Sleep apnea is very common in women with Polycystic Ovary Syndrome (PCOS). This sleep disorder is likely also related to obesity, in addition to other important aspects such as apnea during pregnancy, which poses a risk for hypertension and gestational diabetes. Starting from perimenopause and late postmenopause, the frequency of sleep disorders increases, as well as the cardiovascular risk due to the decline in estrogen and progesterone concentration levels.
