So you’ve gained some weight and don’t know what to do to turn the scale around. It happens, and were here to help! Here we will go through EXACTLY what could be causing weight gain after gastric sleeve surgery – and how to fix it!

There are a few main causes of weight gain after gastric sleeve surgery. 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.

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.

Average Appetite Overtime (How Your Appetite Increases)

All patients progressively increase their capacity for food over time. The more your body adapts to the new stomach size, neurohormonal changes occur and will adjust after gastric sleeve surgery.

For example, after gastric sleeve surgery patients 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.

The Most Common Reasons for Weight Gain

  • Medications: It is important to do research on your current medications if you are facing gastric sleeve weight gain.
  • Processed Foods: Artificially sweetened or unnaturally sweetened foods.
  • Lack of Physical Activity or Injury: Being active isn’t always enough. Even if you are currently active, you may need to become more active through exercise or working out.
  • Liquid Calories: Drinks that have a high amount of calories without providing a feeling of fullness (such as soda and juice).

Other Potential Causes of Gaining Weight After Gastric Sleeve Surgery

Strategy to Overcome Weight Gain

Some patients have to work a lot harder to lose weight and keep the weight off. Gastric sleeve surgery is not a perfect “fix-all” solution. It is a tool, and you can work with the tool or work against it.

  • Nutrition: What are your current eating habits?
  • Exercise: Be more active and start a new exercise routine.
  • Medications: Have you started gaining weight since you started a new medication? Speak with your doctor to discuss other alternatives.
  • Bariatric Revisional Surgery: These can be risky and patients tend to lose less weight with revision surgeries.

Stomach Stretching

Rather than the stomach “stretching”, patients can see an increase in capacity for food. By overeating, you are allowing your new stomach to stretch, 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 stretching with bad eating habits for long periods of time. The stomach is an elastic organ, making stomach stretching after gastric sleeve possible, but insignificant.
