How can I fix my acid reflux after gastric sleeve surgery?

Written by Amanda A. Kostro Miller, RD, LDN and medically reviewed by Dr. Stephen Boyce, MD

If you suffered from acid reflux before gastric sleeve surgery, then you may be unpleasantly surprised that acid reflux is still something you will have to deal with.

In this article, we’ll talk about why acid reflux still occurs after surgery and what you can do to make it better. We’ve even included a 1-Day meal plan to help you get started with managing your acid reflux.

What is acid reflux?

A normal stomach without acid reflux and a stomach with acid reflux

Acid reflux. GERD. Heartburn. You may see these terms used interchangeably, but they have medically different definitions.

Acid RefluxGERDHeartburn
A condition in which stomach acid bubbles up into the esophagus. This occurs from a weak sphincter muscle at the junction of the stomach and esophagus. Called the lower esophageal sphincter (LES), its job is to keep food and acid in the stomach.Chronic and/or severe acid reflux. It’s diagnosed when someone has acid reflux at least twice per week along with confirmation from other exploratory measures. GERD has the potential to cause inflammationA symptom of acid reflux and GERD. It’s described as a burning or painful sensation in the chest, esophagus and throat.

Causes and risk factors for these conditions include:

  • Weakness in the LES
  • Certain medications like antidepressants and NSAIDs
  • Being overweight or obese*
  • Hiatal hernia
  • Pregnancy
  • Drinking alcohol*
  • Smoking*

*Controllable risk factors

Risk factors for Acid Reflux GERD and Heartburn

There are some acid reflux risk factors that you can’t control. However, modifying controllable risk factors (along with our tips below) can help you manage acid reflux.

Why is my acid reflux worse after gastric sleeve surgery?

While some types of bariatric surgeries are known to improve acid reflux, gastric sleeve may not be one of them.

Some research shows that gastric sleeve surgery may increase acid reflux presence. Why?

Gastric sleeve procedures can decrease the pressure around the LES, making it weak. Couple that with increased pressure in the stomach when stomach size is reduced during surgery.

The possibility of developing acid reflux should be considered before consenting to a gastric sleeve procedure.

Gastric sleeve and GERD

Management of GERD and acid reflux is a huge focus in the bariatric surgery population. Being overweight or obese may increase your risk of acid reflux, GERD and further complications compared to someone of a healthy weight (3-4).

Here are other reasons why acid reflux may be so prevalent in the obese population:

  • Pressure on the stomach due to belly fat
  • Consumption of large meals that lead to stomach distention
  • Diets high in fatty foods (i.e. fast food, fried food)
  • Sedentary lifestyle
  • Presence of hiatal hernia

Effects of acid reflux

Acid reflux affects quality of life, sleep and may lead to food aversions. It can also cause inflammation in the esophagus. Cell damage in your esophagus can lead to Barrett’s esophagus, ulcers or cancer.

When a patient continues to have acid reflux (or gets it post-surgery), this adds undue stress to an already overwhelming time.

GERD and acid reflux can be relieved with weight loss, but if weight loss is gradual or never occurs, patients may continue to deal with symptoms months or years after surgery.

Some patients even consider gastric sleeve revision with a Roux-en-Y gastric bypass. Another option is fundoplication surgery where part of the stomach is wrapped around the LES to strengthen it.

Fundoplication surgery to alleviate GERD after gastric sleeve surgery

It’s important that you and your healthcare team explore all bariatric surgery options and the long-term effects of each.

Gastric sleeve and hiatal hernia

While it may seem that gastric sleeve surgery isn’t a reliable way to reduce acid reflux, one small study found that having a gastric sleeve procedure with hiatal hernia repair might be beneficial for GERD.

However, other research indicates that having a hiatal hernia repair with gastric sleeve surgery did not provide significant improvements.

What’s even more important is what happens to the hiatal hernia and GERD relationship after surgery. A 2020 study found that people who experience GERD after a gastric sleeve and hiatal hernia repair may be at higher risk of getting another hiatal hernia.

So, frequent acid reflux symptoms post-surgery should be brought up with your doctor.

How to fix acid reflux after gastric sleeve surgery

There are 3 main ways to relieve acid reflux: medications, dietary habits and behavioral changes:

  1. Medications
  2. Dietary habits
  3. Behavioral and Lifestyle changes
Ways to fix acid reflux after gastric sleeve surgery

You may find that one of these methods works great, but you may get more benefit if you include all methods.

Medications for acid reflux

  • Antacids neutralize stomach acid. Ask your doctor which antacids are appropriate for you.
  • H2 blockers work to reduce stomach acid before it forms.
  • Proton pump inhibitors also work to reduce stomach acid but are usually stronger and faster than H2 blockers.

Dietary habits for acid reflux

  • Reduce or avoid common acid reflux trigger foods. These include alcohol, tomato products, chocolate, coffee, spicy food, carbonated drinks, peppermint, greasy foods and fatty foods.
  • Reduce or avoid personal trigger foods that you’ve noticed give you trouble.
  • Avoid drinking liquids with meals or snacks. Eat your meal and then wait at least 30 minutes before consuming liquids.
  • Eat small meals, rather than large meals, to prevent stomach distension
  • Avoid eating late at night, especially if you’re about to lie down.

Behavioral changes for acid reflux

  • Quit smoking.
  • Wear loose clothing.
  • Avoid lying down right after eating.
  • Keep your head raised at least 6 inches when sleeping or lounging.
  • Continue your weight loss eating and exercise plan. Losing weight can help reduce acid reflux.

1-Day meal plan to reduce acid reflux symptoms

Your healthcare team may have specific dietary guidelines for you, so do your best to follow them.

  1. Size of meals and drinks: You may need to consume meals 1-2 Tbsp at a time and gradually increase.
  2. Texture: Ask your doctor or Registered Dietitian if you need to blend, puree or dice your food. Texture will be dependent on how long ago your gastric sleeve surgery occurred.
  3. Portions to continue weight loss: Ask for guidance on the exact right portions for your needs.

  1. I had gastric sleeve in 2019. Since then I have developed bad reflux that is with me all day and sizzles in my chest all night. I have lost 12 kg from not being able to eat. I have been seeing my doctor for the past year trying to work out why I couldn’t eat and felt awful every day. Since then I have spoken to my specialist who told me it is often related to the sleeve. I didnt have it before the sleeve and I dont wish it on anyone. I wasn’t really aware of it until after the sleeve. Its ruined my life and puts a strain on my family. My specialist is now recommending a gastric by pass but I really dont want more surgery. So be aware.

  2. This article was helpful. I had sleeve surgery and I’m experiencing acid reflux.
    I noticed having less ginger can help. do not chose chocolate protein shakes. try not to drink acidic protein water. Coconut and watermelon flavor seems work well. Drink nonfat lactose-Free milk.
