On average, gastric sleeve results in the following excess weight loss:

  • Month 3: 30% of excess weight lost
  • Month 6: 50% of excess weight lost
  • Month 12: 70% of excess weight lost

See our Gastric Sleeve Before and After page for pictures of other gastric sleeve patients, including women, men, and celebrities.

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.

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 vBloc Therapy or AspireAssist, and long-term results are not applicable to the Gastric Balloon since it must be removed after 6 months.
