Additionally, we'll address frequently asked questions to help you make an informed decision about this life-changing procedure.

What is Sleeve Gastrectomy?

Sleeve gastrectomy, also known as the gastric sleeve surgery, is a surgical procedure designed to help individuals achieve significant weight loss and improve their overall health. This minimally invasive surgery involves the removal of a portion of the stomach to reduce its size and capacity. The resulting smaller stomach resembles a sleeve or tube, hence the name.

Here's how it works:

1.Stomach Reduction: During sleeve gastrectomy, approximately 80% of the stomach is surgically removed, leaving behind a much smaller, banana-shaped stomach pouch.

2.Reduced Appetite: With the smaller stomach size, patients feel full after consuming smaller portions of food, which leads to a decrease in overall calorie intake.

3.Hormonal Changes: The surgery also influences hormones responsible for appetite regulation, helping patients feel less hungry and more satisfied with smaller meals.

Who Needs Sleeve Gastrectomy?

Sleeve gastrectomy is recommended for individuals who meet specific criteria, including:

1.Severe Obesity: Patients with a body mass index (BMI) of 40 or higher are often considered eligible for sleeve gastrectomy. It may also be considered for those with a BMI of 35 or higher who have obesity-related health issues.

2.Failed Weight Loss Attempts: Individuals who have tried and failed to achieve significant weight loss through diet and exercise.

3.Health Risks: Those facing health risks due to obesity, such as diabetes, hypertension, sleep apnea, or heart disease.

How is Sleeve Gastrectomy Performed?

Sleeve gastrectomy is performed through laparoscopic (minimally invasive) surgery, which involves small incisions and the use of a camera and specialized instruments. Here's a step-by-step overview:

1.Anesthesia: The patient is placed under general anesthesia to ensure they are comfortable and unaware during the surgery.

2.Incisions: Typically, 4-5 small incisions are made in the abdomen.

3.Stomach Division: The surgeon carefully removes approximately 80% of the stomach, leaving behind a narrow tube or sleeve.

4.Stapling: The remaining portion of the stomach is sealed using surgical staples.

5.Surgical Closure: The incisions are closed with stitches or surgical staples.

The entire procedure usually takes about 1-2 hours. Most patients can expect to stay in the hospital for 1-2 days for recovery.

What to Expect From Sleeve Gastrectomy?

Short-term Effects:

- Rapid Weight Loss: Patients often experience significant weight loss within the first few months following surgery.

- Improved Health: Obesity-related health issues like diabetes and sleep apnea may show immediate improvement.

- Short Hospital Stay: Most patients are discharged within a day or two after the surgery.

Long-term Effects:

- Steady Weight Loss: Over time, patients can achieve and maintain a healthy weight.

- Dietary Changes: Patients need to adapt to a modified diet, focusing on protein-rich, nutrient-dense foods and smaller portions.

- Lifestyle Changes: Regular exercise and behavior modification are key to long-term success.

Cost of Sleeve Gastrectomy in Top Indian Hospitals

The cost of sleeve gastrectomy can vary widely depending on factors such as the hospital's location, the surgeon's experience, and the patient's specific needs. On average, in top Indian hospitals, the cost of sleeve gastrectomy can range from INR 3,00,000 to INR 5,00,000. It's important to consult with hospitals and healthcare providers to get an accurate estimate based on your individual case.

Risks of Not Getting Sleeve Gastrectomy

Choosing not to undergo sleeve gastrectomy when medically indicated can have significant consequences, including:

1.Continued Health Issues: Obesity-related health problems like diabetes, high blood pressure, and heart disease may worsen.

2.Reduced Quality of Life: Limited mobility, joint pain, and decreased life expectancy are common outcomes.

3.Emotional Impact: Ongoing struggles with obesity can lead to depression and anxiety.

Benefits of Sleeve Gastrectomy

Sleeve gastrectomy offers a range of benefits, including:

1.Substantial Weight Loss: Patients typically lose a significant amount of excess weight, leading to improved overall health.

2.Resolution of Health Issues: Many obesity-related conditions improve or resolve completely.

3.Enhanced Quality of Life: Patients often report increased energy, better mobility, and improved self-esteem.

4.Long-term Success: When combined with proper diet and exercise, sleeve gastrectomy can provide lasting weight loss results.


In conclusion, sleeve gastrectomy is a powerful tool for individuals struggling with obesity. It offers substantial weight loss, improved health, and an enhanced quality of life. However, it is essential to consult with healthcare professionals to determine if this procedure is right for you. Always make an informed decision and consider the potential risks and benefits before undergoing sleeve gastrectomy.
