Acid Reflux / GERD

Heartburn, acid taste in mouth, or burning sensation in the chest caused by stomach acid flowing back into the esophagus

Prevalence

5-15% of patients

Severity

Common

Category

Gastrointestinal

Why It Happens

Delayed gastric emptying increases the volume of food and acid sitting in the stomach for extended periods. This can increase pressure on the lower esophageal sphincter, allowing acid to reflux into the esophagus. Patients who already have GERD may experience worsening symptoms.

Timeline

Can occur at any point during treatment but is most common during dose escalation. May persist if eating habits are not modified. Pre-existing GERD may worsen initially.

Management Tips

1

Avoid eating within 3 hours of lying down or bedtime

2

Elevate the head of your bed 6-8 inches

3

Avoid trigger foods: spicy, acidic, fatty, chocolate, caffeine, alcohol

4

Eat smaller, more frequent meals

5

Wear loose-fitting clothing around the waist

6

Over-the-counter antacids or H2 blockers (famotidine) may help

7

Do not lie down immediately after eating

When to See Your Doctor

If heartburn is severe or occurs daily, you have difficulty swallowing, experience unexplained weight loss (beyond intended), vomit blood, or have chest pain (rule out cardiac causes first)

Acid Reflux / GERD FAQs

Can Ozempic cause acid reflux?

Yes. GLP-1 medications slow gastric emptying, which can increase the volume and pressure of stomach contents, leading to acid reflux. This is reported in 5-15% of patients in clinical trials.

Should I take a PPI with my GLP-1 medication?

Proton pump inhibitors (like omeprazole) can be used alongside GLP-1 medications if recommended by your doctor. There are no significant drug interactions, but long-term PPI use has its own considerations. Discuss with your healthcare provider.

Will acid reflux from GLP-1 medications go away?

Many patients see improvement as they adjust their eating habits (smaller meals, timing) and as the body adapts. If you had pre-existing GERD, it may require ongoing management. Weight loss from the medication can actually improve GERD long-term.

Talk to a provider about managing acid reflux / gerd

If acid reflux / gerd is affecting your quality of life, a qualified provider can adjust your dose or recommend management strategies.
