Sleeve Gastrectomy Surgery In India

Sleeve gastrectomy surgery, also known as gastric sleeve procedure is a weight-loss procedure that involves decreasing the stomach size surgically. During the procedure, about 80 to 90 percent of the stomach is removed permanently, leaving a tube-like portion of the stomach in place. This drastic decrease in stomach size means the person can intake only a limited quantity of food at a time, which in turn decreases the calories intake of the body, leading to weight loss.

In addition to lesser food intake,  the procedure prompts hormonal changes that assist with weight loss. The hormonal changes also help relieve conditions associated with obesity, such as high blood pressure, heart diseases etc.

Why is it done

Weight loss is the primary goal of sleeve gastrectomy surgery. However, it also reduces your risk of potentially life-threatening problems that are weight related such as:

  • Gastroesophageal reflux disease (GERD)
  • Asthma
  • Heart disease
  • Infertility
  • High blood pressure
  • Diabetes
  • High cholesterol levels
  • Sleep apnea

Sleeve gastrectomy is recommended only when diet control and other non-invasive weight loss methods have failed.

In general, your doctor will recommend sleeve gastrectomy as a solution for weight loss if :

  • You have a body mass index (BMI) of  40 or higher which is regarded as extreme obesity.
  • You have a BMI of 35 to 39.9 (obesity), and you have a serious weight-related health issue, such as type 2 diabetes, high blood pressure etc.
  • In rare cases, you may qualify for weight-loss surgery even if your BMI is 30 to 34 but you have serious weight-related disorders.

While deciding to undergo sleeve gastrectomy, you must also be willing to make permanent lifestyle changes to lead a healthier life. You will be required to adhere to long-term follow-up plans that include diet monitoring, lifestyle and behavioral changes.

The procedure

Sleeve gastrectomy is most commonly performed laparoscopically. This is a less invasive technique in which multiple small incisions are made in the body through which a tiny camera called laparoscope is inserted. The surgeon watches the surgery site on a screen and performs the operation with the help of specialized tools.

The surgeon proceeds to create a narrow sleeve by stapling the stomach vertically and  then removing the larger part of the stomach. The remaining stomach resembles a banana in shape and is much smaller than the original.


As with any major surgery, sleeve gastrectomy poses its own potential risks such as:

  • Excessive bleeding
  • Infection of the surgical wound
  • Blood clots
  • Leakage at the sutured edges of the stomach
  • Sleeve dilation
  • Stomach ulcers
  • Gastroesophageal reflux disease (GERD)
  • Low blood sugar
  • Malnutrition
  • Nausea and vomiting
  • Gallstones

After sleeve gastrectomy surgery, you will be asked to follow a specific diet with certain restrictions. Vitamin supplements and injections will be advised. Frequent medical checkups and laboratory tests are done to monitor your health post surgery.

You may experience certain changes in your body post surgery as your body reacts to the rapid weight loss in the first three to six months after sleeve gastrectomy. Body aches, headaches, feverishness, hair loss, mood swings, and cold sweats may be noticed.
