Is snoring related to obesity?

Yes but...: Not all snoring is caused by obesity and not all obese patients snore. If your or someone you know snores and is obese, often he/she can have obstructive sleep apnea (osa). These folks don't sleep well because their breathing is interrupted. Then, they fall asleep during the day. A sleep study is indicated, because a breathing machine at night can help lots. The pmd can write prescr for study.

Yes: Normal weight people can snore too but obesity can definitely increase risk of snoring. The extra fat in the upper throat, along with fatter, bigger structures in the upper throat (uvula, tonsils) will sag and become more "floppy" when you sleep, closing on the trachea causing you to snore. The outside of your neck also drag down on your throat, again decreasing the breathing tube, increase snore.

Yes and no: Obesity is a major contributor of an obstructed airway during sleep, but there are plenty of non obese people who snore. There are many causative factors with snoring and you should see a doctor about addressing as many of these factors as possible, not just obesity.
