If you snore, you should first see your doctor to determine if you do have sleep apnea. In a recent study at Stanford University, one out of every three heavy snorers was found to have severe sleep apnea. The doctor may schedule you for a sleep stoudy. For this study, you will need to spend the night in a sleep laboratory where your breathing and snoring will be monitored to determine the severity of your snoring and sleep apnea. If you do suffer from severe sleep apnea, you may need to be fitted for a CPAP machine.
Surgery is also a possibility.
However, if the sleep study rules out obstructive sleep apnea, or if the apnea is still very mild, then you might consider a visit to your dentist. A dentist can supply you with a dental appliance that can help you control your snoring. A dental appliance is a small plastic device that fits in the mouth. You wear it at night and it prevents the collapse of throat tissues that cause the snoring. These devices are easy to use and inexpensive.
