Snoring may also occur when you sleep on your stomach because snoring is mainly due to the vibrating sound caused by exhaling and inhaling gas vibrating the mucous membrane of the pharyngeal cavity during sleep. Someone may be able to reduce the snoring sound when sleeping on his or her stomach. If the pharyngeal cavity mucosa is thicker or the pharyngeal cavity is narrower, exhaling and inhaling gas while sleeping on your stomach will also vibrate the pharyngeal mucosa causing and snoring. If you want to solve snoring, it depends on what causes it. If it is due to hypertrophy of the soft palate mucosa, there may be some relief when sleeping on your stomach. If the tonsils are particularly enlarged, the jaw is narrower or the patient is obese, this change in position will not improve the snoring symptoms significantly. If you want to solve the snoring problem, you have to give the appropriate treatment according to different conditions.
