Gastric Sleeve

Gastric sleeve surgery, medically known as sleeve gastrectomy, is a surgical weight-loss procedure in which a portion of the stomach is removed to create a smaller, tube-shaped stomach.

The procedure reduces stomach volume and lowers the production of ghrelin, a hormone associated with appetite. This helps patients feel full after smaller meals and supports long-term dietary control.

Gastric sleeve surgery does not involve intestinal bypass or implants. It is performed as a standalone procedure and is widely used in the management of obesity.

Gastric sleeve surgery is performed laparoscopically using small incisions and a camera-guided surgical system.

Procedure steps:

• Anesthesia: The procedure is performed under general anesthesia.

• Laparoscopic access: Small incisions are made in the abdomen to insert surgical instruments.

• Stomach reduction: Approximately 70–80% of the stomach is removed, leaving a narrow sleeve.

• Stapling and sealing: The remaining stomach is stapled and sealed to prevent leakage.

• Recovery: Patients are monitored and typically discharged within 1–2 days.

The reduced stomach size helps limit food intake and supports gradual, sustained weight loss.

Eligibility for gastric sleeve surgery is based on medical evaluation and clinical criteria. Candidates may include individuals who:

• Have a body mass index (BMI) of 35 or higher

• Have a BMI of 30–34.9 with obesity-related conditions such as diabetes, hypertension, or sleep apnea

• Have attempted supervised weight-loss programs without long-term success

• Are medically and psychologically prepared for lifestyle changes after surgery

Before surgery, patients undergo assessment with a bariatric surgeon, dietitian, and other specialists to ensure suitability and readiness for the procedure.

Gastric sleeve surgery may help patients achieve:

• Sustained reduction in excess body weight

• Improved management of obesity-related conditions such as diabetes, hypertension, and sleep apnea

• Reduced appetite due to hormonal changes

• Improved mobility and physical function

• No intestinal rerouting or malabsorption

• Faster recovery compared to some other bariatric procedures

Long-term results depend on adherence to dietary guidance, lifestyle modification, and follow-up care.

Recovery after gastric sleeve surgery varies by individual, but typically includes:

• Hospital stay: 1–2 days

• Diet progression: Liquid diet → pureed foods → soft foods → solid foods over several weeks

• Activity: Light activity within 7–10 days; gradual return to exercise after 4–6 weeks

• Follow-up: Regular medical and nutritional follow-ups to monitor progress

Patients receive long-term nutritional guidance and medical monitoring to support weight management and overall health.

Gastric sleeve surgery is considered safe when performed by qualified bariatric surgeons, but potential risks include:

• Bleeding or leakage along the staple line

• Infection or blood clots (rare)

• Temporary nausea or reflux

• Nutrient deficiencies (iron, vitamin B12, calcium)

• Gastroesophageal reflux disease (GERD)

All risks are discussed during consultation, and preventive measures are taken to minimize complications.

The cost of gastric sleeve surgery varies based on:

• Surgeon’s experience

• Hospital and facility standards

• Preoperative investigations

• Anesthesia and hospital stay

• Postoperative care and nutritional follow-up

A personalized cost estimate is provided during consultation following medical evaluation.
