What is weight loss surgery?

Weight loss surgery, also known as bariatric surgery, is a medical procedure performed to help individuals lose weight by altering the digestive system. These surgeries are typically considered for people with severe obesity who have not been successful in losing weight through diet, medication and exercise alone. The primary goal of weight loss surgery is to reduce the size of the stomach or restrict the amount of food the stomach can hold, leading to reduced food intake and, consequently, weight loss.

Types of weight loss surgeries

Gastric Bypass: This procedure involves creating a small pouch at the top of the stomach and connecting it directly to the small intestine. This bypasses a portion of the stomach and small intestine, limiting the amount of food absorbed and reducing calorie intake. It also gives rise to profound hormonal changes that are responsible for sustained weight loss results after this procedure.

Mini Gastric Bypass: This procedure involves creating a large pouch of the stomach and connecting it directly to the small intestine. This bypasses a portion of the stomach and small intestine, limiting the amount of food absorbed and reducing calorie intake. It also gives rise to hormonal changes that can cure diabetes permanently in a majority of cases.

Sleeve Gastrectomy: In this surgery, a large part of the stomach is removed, leaving a banana-shaped or sleeve-like structure. The reduced stomach size limits the amount of food that can be consumed, leading to weight loss.

Gastric Banding: This involves placing an inflatable band around the upper part of the stomach, creating a smaller pouch. The band can be adjusted to control the size of the opening between the two parts of the stomach, regulating the amount of food that can enter.

FAQs

The pain after a routine bariatric surgery is very bearable, such that most patients are able to get up from bed and walk on the evening of surgery day. The level of pain experienced after bariatric surgery can vary from person to person, and it depends on factors such as the type of surgery performed, individual pain tolerance, and overall health. However, it’s common for patients to experience some discomfort and pain in the initial days.

Weight re-gain after bariatric surgery can occur if lifestyle changes, such as diet and exercise, are not maintained. Following postoperative guidelines and adopting a healthy lifestyle is crucial for long-term success in weight management.

Bariatric surgery in the elderly is generally considered on a case-to-case basis, taking into account overall health and potential risks. Age alone is not a strict contraindication, but individual health factors play a significant role in determining suitability.

The timeline for returning to normal activities after bariatric surgery varies, but most individuals can resume normal life gradually within a few weeks to a couple of months, following their healthcare team’s guidance.

After bariatric surgery, the initial diet typically involves liquids and gradually progresses to pureed and soft foods. Eventually, patients can introduce solid foods in smaller, nutrient-dependent portions, focusing on lean proteins, vegetables, and whole grains while avoiding high-calorie and sugary foods. The patients are provided with a diet chart which extensively details regarding the diet for the first six months after surgery and also suggests which foods need to be avoided mostly.

Coverage for bariatric surgery varies by insurance plan. Some insurance providers do cover it if specific criteria are met, such as a certain body mass index (BMI) and documented attempts at weight loss. Individuals should check with their insurance provider to determine coverage eligibility.
