People who have this condition often snore loudly or stop breathing for a few seconds or more during sleep. People with apnea often don't know they have it because they never remember waking up. But apnea can lead to other health problems, including heart disease, high blood pressure, type 2 diabetes, or sudden death from lack of oxygen.
Many research studies have shown that sleep-disordered breathing, such as sleep apnea, can be ameliorated with a custom-made dental appliance.
Symptoms of obstructive sleep apnea include loud snoring and arousals from sleep which lead to poor quality of life and serious medical problems, but many patients are unaware they have the disease because they often do not remember these arousals.
