Sleep Apnea and gastric bypass
There are several different reasons for sleep apnea including both central and obstructive. While sleep apnea is associated with morbid obesity and gastric bypass may produce an improvement, this is not always the case. It is very complex and you should undergo evaluation by a specialist.
Gastric Bypass Cures Sleep Apnea
The reason that morbidly obese patients develop sleep apnea is usually because of obstruction of the airway. As patients lose weight the obstruction decreases. When patients have lost a significant amount of weight sleep apnea goes away as well. There was a study done in 2007 which showed that gastric bypass cured or significantly improved sleep apnea in 86% of patients.
Bariatric surgery for sleep apnea
Most people with sleep apnea have excess neck adipose tissue which collapses as they sleep, causing obstruction and impaired air flow. The weight loss associated with gastric bypass reduces the amount of tissue, and as a result reduces the amount of obstruction and apnea. A 2013 study in the journal Obesity Surgery found that 75% of people undergoing bariatric surgery had improvement in sleep apnea. In addition, bariatric surgery has been shown to improve high blood pressure, diabetes, and high cholesterol - all known risk factors for developing cardiovascular disease.
