Snoring is quite common, and most people think of it as nothing more than an annoying fact of life. The reality is that snoring can be a sign of more serious health issues, including sleep apnea. Sleep apnea is a condition that can contribute to high blood pressure, hypertension, and COPD. It usually results in fatigue, mental fuzziness and low energy. Sleep apnea occurs at night and can be diagnosed without blood tests in most cases. One of the most successful treatments for this condition is done by dentists with the fabrication of an oral device that is worn at night.
