The estimated number of bariatric surgery procedures in the United States has steadily increased since 2011, with 196,000 procedures taking place in 2015, according to the American Society for Metabolic and Bariatric Surgery. As patients experience the massive benefits of significant, meaningful weight loss after bariatric surgery, these procedures have become increasingly popular for those aiming to lose weight.
Weight loss surgical procedures restrict the amount of food that the stomach of a patient can hold, which causes a quicker feeling of fullness. Some bariatric surgeries may also or alternatively interrupt the digestive process or impede absorption of nutrients. By altering the body in this way, obese patients who undergo this type of surgery restrict caloric intake and/or nutrient absorption and lose weight.
