By UTMB’s Dr. Victor Sierpina: Do you snore or know somebody who does? Snoring is usually a benign process caused by vibration of tissue in the back of the throat. While it can be associated with serious problems like obstructive sleep apnea that require medical or surgical intervention, most of the time the causes are more straightforward. If you have a lot of daytime drowsiness and don’t seem to get restful sleep, it might be worth checking out.
