Weight Regain After Sleeve: Causes and When to Consider Revision

• The stomach gradually stretches over time, or the remaining stomach was large to begin with.
• Hunger hormones gradually return.
• Sweets and high-calorie drinks, grazing through the day, and bigger portions.
• Emotional eating or binge eating.
• Dropping out of follow-up and low physical activity.

1. Assessment first: a diet review with the dietitian, blood tests, and an endoscopy or imaging to see the current shape of the stomach.
2. Back to eating basics: protein first, drinks apart from meals, regular meals (see Eating after sleeve gastrectomy).
3. Medication: weight-loss injections may be used under medical supervision (see Injections or surgery?).
4. Revision surgery: for those who don't respond to the steps above, or when there is a clear anatomical cause or severe reflux.

• Conversion to a classic or mini gastric bypass: the most widely used option, often preferred when reflux comes with the regain.
• SADI-S: a conversion that relies more on reduced absorption and needs close vitamin monitoring.
• Re-sleeve: in selected cases with clear stretching of the stomach and no reflux.

The choice depends on the cause, diabetes, reflux and nutrition. Revision operations are more complex than the first operation and carry higher risks, including leaks, bleeding, narrowing and vitamin or protein deficiencies (especially after SADI-S), so they follow a full assessment.
