What is the typical weight loss range after sleeve gastrectomy at 1 year?

• A. Approximately 5-10%
• B. Approximately 10-15%
• C. Approximately 20-30%
• D. Approximately 40-50%

Answer: (C)

Sleeve gastrectomy typically yields a substantial but moderate amount of weight loss by one year, about one-fifth to one-third of initial body weight. In practice, that means most patients end up around 20–30% lighter at the 12-month mark. This happens because the procedure reduces stomach capacity, limiting how much food can be eaten, and it also lowers hunger signals through hormonal changes, helping sustain daily energy deficit over time. Weight loss tends to be fastest in the first several months and then slows as the year progresses, with outcomes highly influenced by adherence to diet, activity, and follow-up care. Very low percentages, like around 5–15%, are more characteristic of non-surgical weight loss methods or insufficient follow-up and support. Extremely high percentages, such as 40–50%, are not typical at one year for this procedure.
