What is the expected weight loss percentage after sleeve gastrectomy?

Sleeve gastrectomy is a popular bariatric surgical procedure designed to promote significant weight loss in individuals with obesity. The expected percentage of total body weight loss after such a procedure typically averages around 60%. This procedure involves the removal of a substantial portion of the stomach, which both limits food intake and affects hormonal signals related to hunger and satiety.

After sleeve gastrectomy, patients generally experience rapid initial weight loss in the first few months, followed by a gradual stabilization in the subsequent years. Research and clinical studies have shown that most patients achieve an approximate weight loss of 50% to 60% of their excess body weight within the first year post-surgery, and this figure can be slightly higher for some individuals.

Choosing the 60% weight loss percentage as the expected outcome aligns with the broader understanding of the procedure's effectiveness in promoting long-term weight management compared to other behavioral and medical interventions for obesity. This expectation provides patients with a realistic outlook on potential results and underscores the importance of combining surgical intervention with lifestyle changes for optimal health outcomes.
