Bariatric surgery results in substantial and sustained weight loss. This weight loss leads to resolution or improvement of many of the medical conditions that were caused by the obesity.
Patients routinely experience resolution of diabetes, breathing problems such as sleep apnea and asthma, high blood pressure, and reflux disease. Patients often have much less body pain and substantially greater energy. Patients can usually eliminate 2/3 or more of their prescription medications. Patients have a lower risk of cancer after weight loss, and their life expectancy (chance of living to "average" old age) improves to near normal.

Excess weight puts intolerable strain on nearly every organ system of the body, and this strain results in major medical problems that go on to shorten life and reduce health. The good news is that many of the weight related medical problems will improve or resolve completely if a person is able to lose weight and keep it off.
