Do most people who have weight loss surgery regain their weight?

While some patients regain weight after weight loss surgery, it is not inevitable. Many factors contribute to weight regain, but with the right approach, it can be managed and prevented. After bariatric surgery, patients typically lose 60% of their excess weight in the first 1-2 years. However, some may experience a gradual regain, usually around 20-25% of the weight lost over a ten year period.

Weight regain can happen for several reasons, including changes in diet and exercise habits, as well as the natural expansion of the stomach pouch over time. Additionally, psychological factors such as stress eating or emotional eating, or physical changes like hormonal fluctuations can also contribute to weight gain.

Who is at risk for weight regain? 

Certain groups may be more likely to experience weight regain, including younger patients, those with physical conditions that limit activity, or individuals who experience emotional challenges after surgery.

How can weight regain be prevented? 

To prevent weight regain, it’s essential to maintain healthy eating habits and a consistent exercise routine. Follow-up care with your bariatric team and participation in support groups can also provide vital guidance and motivation. Here are some key strategies:

• Eat smaller, regular meals and avoid overeating or snacking.
• Exercise consistently to maintain muscle mass and keep metabolism active.
• Join a support group to stay connected with others on a similar journey.

How much weight is regained? 

While weight regain after bariatric surgery is common, the amount of weight regained tends to vary over time. On average, patients may experience a gradual increase in weight in the years following surgery. On average patients may be expected to regain 20-25% of the weight lost in the first two years after surgery over a ten-year period. However, a lot of our surgery patients follow up with the clinic over the long term and transition into a medical weight loss program. Since the availability of and growing research about maintaining weight loss with medication like GLP-1’s, more patients have been successful at keeping off unwanted weight after surgery.
