As you can see, most patients lose weight very quickly following surgery. You should start to notice significant weight loss after just a few weeks.
Why does gastric sleeve surgery work so well?
- Reduced stomach size makes patients feel full sooner after eating
- Removed portion of the stomach results in fewer hunger-causing hormones secreted, causing patients to feel less hungry generally
Gastric Sleeve Bad Results: Avoiding Weight Regain
If you’re able to maintain the right diet and exercise habits, most of the weight you lose will stay off. However, gastric sleeve results over the long-term usually include at least some weight regain:
- 3 years: 60% of excess weight kept off
- 5 years: 55% of excess weight kept off
- 8 years: 56% of excess weight kept off
- 11 years: 63% of excess weight kept off
Weight regain is usually due to patients not sticking with the proper routine. As a result of overeating, the smaller stomach created during the sleeve procedure can stretch out. This allows the patient to eat more and regain weight.

Weight Loss: Gastric Sleeve Vs. Other Procedures
- Best Weight Loss After 1 Year
