There’s been lots of studies in the past showing that obstructive sleep apnea during pregnancy can be potentially dangerous to the mother and baby’s health, but unfortunately, these finding haven’t made their way into being used in clinical practice. Here’s another study that supports the need to screen for OSA on a regular basis: Snoring before or during pregnancy was found to be associated with significantly higher rates of pre-term delivery and c-section rates. Women who snored were 2/3 more likely to have smaller babies and about 2 times more likely to undergo a c-section. Knowing that weight gain is a major risk factor for sleep apnea, it’s important to make sure you do or don’t have this condition if you’re pregnant. Lack of sleep and repeated oxygen deprivation is not very healthy for the mother or the baby.
