Snoring, obstructive sleep apnea syndrome, and pregnancy

Obstructive sleep apnea syndrome (OSAS) is estimated to affect 5% of the population, and snoring is a problem for 6.7% of women. The relationship between OSAS and hypertension is becoming more evident. One of the most serious complications in pregnancy is eclampsia, and women with this condition also present an exaggerated pressor response to nocturnal apnea [1]. Three cases are described illustrating these conditions.
