About Weight Loss Surgery
Dieting and exercise are not effective and durable solutions for people who attempt to lose weight and keep it off. Weight loss surgery is a proven way to fight obesity. Bariatrics shifts the body’s set-point, also known as a metabolic thermostat, resulting in rapid and long-term weight loss.
Weight loss surgery can cure obesity and its related diseases, like hypertension, type 2 diabetes, and heart conditions. It also lowers the risk of virus exposure, such as COVID-19 Coronavirus.
Mechanism of Action
Weight loss surgeries, also known as “Gut Cut,” can be classified into three broad categories, depending on the way the operation achieves weight loss; restrictive, malabsorptive, and a combination of restrictive & malabsorptive.
Restrictive procedures ‘restrict’ the stomach’s capacity, thereby reducing caloric intake. The smaller stomach capacity will induce the feeling of fullness quicker than normal, prompting the patients to eat less. This method is seen in procedures such as adjustable gastric banding, vertical sleeve gastrectomy (gastric sleeve), and gastric balloon.
Malabsorptive procedures reroute, rearrange, or remove part of the digestive system to reduce the body’s absorption of calories from food. They produce more weight loss than restrictive but also come with higher rates of complications and side effects. There are no stand-alone malabsorptive procedures being performed today, as all malabsorptive procedures are combined with restriction.
Combination procedures use both techniques (restrictive and malabsorptive) to produce high amounts of excess weight loss. Common combination procedures include gastric bypass and duodenal switch.
All the bariatric surgery options are done laparoscopically (minimally invasive) unless there are issues, like scar tissue from previous operations, that calls for traditional open surgery.
