Sleeve Gastrectomy Surgery in MRC Nagar, Chennai

Overview of Sleeve Gastrectomy

Being overweight or obese can make an individual feel beleaguered. The feeling is worse when you see others shedding off that extra fat through exercise and diet while you are struggling. However, sometimes things can go beyond your control. At this point, doctors recommend bariatric procedures or obesity control procedures.

Among the different forms of Obesity or Bariatric Surgeries available today, Sleeve Gastrectomy is a safe and remarkably successful method to attain weight loss.

About Sleeve Gastrectomy

Also known as gastric sleeve or vertical sleeve gastrectomy, it is a significant procedure involving the removal of almost 80 percent of the stomach.

In the open or traditional approach, the surgeon makes a big incision in the abdominal region, staples the stomach vertically, and removes most of your stomach. Then with the help of sutures or staples, the surgeon closes the edges of the remaining portion of the stomach. It leaves a narrow tube-shaped part, which is called the sleeve.

With just a small pouch that you can call a stomach, you start feeling full early compared to earlier. Thus, it restricts your food intake. This way, sleeve gastrectomy boosts weight loss. Since one of the parts of the stomach that is removed is the part that produces ghrelin (a hormone that makes you feel hungry), you do not feel much hunger either.

Today, another approach widely popular is the laparoscopic approach. In this, surgeons make 5-6 tiny cuts and complete the surgery using specialized instruments.

Who Qualifies for Sleeve Gastrectomy?

Usually, regular exercise and following a fixed diet can help in weight loss. Yet, many people do not benefit from these.

Sleeve gastrectomy is an option when your attempts to lose weight through other measures have failed to yield results. The criterion for this procedure includes:

  • A body mass index (BMI) that is 40 or more than that. (BMI is the value that shows whether you have a healthy weight as per your height)
  • If you are suffering from an obesity-associated health condition.

Occasionally, there can be cases where the BMI does not match the criteria, but the patients need to lose weight due to a specific health problem. In such cases too, sleeve gastrectomy is recommended.

Sleeve gastrectomy ensures substantial weight loss, which can protect you from potential life-threatening obesity-related health issues, such as:

  • Cardiovascular diseases

  • Obstructive sleep apnea
  • Stroke
  • Cancer

  • Chew your food properly before swallowing.

  • Take vitamins and minerals supplements to prevent nutritional deficiency.
  • Drink liquids half an hour after finishing your meal.
