Why Do I Have GERD After Taking GLP-1 (Ozempic and Semaglutides)?
|

Time to read 4 min
GLP-1 receptor agonists like Ozempic and Wegovy have changed how we manage type 2 diabetes and obesity. But for some people, they trigger a less welcome side effect: GERD. GERD, or gastroesophageal reflux disease, is a chronic condition in which stomach acid repeatedly flows back into the esophagus. This reflux can lead to symptoms such as heartburn, regurgitation, bloating, and discomfort after meals.Â
In this article, we explore why GLP-1 medications can cause GERD and provide strategies to help manage it without interrupting your treatment.

Why GLP-1 Drugs Cause GERD Symptoms?
GLP-1 drugs (GLP-1 receptor agonists) are designed to improve blood sugar control, support weight loss, and slow gastric emptying. Common examples include semaglutide (Ozempic, Wegovy). While these effects are beneficial for metabolic health, they can also lead to GERD in some individuals.
1. Delayed Gastric Emptying
GLP-1 drugs delay the rate at which food leaves your stomach, a major reason they curb appetite and control blood sugar. But when food stays in the stomach longer, it can cause increased pressure, leading to reflux symptoms and persistent GERD, especially after meals.
2. Increased Intragastric Pressure
As the stomach remains full for longer due to delayed gastric emptying, pressure builds within the gastric cavity. This pressure can push stomach contents upward, particularly in individuals with pre-existing GERD or reduced esophageal tone. The result is a higher risk of reflux symptoms such as heartburn and regurgitation, especially after meals or when lying down.
3. Reduced Meal Frequency and Larger Portions
GLP-1 medications suppress appetite. As a result, some people eat fewer meals per day but consume larger portions at once. These larger meals create more pressure in the stomach, heightening the likelihood of acid reflux and worsening GERD symptoms.
How to Manage GERD on GLP-1 Therapy
Fortunately, many people can control GERD symptoms through simple lifestyle modifications and targeted symptom management, without having to discontinue their GLP-1 medication.
1: Adjust Meal Size and Timing
Eat smaller, slower meals, ideally spread throughout the day.
Avoid eating within 2-3 hours of lying down.
Refrain from drinking large amounts of fluid during meals.
This approach reduces pressure on the stomach and minimizes acid reflux episodes.
2: Avoid Trigger Foods and Beverages
Certain foods are more likely to worsen GERD during GLP-1 treatment. These may include:
Citrus fruits and juices
Tomato-based sauces
Chocolate
Fried or fatty foods
Carbonated beverages
Caffeinated drinks
Peppermint
Instead, focus on:
Lean proteins (chicken, fish, tofu)
Non-citrus fruits (bananas, melons)
Cooked vegetables
Oatmeal or whole grains

If you're unsure what your triggers are, consider keeping a food and symptom diary to track your reactions over time. You can also take Claisen’s free quiz for personalized insights into your gut health.
3: Stay Upright After Meals
Avoid reclining or lying down for at least 2-3 hours after eating, as this gives gravity time to assist digestion and prevents acid from moving upward into the esophagus.
4: Sleep with Head Elevation
If acid reflux occurs at night, raise the head of your bed by 6-8 inches or use a wedge pillow. Elevation helps keep acid in the stomach, particularly if delayed gastric emptying is involved.
5: Review Your Injection Timing and Meal Patterns
Some people find GERD symptoms are worse when GLP-1 doses are taken on an empty stomach or close to large meals. With guidance from your provider, you may benefit from:
Changing the timing of your injection
Slowing your dose escalation
Adjusting your mealtime structure
6: Take Antacids or Acid-Suppressing Medications
Over-the-counter (OTC) and prescription drugs are available to treat GERD that work either by suppressing the production of stomach acid or neutralizing stomach acids. Common options include:
Calcium carbonate (e.g., Tums)
Alginate-based agents (e.g., Gaviscon)
H2 blockers (e.g., famotidine)
Proton pump inhibitors (PPIs) (e.g., omeprazole)
Important: Always consult your prescribing physician before adding any medication, as drug interactions and timing (especially with semaglutide) need to be carefully managed.
Key takeaways
GERD (gastroesophageal reflux disease) is a common side effect of GLP-1 medications due to slowed gastric emptying and increased stomach pressure.
Symptoms include heartburn, regurgitation, and bloating, especially after meals or at night.
Managing meal size, timing, and food choices can significantly reduce GERD episodes.
Talk to your provider before adding antacids or acid-reducing medications.

Is GERD a known side effect of Ozempic or Wegovy?
Yes. While not everyone experiences it, GERD is a recognized gastrointestinal side effect of GLP-1 receptor agonists like semaglutide.
Do I need to stop my GLP-1 medication if I get GERD?
Not usually. With the right changes to your eating habits and medical guidance, most people can manage GERD and continue treatment.
Can GERD go away as I adjust to the medication?
Yes. Many GI symptoms, including acid reflux, improve after 4-6 weeks as the body adapts to slower gastric emptying.
Can I take omeprazole or famotidine with GLP-1 medications?
Yes, but only under the direction of your healthcare provider. Acid-suppressing medications can be helpful, but their timing and compatibility with your treatment plan need to be considered.
