Patients who undergo weight loss surgery consume less food and absorb fewer calories. For adults who qualify, a combination of surgery, behavior modification and support may offer the first and only hope of a successful weight loss.
Research shows that weight loss surgery patients typically lose one-third of their initial weight within 18 months. In the first two years after surgery, patients typically lose from two-thirds to three-fourths of their excess body weight.
According to the
American Society for Metabolic and Bariatric Surgery and a study published in the Journal of the American Medical Association, weight loss surgery is among the most effective treatments for
metabolic diseases and other serious medical conditions. The
study showed that surgery patients lost between 62 percent and 75 percent of excess weight.
Surgery has been shown to resolve these issues at the following rates:
Type 2 diabetes: Remission in 76.8 percent and significantly improved in 86 percent of patients
Hypertension: Eliminated in 61.7 percent and significantly improved in 78.5 percent of patients
High cholesterol: Reduced in more than 70 percent of patients
Sleep apnea: Eliminated in 85.7 percent of patients
Also improved:
GERD
Incontinence

Joint disease, asthma and infertility
