Obstructive Sleep Apnea. Obstructive sleep apnea (OSA) is a sleep-related breathing disorder that involves a decrease or complete halt in airflow despite an ongoing effort to breathe. It occurs when the muscles relax during sleep, causing soft tissue in the back of the throat to collapse and block the upper airway. Obstructive Sleep Apnea Syndrome (OSAS) is the most common form of sleep apnea, and is characterized by upper airway obstructions that occur repeatedly during sleep and cause breathing to stop (“apnea”), when the obstruction is complete, or to be shallower than normal (“hypopnea”), when the obstruction is partial.
Obstructive sleep apnea is a common sleep disorder and is estimated to have an incidence of 24% in men and 9% in women. However, many authors believe that up to 93% of women and 82% of men with moderate to severe OSA remain undiagnosed. There is a strong link between sleep disordered breathing and hypertension, believed to be due to sleep Cited by: Excess weight. Most but not all people with obstructive sleep apnea are overweight. Fat deposits around the upper airway may obstruct breathing. Medical conditions that are associated with obesity, such as hypothyroidism and polycystic ovary syndrome, also can cause obstructive sleep apnea.
