Obstructive sleep apnea is a condition that affects millions of Americans. Signs and symptoms of sleep apnea Include daytime sleepiness, snoring, witnessed episodes of cessation of breathing while sleeping, frequent arousals at night, and waking up gasping at night. If left untreated it can have a significant effect on your quality of life by causing excessive daytime sleepiness, low energy, depression, and weight gain. Untreated sleep apnea also increases a patient’s risk of developing hypertension and diabetes, heart attacks·and strokes. The doctors at Southeast Michigan Ear, Nose, and Throat are able to perform sleep studies to diagnose sleep apnea.
