If you’ve recently started Wegovy, Ozempic, or another GLP-1 medication for weight loss or diabetes management, you might be experiencing an unwelcome companion on your health journey: severe heartburn. This acid reflux can be more intense than what you’ve experienced before, leaving many patients frustrated when standard remedies like Tums or Pepcid fail to provide relief. At Klarity Health, we’re seeing many patients struggle with this exact issue, which is why we’ve created this comprehensive guide to understanding and managing semaglutide-related heartburn effectively.
GLP-1 receptor agonists like semaglutide (Wegovy, Ozempic) and tirzepatide (Mounjaro) work partly by slowing gastric emptying – the rate at which your stomach empties its contents into the small intestine. This mechanism helps you feel fuller longer, but it comes with digestive consequences:
This combination creates the perfect storm for persistent heartburn that feels resistant to conventional treatments.
Many patients report limited success with traditional heartburn remedies when taking GLP-1 medications. Here’s why:
For many patients on GLP-1 medications, proton pump inhibitors (PPIs) have emerged as the most effective solution for managing persistent heartburn. Here’s what makes them different:
PPIs like omeprazole (Prilosec), esomeprazole (Nexium), and pantoprazole (Protonix) work by:
| Treatment | Mechanism | Duration | Effectiveness for GLP-1 Users | Availability ||———–|———–|———-|——————————-|————-|| Calcium Antacids (Tums, Rolaids) | Neutralizes existing acid | 30-60 minutes | Low-Moderate | OTC || H2 Blockers (Pepcid, Tagamet) | Reduces acid production | 4-8 hours | Moderate | OTC & Prescription || PPIs (Prilosec, Omeprazole) | Blocks acid pumps | 24+ hours | High | OTC & Prescription || Alginates (Gaviscon) | Forms protective barrier | 4 hours | Moderate | OTC || Combination Approaches | Multiple mechanisms | Varies | High | Varies |
Many Klarity Health patients have found success with a proactive approach to managing GLP-1-related heartburn:
Some healthcare providers recommend starting a PPI like omeprazole before heartburn symptoms develop, especially if you have a history of acid reflux. This preventative approach has helped many patients avoid developing severe symptoms altogether.
‘I recommend that my patients who are starting semaglutide consider taking omeprazole 20mg daily for the first month, even before experiencing symptoms,’ notes one Klarity Health provider. ‘We’ve seen this significantly reduce the likelihood of developing severe heartburn.’
While medication is often necessary, these additional strategies can help:
If you’re experiencing persistent heartburn while taking semaglutide, tirzepatide, or another GLP-1 medication, it’s important to discuss your symptoms with your healthcare provider. They can:

Severe heartburn is a common side effect of GLP-1 medications, but it shouldn’t prevent you from benefiting from these powerful treatments. For most patients, a proactive approach using PPIs like omeprazole provides effective relief where standard antacids fall short.
Work closely with your healthcare provider to find the right solution for your specific situation, and remember that sometimes managing side effects requires a more targeted approach than over-the-counter remedies can provide.
For many patients, heartburn symptoms are most pronounced during the first 4-8 weeks of treatment or after dose increases. However, some patients may experience ongoing symptoms that require long-term management.
Most healthcare providers consider this combination safe, but always consult with your doctor about potential interactions and appropriate duration of PPI therapy. PPIs are generally not recommended for indefinite use without medical supervision.
While dose reduction might help with symptoms, it could also reduce the effectiveness of your treatment. Consult with your healthcare provider before adjusting any medication dosages.
Seek immediate care if you experience severe chest pain, difficulty swallowing, shortness of breath, or if your heartburn is accompanied by vomiting, especially with blood.
While some patients report mild relief from natural approaches like ginger tea or aloe vera juice, these remedies alone are rarely sufficient for the severe heartburn associated with GLP-1 medications.
