If you suffer from sleep apnea in Sunnyvale, contact Tooth Spa today. Sleep apnea can be a serious condition if left untreated. Most sleep apnea is caused by an obstruction in the throat which hinders the flow of incoming air. Snoring is present in most but not all cases. Some symptoms include daytime sleepiness, slowness in thought processing, obesity, gastric reflux, memory loss, and headaches. Snoring, which has always been considered to be just a nuisance, is very prevalent in people with this condition. Loud snoring, followed by a period of silence when breathing stops or slows, is a good indicator of sleep apnea.
