Which weight loss range is expected after sleeve gastrectomy at 1 year?

• A. 20-30%
• B. 0-5%
• C. 40-50%
• D. 60-70%

Answer: (A)

Weight loss after sleeve gastrectomy at about one year is typically around a quarter of the starting body weight when measured as total body weight loss. The procedure reduces stomach size and promotes satiety, leading to steady weight loss over the first year. In practice, most patients fall in the roughly 20-30% range for total body weight lost at 12 months. Expressed as excess weight loss, the numbers are higher (often around 50-60%), but the question’s range reflects total body weight loss, which is why 20-30% is the best fit. The other ranges are too low or too high for a typical one-year outcome.
