Bariatric surgery


, also known as weight loss surgery, is a surgical procedure performed on individuals with severe obesity to assist in weight loss. It involves modifying the digestive system to restrict food intake and/or alter the absorption of nutrients. Bariatric surgery is typically considered for individuals who have not been successful in achieving significant weight loss through other methods such as diet and exercise.

There are several types of bariatric surgeries, including:

  1. Gastric Sleeve Surgery (Sleeve Gastrectomy):

    • In this procedure, a large portion of the stomach is removed, leaving behind a smaller, banana-shaped sleeve. The reduced stomach size restricts the amount of food that can be consumed, leading to reduced calorie intake and weight loss.

    • The procedure also impacts the production of certain gut hormones that regulate hunger and satiety.


  1. Gastric Bypass Surgery:

    • Gastric bypass surgery involves creating a small stomach pouch by dividing the stomach and then connecting it to the small intestine, bypassing a portion of the digestive tract.

    • This procedure restricts the amount of food that can be consumed and alters the digestion process, reducing calorie absorption and promoting weight loss.

    • Gastric bypass surgery also affects the production of gut hormones, which can help control appetite and improve metabolism.


  1. Adjustable Gastric Band:

    • This procedure involves placing an adjustable silicone band around the upper part of the stomach, creating a small stomach pouch. The band is connected to an access port under the skin, allowing for adjustments to control the level of restriction.

    • The band limits the amount of food that can be consumed at one time and promotes a feeling of fullness.


  1. Biliopancreatic Diversion with Duodenal Switch:

    • This surgery is a more complex procedure that involves removing a portion of the stomach and rerouting the small intestine to reduce the amount of calories and nutrients absorbed.

    • It combines a sleeve gastrectomy with a bypass of a significant portion of the small intestine.


Bariatric surgery is not a quick fix for weight loss but rather a tool to assist individuals in achieving long-term weight loss and improved health outcomes. It requires careful evaluation, pre-operative preparation, and ongoing post-operative care, including dietary and lifestyle changes, regular follow-ups, and support from healthcare professionals.

It's important to note that bariatric surgery is a major procedure and carries potential risks and complications. Therefore, it should be considered only after a thorough evaluation by a specialized healthcare team and after other weight loss methods have been explored and found ineffective. The decision to undergo bariatric surgery should be made in consultation with healthcare professionals who can assess an individual's specific circumstances and provide appropriate guidance.
