Gastric Sleeve Surgery
Gastric sleeve surgery is also referred to as a vertical sleeve gastrectomy (VGS or the “sleeve”). During surgery, 75% to 80% of the stomach is removed laparoscopically. The "new" stomach can hold between 3 to 5 ounces. The reduction in stomach size during the gastric sleeve operation reduces food intake but does not lead to decrease absorption of food.
This bariatric surgery procedure removes the portion of the stomach which produces a hormone that stimulates hunger (ghrelin). The gastric sleeve is not reversible but can be converted to a Roux-N-Y-gastric bypass at a later time if needed. The Surgical Weight Loss Institute performs the sleeve gastrectomy with standard laparoscopy or Robotic assisted Laparoscopy.
Results: you can expect to lose 50-60% of excess body weight within three years.
Frequently Asked Questions About Gastric Sleeve Surgery
What are some of the gastric sleeve surgery results?
- Restricts Eating: During laparoscopic gastric sleeve surgery, a portion of the stomach is removed which produces a hormone that stimulates hunger (ghrelin). This reduces food intake but does not slow the absorption of food.
- Decreases Calorie Intake: As long as you eat regular high quality food, this system will decrease the calories eaten at a meal. If you drink high caloric beverages like milkshakes or regular soda then you can eat enough calories to prevent weight loss. If you eat calorie dense food like chips and candy then you will prevent weight loss and can even continue to gain weight.
How much weight will I lose after gastric sleeve surgery?
- With good follow-up, patients can expect to lose 50-60% of their excess body weight within three years with an average weekly weight loss of 1-2 pounds.
- For example, if you weighed 210 pounds above your ideal body weight, you could lose 105 pounds.
What are the health benefits of gastric sleeve surgery?
- Most individuals experience additional health benefits from gastric sleeve surgery.
- In 95% of patients the quality of life improved and obesity-related health conditions (called "comorbidities") were resolved or improved. In addition mobility and energy are usually greatly improved.
How long is the hospital stay for gastric sleeve surgery?
- After gastric sleeve surgery, you can expect to stay at the hospital for a minimum of one day.
What are the advantages of gastric sleeve surgery?
- The stomach and intestines remains intact
- Early return to work without weight lift restrictions
- Decreased risk of malabsorption of vitamins and minerals
