Qualifications for Bariatric Surgery

Bariatric surgery, or weight-loss surgery, provides a long-lasting weight-loss solution for obese patients. The surgery, whether it would be a gastric bypass or gastric sleeve, makes changes to the stomach and digestive system that limits the amount of food that can be eaten and how many nutrients can be absorbed.

Despite being a recommended surgery for obese patients, many criteria must be met in order to become a candidate. Generally, most patients will qualify for bariatric surgery if they’re at least 100 pounds over their ideal body weight or if their BMI is 35 or 35 to 39.9, with two or more comorbidities.
