Individuals who are considering bariatric surgery for weight loss have multiple options. From traditional gastric bypass surgery to laparoscopic band surgery to gastric sleeve, each type of surgery has its own benefits and risks.
At UPMC Bariatric Services, our team of board certified surgeons will explain the pros and cons of gastric sleeve vs gastric bypass surgeries.
They’ll help you to make the right decision when considering bariatric surgery.
When deciding which surgery is right for you, it is essential to compare your options. You should understand the similarities and differences between the two types of bariatric procedures. When reviewing gastric bypass vs sleeve, there are a number of factors to consider:
Gastric Bypass Procedure vs. Gastric Sleeve Procedure: The Similarities
Gastric bypass and
gastric sleeve are very similar procedures. In both cases, the expected hospital stay ranges from 2-3 days and the procedures are not reversible. Although the methods differ, both operations reduce the amount of food you can eat before feeling full.
Gastric Bypass Procedure vs. Gastric Sleeve Procedure: The Differences
Gastric Bypass
- Procedure: A doctor attaches a small pouch to the intestine in order to bypass the stomach.
- Recovery Time: 2 to 4 weeks
- Risks and Complications: Risk of dumping syndrome
- Weight Loss Results: Patients can expect to lose 60 to 80 percent of excess weight within the first year to year and a half.
Gastric Sleeve
- Procedure: The surgeon removes a portion of the stomach, producing a tube-shaped stomach (sleeve).
- Recovery Time: 2 to 4 weeks
- Risks and Complications: Lower risk of dumping syndrome
- Weight Loss Results: Patients should expect to lose weight at a slower, steadier rate. In the first 12 to 18 months, they may lose 60 to 70 percent of excess weight.
Whether you select gastric bypass or gastric sleeve, it's important that you follow a strict post-surgery diet.
