Women with OSA appear to be heavier than their male counterparts. However, in a large community-based study, weight loss was found to be a more effective treatment strategy in men compared to women (96). Perhaps this difference may be explained by gender differences in the distribution of body fat. Men are more likely to gain and lose weight in their upper body, which appears more directly related to upper airway resistance loading.
Bariatric surgery, including gastric bypass, jejunoileal bypass, and gastro-plasty, is often recommended for treatment of morbid obesity, particularly when associated with other medical complications. It has been shown to effectively decrease AHI and treat OSA (97). Nearly 80% of patients who undergo bariatric surgery are female. Men are reported to have a higher risk of postoperative mortality (98), and therefore may not be good candidates for this method of weight loss.
