Carrying extra weight may be a key contributor to your OSA.
Excess weight is considered the major contributing factor to the development of OSA.
Being overweight is not the only contributing factor to OSA. Weight loss may improve the severity of obstructive sleep apnea. In some cases weight loss may eliminate OSA. Only your sleep physician can advise you on whether weight loss may eliminate the need for medical treatment such as CPAP.
Weight loss in addition to CPAP therapy will further enhance the treatment of many of the health effects associated with previously untreated OSA. Examples include an improvement in Type II diabetes and high blood pressure.
