Gastric sleeve surgery, or sleeve gastrectomy, is a popular weight loss procedure that reduces the size of the stomach, helping limit food intake. If you’re considering this surgery, understanding what happens before and after the procedure is crucial for a smooth and successful outcome.

Before Gastric Sleeve Surgery: Preparing for the Procedure
Preparation is key. Here’s what you can expect:
- Medical Evaluation: Your healthcare provider will conduct tests and review your medical history to ensure you’re a suitable candidate.
- Nutritional Counseling: A dietitian will guide you through a pre-surgery diet to shrink your liver, making surgery safer. You’ll need to follow a strict, low-calorie diet for one to two weeks before the procedure.
- Psychological Assessment: A psychologist may assess your readiness for the lifestyle changes required post-surgery, including long-term commitment to new habits.
- Quit Smoking and Alcohol: You’ll be asked to stop smoking and drinking alcohol weeks before surgery to reduce risks.
- Pre-Operative Instructions: Your surgeon will give instructions on fasting, medications to avoid, and what to do on surgery day.
The Surgery: What Happens During Gastric Sleeve Surgery
Gastric sleeve surgery is performed laparoscopically, using small incisions. A portion of the stomach is removed, creating a smaller, tube-like “sleeve.” The surgery usually takes one to two hours, and most patients stay in the hospital for one or two days afterward.
After Gastric Sleeve Surgery: Recovery and Adjustments
Post-surgery recovery is essential for long-term success:
- Immediate Recovery: You’ll be on a liquid diet for the first few days to help your stomach heal. Discomfort such as nausea or pain is common but manageable with medication.
- Diet Progression: Over several weeks, you’ll transition from liquids to pureed foods, then soft foods, and finally solid foods, following your healthcare team’s guidance.
- Weight Loss and Results: Most patients experience rapid weight loss in the first six months to a year. Long-term success depends on maintaining healthy eating habits and incorporating exercise.
- Lifestyle Changes: Gastric sleeve surgery requires significant changes in eating habits. Small portions and healthy food choices are key. Many find joining a support group helpful during their weight loss journey.
- Follow-Up Care: Regular appointments with your healthcare team will ensure you’re progressing well.
