Gastric Sleeve Surgery: Comprehensive Overview

Gastric sleeve surgery (sleeve gastrectomy) is a weight-loss procedure that removes approximately 80% of the stomach, leaving a narrow banana-shaped sleeve. This restricts food intake and promotes weight loss.

Procedure

• Typically performed laparoscopically through small abdominal incisions.
• Surgeon removes ~80% of stomach; remaining sleeve is stapled/sutured closed.
• Surgery duration: 1–2 hours.

Benefits

• Average weight loss: 60–70% of excess body weight.
• Improvement/resolution of obesity-related conditions: sleep apnea, type 2 diabetes, hypertension, heart disease.
• Improved satiety and reduced hunger.
• Less invasive than gastric bypass with lower complication risk.

Risks and Complications

• Bleeding, infection, blood clots
• Nausea, vomiting, diarrhea
• Staple line leakage
• Hernias
• Nutritional deficiencies (iron, vitamin B12)
• Possible revision surgery for insufficient weight loss

Recovery

• Hospital stay: 1–2 days.
• Strict diet progression: liquids → solid foods.
• Regular follow-up appointments for monitoring.

Gastric sleeve is a major surgical decision requiring lifelong commitment to healthy diet and lifestyle changes for long-term success. Discuss benefits and risks thoroughly with a healthcare professional.
