Sleeve Gastrectomy Surgery for Weight Loss: Procedure, Cost, Recovery, Benefits & Success Rate

Sleeve gastrectomy surgery, also known as gastric sleeve surgery, is one of the most effective bariatric surgery procedures for long-term weight loss in people struggling with obesity. During the procedure, approximately 75-80% of the stomach is removed, creating a smaller sleeve-shaped stomach that limits food intake and reduces hunger hormones. This helps patients achieve significant and sustainable weight loss while improving obesity-related conditions such as type 2 diabetes, hypertension, sleep apnea, and joint pain. If diet, exercise, and medications have not provided lasting results, sleeve gastrectomy may be a safe and effective treatment option for achieving healthier weight management and improving overall quality of life.

What is Sleeve Gastrectomy Surgery?

Sleeve gastrectomy, commonly referred to as gastric sleeve surgery, is a minimally invasive bariatric surgery performed to help individuals with obesity lose weight.

The procedure involves permanently removing a large portion of the stomach, leaving behind a narrow tube like stomach or “sleeve.” The smaller stomach reduces food capacity and lowers the production of ghrelin, the hormone responsible for stimulating hunger.

As a result, patients feel full sooner, consume fewer calories, and experience reduced appetite, leading to significant weight loss over time.

Why is Sleeve Gastrectomy Performed?

Sleeve gastrectomy is recommended for individuals who are unable to achieve healthy weight loss through lifestyle modifications alone.

Conditions Improved by Sleeve Gastrectomy

  • Obesity and morbid obesity
  • Type 2 diabetes
  • High blood pressure
  • Obstructive sleep apnea
  • High cholesterol levels
  • Fatty liver disease
  • Polycystic Ovary Syndrome (PCOS)
  • Gastroesophageal reflux disease (GERD) in selected cases
  • Osteoarthritis and joint pain
  • Cardiovascular disease risk

Are you going through any of these symptoms?

Who is Eligible for Bariatric Surgery?

A bariatric surgeon evaluates several factors before recommending sleeve gastrectomy surgery.

BMI Criteria for Sleeve Gastrectomy

You may be eligible if:

  • BMI of 40 kg/m² or higher
  • BMI of 35 kg/m² or higher with obesity-related health conditions
  • BMI between 30-34.9 kg/m² in selected patients with uncontrolled metabolic disease
  • Previous unsuccessful attempts at weight loss through non-surgical methods

Additional Eligibility Requirements

  • Age typically between 18 and 65 years
  • Commitment to long-term dietary and lifestyle changes
  • No uncontrolled psychiatric illness
  • Ability to attend regular follow-up appointments

Types of Sleeve Gastrectomy Surgery

Laparoscopic Sleeve Gastrectomy

Laparoscopic sleeve gastrectomy is the most commonly performed weight loss surgery. It uses small incisions, a camera, and specialized instruments to remove a large portion of the stomach.

Benefits include:

  • Smaller scars
  • Less pain
  • Shorter hospital stay
  • Faster recovery
  • Reduced risk of complications

Robotic Sleeve Gastrectomy

Robotic sleeve gastrectomy uses robotic-assisted technology controlled by an experienced bariatric surgeon.

Advantages include:

  • Enhanced surgical precision
  • Better visualization
  • Improved dexterity
  • Reduced blood loss
  • Potentially quicker recovery

  • Blood tests
  • ECG
  • Chest X-ray
  • Nutritional assessment
  • Psychological evaluation

The procedure is performed under general anesthesia.

3. Creation of Gastric Sleeve

The surgeon:

  • Makes small abdominal incisions
  • Inserts a laparoscope or robotic instruments
  • Removes approximately 75-80% of the stomach
  • Creates a narrow gastric sleeve
  • Uses surgical staplers to seal the remaining stomach

4. Leak Testing

The newly formed stomach is checked for leaks before completing the procedure.

5. Recovery Room Observation

Patients are monitored closely before being shifted to their hospital room.

The surgery typically takes 60-120 minutes.

Surgery

Although sleeve gastrectomy is generally safe, every surgical procedure carries some risks.
