The purpose of weight loss surgery is to improve health, prevent the adverse effects of obesity on one’s health, and to therefore prolong ones life. On average, the following changes in several potentially life-threatening co-morbid conditions can be expected after weight loss surgery.

In addition to the above improvements in health, patients also often have an improved outlook and better self image, which sometimes helps them to come off of antidepressant medications if they are on them. There are also improvements in risks for cardiovascular disease, certain cancers as well as improvements in life-limiting health conditions which have been mentioned earlier.
