Sleep Apnea Treatments
Learn about the various treatment options for sleep apnea.
Sleep Apnea: Less Common Surgeries - Topic Overview
The first treatment options for obstructive sleep apnea (OSA) are lifestyle changes,such as losing weight or not drinking alcohol before bed,and continuous positive airway pressure (CPAP). If these do not work,or if an obvious tissue or bone problem is causing your sleep apnea,surgery is an option. Common surgeries for sleep apnea include uvulopalatopharyngoplasty (UPPP),which is removal ...
Sleep Apnea Complications - Topic Overview
Sleep apnea can cause you to stop breathing during sleep. When you stop breathing, the oxygen levels in your blood go down and carbon dioxide levels go up. This makes your heart and blood vessels work harder and can affect your heart rate and nervous system. This can lead to complications over time, such as:Low blood oxygen levels during sleep. These low levels as well as other factors such as fragmented sleep may lead to high blood pressure in the lungs (pulmonary hypertension) and in the rest of the body (hypertension).1 Nearly 50% of people who have sleep apnea have high blood pressure.2Heart failure. Changes in the body caused by sleep apnea increase the risk of heart failure.3Irregular heart rhythms, such as atrial fibrillation.4Coronary artery disease (CAD).A greater-than-normal number of red blood cells, which may cause the blood to thicken.Death caused by blood vessel disease that affects the brain or heart (stroke or heart attack).4Failure to resume breathing (respiratory
Stages of Sleep Apnea - Topic Overview
Sleep apnea occurs when you regularly stop breathing for 10 seconds or longer during sleep. It can be mild,moderate,or severe,based on the number of times an hour that you stop breathing (apnea) or that airflow to your lungs is reduced (hypopnea). This is called the apnea-hypopnea index (AHI). Mild apnea. Mild apnea is defined as 5 to 14 episodes of apnea or reduced airflow to the lungs ...
Causes of Snoring and Sleep Apnea - Topic Overview
Enlarged tissues in the nose,mouth,or throat can block the airway,causing snoring or obstructive sleep apnea (OSA). The airway can be blocked by: Enlarged tonsils and adenoids (the most common cause of sleep apnea in children). A larger-than-normal uvula (the small,finger-shaped piece of tissue that hangs down from the roof of the mouth into the throat). See a picture of the tonsils,...
Sleep Apnea: Fiber-Optic Pharyngoscopy - Topic Overview
Fiber-optic pharyngoscopy is a procedure that allows your doctor to look into the upper part of your respiratory system. He or she may use it to help decide how to treat your obstructive sleep apnea (OSA). You remain awake during the procedure. Your doctor gives you medicine ( anesthesia ) to numb your throat and then places a thin,flexible tube (endoscope) inside your nostril and gently ...
Snoring and Obstructive Sleep Apnea - Topic Overview
Snoring is a major symptom of obstructive sleep apnea (OSA). But even though most people who have sleep apnea snore,not all people who snore have sleep apnea. Snoring occurs when the flow of air from the mouth or nose to the lungs is disturbed during sleep,usually by a blockage or narrowing in the nose,mouth,or throat (airway). If you snore and do not have sleep apnea,your snoring is ...
