For more information about what to expect after gastric sleeve surgery, see the following pages:

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
  • 3rd Best Weight Loss After 5 Years

Compared to the other widely performed types of weight loss surgery, gastric sleeve results in the most excess weight loss after 1 year. Gastric sleeve results after 5 years place it 3rd long-term among all procedures.

No long-term studies exist for AspireAssist and long-term results are not applicable to the Gastric Balloon since it must be removed after 6 months.
