Gastric sleeve surgery makes patients eat less by reducing hunger-causing hormones as well as feel full faster by reducing stomach size and creating a restriction. Most overweight and obese people undergo weight loss surgery because diet and exercise aren’t maintaining any significant long-term results.
Sleeve surgery helps patients lose excess weight quickly, efficiently, and permanently. However, in about 30% of the cases, gastric sleeve patients have inadequate weight loss, weight regain or develop upper GI problems requiring revisional surgery .
The main reasons that sleeve patients regain excess weight are loss of restrictions and/or change in their eating habits.
So you’ve gained some weight and don’t know what to do to turn the scale around. It happens, and we’re here to help! Here we will go through EXACTLY what could be causing weight gain after gastric sleeve surgery – and how to fix it!
Whether you are one month, one year, or more years after surgery this article should help prevent weight gain from worsening.
Gastric Sleeve and Weight Gain
Regaining weight occurs in a small patient population starting anywhere from 18 months to 6 years after gastric sleeve surgery. Weight regains range from a small portion of excess weight to almost the entire weight loss.
There are a few main causes of weight gain after bariatric surgery, specifically Laparoscopic Sleeve Gastrectomy (LSG). It’s not a question of if the appetite will return, it’s about planning and preventing overeating when the body starts to increase food intake. So just remember, you are not alone.
Another possible scenario for insufficient weight loss and regain is the surgeon’s technical errors, such as:
- Incorrect calibration with a bougie
- Incomplete dissection of the gastric fundus
The amount of weight you lose will eventually, or abruptly come to a halt. Gastric sleeve weight gain will occur eventually. Whether you reach your goal weight or not, it is bound to happen at one point in time or another.
Change your diet and lifestyle
How Your Appetite Increases Over Time
All patients progressively increase their capacity for food. Your body adapts to the new stomach size, neurohormonal changes occur and will adjust after gastric sleeve surgery.
For example, after gastric sleeve surgery, patient’s appetites tend to increase as shown below.
- 1 month: 2 to 3 bites per meal
- 6 month: 3-4 ounces of food per meal
- 1 year: 6 ounces per meal
- 3 year: 8 ounces per meal
- 5+ year: 8+ ounces per meal
The goal is to avoid increasing your stomach’s capacity more than it will naturally. Remember, the slightest boost of eating more food can grow exponentially over the course of a few weeks and cause weight gain after gastric sleeve surgery.

Rather than your sleeve stomach “stretching”, patients can see an increase in capacity for food. By overeating, you are causing loss of restriction, which can result in weight gain or increased capacity for food.
After gastric sleeve surgery, the stomach size holds roughly 2 to 3 ounces of food as opposed to the average stomach holding 40 ounces of food. It is a common misconception that the smaller stomach is capable of stretching back to its original size. This is false, but patients may encounter slight dilation with bad eating habits for long periods of time. The stomach is an elastic organ, making stomach stretching after gastric sleeve possible, but insignificant.
