What is the Success Rate for Bariatric Surgery?

The success rate of bariatric surgery, also known as weight loss surgery, can vary depending on the type of procedure, the patient’s health status, and other factors. Generally, weight loss surgery is considered successful if the patient achieves and maintains a significant reduction in body weight and experiences improvement in obesity-related health conditions.

Here are some general success rates for the most common types of weight loss surgery:

• Gastric bypass surgery: Studies have shown that gastric bypass surgery can result in weight loss of 60-80% of excess body weight within the first year after surgery. Long-term success rates (10 years or more) have been reported to be around 50-60%.
• Sleeve gastrectomy: Sleeve gastrectomy is a procedure that involves removing a large portion of the stomach to create a smaller, tube-shaped stomach. Studies have shown that sleeve gastrectomy can result in weight loss of 50-70% of excess body weight within the first year after surgery. Long-term success rates are still being studied.
• Laparoscopic adjustable gastric banding: This procedure involves placing a band around the upper part of the stomach to create a small pouch. Studies have shown that laparoscopic adjustable gastric banding can result in weight loss of 40-50% of excess body weight within the first year after surgery. Long-term success rates (10 years or more) have been reported to be around 30%.

It’s important to note that weight loss surgery is not a guarantee of success, and patients must commit to making long-term lifestyle changes to achieve and maintain their weight loss goals. Working with a healthcare team, including a dietitian and mental health professional, can also improve the chances of success.
