Have you tried all the weight-loss plans and still didn’t achieve desired results? Are you tired of dieting and spending long hours for workouts?

Don’t worry, Bariatric Surgery can make you lose those extra pounds that made you obese. Bariatric surgery is the weight loss surgery which is an option for people who have a BMI over 35. It is a boon to obese people who cannot achieve significant weight loss through diet and exercise or suffer from serious health issues that result from obesity. Having a weight-loss surgery because of obesity is a major decision that could alter one’s life forever. It changes what and how much a person can eat.

Most of the bariatric surgeries are performed laparoscopically. And the most common bariatric surgeries gastric bypass, sleeve gastrectomy, adjustable gastric band and biliopancreatic diversion with duodenal switch. Today, let us know about one bariatric surgery which is most commonly performed known as “Sleeve gastrectomy”.

Patient Story

Mr. Aseel Abdullah Joan is a Yemen National suffering from overweight since a long time, Earlier, he was extremely depressed because of being overweight (150 kilos) and tried many things for weight loss. Finally, he consulted Dr Mahidhar Valeti, Consultant Bariatric Surgeon at MaxCure Hospitals and decided to opt for sleeve gastric bypass surgery. Within one and a half month, he has reduced to 130 kilos. 


Gastric Sleeve Surgery removes 70% of the stomach where the hunger is produced. This quickly and effectively reduces hunger and leads to excellent results in the super obese and other classes of obesity.

What is the difference between Open and Laparoscopic Surgery?

The open approach involves an eight – ten inch incision to open the abdomen and perform the weight-loss surgery in open view of the surgical team. The laparoscopic approach creates 5 or 6 small incisions (1/4 or 1/2 inch long) instead of the 1 larger incision. In the laparoscopic approach, a small fiber optic (the laparoscope) tube, connected to a video camera, is inserted through the small abdominal incisions.

This helps the surgeon to get a magnified view of the patient’s internal organs on a television screen placed next to the operating table. The entire bariatric operation is performed inside the abdomen, after the gas has been used to expand it, with the instruments inserted through the various small incisions.

Open surgery might be a better option in certain cases. Who are have a high level of obesity problem, have had stomach surgery before, or have other complex medical problems, you may need open surgery.

Sleeve Gastrectomy

The Laparoscopic Sleeve Gastrectomy is known as the sleeve. In this procedure, almost 80 percent of the stomach is removed and the remaining stomach seems to be a tubular pouch that appears similar to a banana.

The Procedure

In most of the cases, sleeve gastrectomy is done laparoscopically. The procedure involves making of five or six small incisions in the abdomen and an instrument called laparoscope is inserted through these incisions.

During a sleeve gastrectomy, the stomach is divided along its vertical length to create a long, slender pouch or sleeve. And the remaining part of the stomach about 80 percent is removed.

In sleeve gastrectomy, no intestines are removed or bypassed as done in gastric bypass. This procedure works by several mechanisms. The main mechanism is the new stomach pouch can hold only a smaller volume than the normal stomach which helps to significantly consume a less amount of food.

The surgery affects the gut hormones that influence a number of factors including hunger, satiety and blood sugar control. The sleeve gastrectomy is very effective in terms of weight loss and improving type-2 diabetes, independent of weight loss.


  1. Limits the amount of food the stomach can hold
  2. It takes only around two hours to complete the procedure and relatively short hospital stay of approximately two days.
  3. Results in rapid and reliable weight loss and maintenance of weight.
  4. Preserved stomach function as there is no change in nerves of the stomach and outlet valve.
  5. Reduced risk of developing vitamin and mineral deficiencies as the consumed food follows the normal digestive path.


  1. As there is no intestinal bypass in sleeve gastrectomy, there may be a possibility for inadequate weight loss or weight gain.
  2. Higher BMI patients will more likely need to have a second stage procedure which helps them to lose rest of the excess weight.
  3. Soft calories such as ice cream, milkshakes etc can be absorbed which may slow down the weight loss.
  4. It is an irreversible process.
