How Much Weight Can I Lose with Bariatric Surgery?

Weight loss surgery can be an invaluable and life-saving treatment for individuals struggling with obesity and morbid obesity. At our Dallas practice, Dr. Hossein Bagshahi performs a wide range of laparoscopic, minimally invasive, and robotic-assisted procedures to help at-risk patients achieve a safer and healthier weight. While the exact amount of weight loss possible depends on the type of procedure performed and your commitment to maintaining a healthier lifestyle, our team has provided a brief primer on the average percentages of weight loss associated with some of the most frequently performed bariatric surgeries:  

• Duodenal Switch: Duodenal switch surgery generally offers the highest rate of weight loss, both immediately after surgery and in the long-term future. Most patients lose at least 50 percent of their excess body weight, with the greatest amount of weight loss reaching up to 85 percent. This can be particularly beneficial for individuals affected by diabetes, high cholesterol, or other obesity-related medical conditions. 
• Gastric Sleeve: With the gastric sleeve procedure, patients typically lose approximately 66 percent of their excess weight within 12 to 18 months. By reducing the size of the stomach, a gastric sleeve can restrict the amount of food consumption possible and help patients better manage their appetite.  
• Gastric Bypass: Also called a “Roux-en-Y” procedure, gastric bypass surgery allows individuals to lose an average of 50 percent of their excess weight within six months. This treatment option can yield effective long-term weight loss for good surgical candidates. 

The list above can give you a good idea of the types of results possible after bariatric surgery, but your commitment to making positive lifestyle changes will ultimately determine the quality and longevity of weight loss achieved. 

It’s important to speak to a board-certified weight loss surgeon about your treatment options to determine the best procedure to help you obtain a healthier lifestyle. Don’t hesitate to contact Dr. Hossein Bagshahi to schedule an initial consultation, where you can discuss the most effective treatment options for your concerns.
