What Is Gastric Sleeve Surgery?
Gastric Sleeve Surgery, also known as Sleeve Gastrectomy, is a type of bariatric (weight loss) surgery that involves removing a large portion of the stomach. The remaining part of the stomach is reshaped into a tube or sleeve, which significantly reduces the amount of food you can eat and helps in long-term weight loss.
This procedure is irreversible and is one of the most popular surgical weight loss options worldwide.
How Does Gastric Sleeve Work?
During the surgery:
1. About 75-80% of the stomach is removed, leaving a banana-shaped pouch.
2. The smaller stomach limits the amount of food you can eat.
3. The surgery also affects hormones related to hunger, such as ghrelin, reducing appetite.
The procedure usually takes about 60–90 minutes and is performed laparoscopically (minimally invasive).
Who Is a Candidate for Gastric Sleeve?
This surgery may be recommended for people who:
- Have a BMI of 40 or higher
- Have a BMI of 35 or higher with obesity-related health conditions
- Have tried but failed to lose weight with diet, exercise, or medications
- Are committed to making long-term lifestyle changes
Benefits of Gastric Sleeve
• Significant weight loss (50-70% of excess weight within 12-18 months)
• Reduction in hunger due to decreased ghrelin levels
• Improvement or resolution of obesity-related conditions (e.g., type 2 diabetes, high blood pressure, sleep apnea)
• Shorter hospital stay and faster recovery compared to other bariatric procedures
Potential Risks and Side Effects
While gastric sleeve is generally safe, potential risks include:
• Bleeding or infection
• Leakage from the staple line
• Nutritional deficiencies (iron, vitamin B12, calcium)
• Acid reflux or heartburn
• Temporary hair loss or fatigue in the first few months
Recovery Timeline After Gastric Sleeve
• Hospital stay: 1–3 days
• Return to work: Usually within 1–2 weeks
• Liquid diet: First 1–2 weeks
• Soft foods: Weeks 3–4
• Transition to solid foods: After 4–6 weeks
Post-Surgery Lifestyle Changes
For long-term success, patients must:
• Follow a healthy, portion-controlled diet
• Take vitamin and mineral supplements daily
• Engage in regular physical activity
• Attend follow-up appointments and support groups
