How Much Weight Can You Lose After Gastric Sleeve?
Weight loss after gastric sleeve surgery varies from patient to patient. However, most individuals experience significant and measurable weight loss within the first year following the procedure.
Average Weight Loss Expectations
On average, patients lose approximately 60–70% of their excess body weight within 12 to 18 months after gastric sleeve surgery. The most rapid weight loss typically occurs during the first 6 months.
Weight Loss Timeline
Weight loss progresses gradually and steadily:
- First 3 months: Rapid initial weight loss
- 6 months: Noticeable physical and metabolic changes
- 12 months: Majority of excess weight lost
- 18 months: Weight stabilization phase
Factors That Affect Weight Loss Results
Several factors influence how much weight a patient can lose:
- Starting body weight and BMI
- Dietary compliance and portion control
- Physical activity and lifestyle habits
- Regular medical and dietitian follow-up
Long-Term Weight Management
Gastric sleeve surgery is a powerful tool, but long-term success depends on maintaining healthy habits. Patients who follow dietary guidelines and attend regular follow-up appointments are more likely to achieve sustainable results.
