viewpoints! I keep looking forward to the proven of the hypothesis about the correlation of sleep apnea and hiatal hernias, thanks.

  36. I have had extremely loud snoring for years, with borderline sleep apnea. I had surgery to repair a ventral hernia and large diastatis last week, and the snoring has all but disappeared. It was an unexpected but welcome change.

  37. Doctor – I have both a hiatal hernia and moderate OSA, does fixing the OSA help to fix thr hernia. I am looking into doing the new inspire implant based surgery, but Im wondering if the hernia is causing my sleep apnea.

  39. Hello Dr. Park,
    Yes I think your theory holds considerable validity from my point of view. Here is why I came to see you about a year ago. I was the long distance runner and very thin, we discussed facial and jaw structure as a possibility. I was using a CPAP like advised with very low apnea numbers. But I keep complaining to my Doctors including my pulmonalogist and cardiologist of this strange pressure in my chest when I lied down especially on my back. I insisted they go back and look at CAT scan they had done of my heart and low and behold they found a descent sized hiatal hernia that no one had told me about or scene or that I ever knew had. So if I look at the time frame of when that CAT scan with contrast was done….. that was when I first noticed I was suddenly waking up feeling like I wasn’t breathing, startled awake etc. that went on for months and months. Anyways I am really interested in this theory and as far timing for me an my sleep apnea symptoms they are either causative from the hiatal hernia or highly circumstantial that they appeared at the same time. I am really interested in hearing what you think about this as I am trying to figure out what to do next. I do know that I have a deviated septum also but I think the hiatal hernia was or is the bigger culprit. Thank you for your continued research and sharing of knowledge in this field. PS I am the one who lives in Hawaii who you recommend someone on Oahu.

  40. Hello I totally believe in your hypothisis. I have hypopnea as well as a Hiatal hernia and have been suffering for a few years.I have high blood pressure controlled through medication I wear a Cpap machine at night but still snore and wake up often without much rest. I practice yoga and do deep breathing exercises. ‘Breath of Fire’ is one breathing exercise
    Maybe you would have a suggestion for me?

  41. Hi I have mild sleep apnea and hiatus hernia, and when I try to sleep I get a vice like grip feeling right where the hernia is (just at top of stomach)followed by breath being held and eventually gasping for air an awaken this happens bout every half hour on bad nights tonite being one of them it’s 7;20 am and I have not slept.dont know how much more of it I can take?

  42. Hi Dr. Park:

    This is the exact situation I seem to be in. Will hernia repair work in such a case? or will it fail?

    What came first? the apnea or the hiatus? I have developed LPR and tinnitus. I also had a stroke just over 2 years ago. My CPAP does not work and seems to permit more refluxate to reach the aero-digestive component. Steroid aerosols also do the same. Help?

  43. Mr. Miller,

    A hernia repair may help with your reflux, but in the presence of untreated apneas, it’s more like to come back. I see this happening quite often. It sounds like you may need to consider other options besides CPAP. Good luck.
