What is gastroparesis?

Gastroparesis is a condition in which the stomach empties more slowly than normal. In severe cases, it is sometimes called stomach paralysis. Food stays in the stomach longer than it should, causing symptoms like nausea, vomiting, bloating, and feeling full after eating very little.

Can GLP-1 medications cause gastroparesis?

GLP-1 medications like Ozempic, Wegovy, Mounjaro, and Zepbound slow stomach emptying on purpose. This is part of how they reduce appetite and help with weight loss. For most people, this delayed emptying is mild and temporary. However, some individuals experience symptoms that look like gastroparesis.

It is important to understand that many people with these symptoms may have gastroparesis-like symptoms rather than true, diagnosed gastroparesis. Confirmed cases of GLP-1-induced gastroparesis appear to be very rare, but they have received significant attention in lawsuits and media reports.

How common is gastroparesis with GLP-1s?

True gastroparesis is rare. Studies estimate it occurs in roughly 10 to 40 people per 100,000 in the general population. By mid-2025, only a small number of cases had been reported in FDA adverse event databases for semaglutide and tirzepatide.

More commonly, patients experience delayed stomach emptying symptoms such as nausea, early fullness, and bloating. These symptoms usually improve as the body adjusts to the medication or with dose adjustments.

Symptoms of GLP-1 gastroparesis

• Severe nausea and vomiting
• Feeling full after only a few bites
• Bloating and abdominal pain
• Foul-smelling burps
• Heartburn or acid reflux
• Weight loss and malnutrition
• Symptoms that do not improve after stopping the medication

Who is at higher risk?

People at higher risk of gastroparesis symptoms include:

• People with diabetes, especially long-standing diabetes
• People with a history of gastroparesis or other GI disorders
• People taking higher doses of GLP-1 medications
• People who eat large, high-fat, or high-fiber meals

What to do if you think you have gastroparesis

If you have severe or persistent symptoms, contact your healthcare provider. They may order tests such as:

• A gastric emptying study
• Upper endoscopy
• Blood tests and imaging

Do not stop your medication without medical guidance. Your provider may lower your dose, switch medications, or recommend treatment.

How to reduce gastroparesis-like symptoms on GLP-1s

• Eat small, frequent meals
• Choose soft, low-fat, low-fiber foods during flares
• Chew food thoroughly and eat slowly
• Stay upright for at least 2 hours after eating
• Avoid carbonated drinks and alcohol
• Drink fluids between meals instead of with meals
• Ask your provider about dose adjustments

When to seek emergency care

Seek urgent medical care if you experience:

• Persistent vomiting and inability to keep fluids down
• Severe, unrelenting abdominal pain
• Signs of dehydration, such as dark urine or dizziness
• Vomiting blood or material that looks like coffee grounds
• Unintentional rapid weight loss

Frequently asked questions

Will gastroparesis go away if I stop GLP-1s?

In most cases, delayed stomach emptying improves after stopping the medication. Some cases may take weeks or months to fully resolve.

Are Ozempic and Wegovy more likely to cause gastroparesis than Mounjaro?

There is no clear evidence that one causes gastroparesis more than another. Both drug classes slow gastric emptying.

Can I take GLP-1s if I already have gastroparesis?

GLP-1 medications are generally not recommended for people with existing gastroparesis.

Is gastroparesis from GLP-1s permanent?

Most cases appear to be reversible, but ongoing research is evaluating long-term outcomes.

Should I avoid GLP-1s because of gastroparesis risk?

Serious gastroparesis is rare. For most people, the benefits of GLP-1s outweigh the risks, but individual medical history matters.

Conclusion

True gastroparesis from GLP-1 medications appears to be rare, but digestive symptoms like nausea, bloating, and early fullness are common and often temporary. Understanding the warning signs and working closely with a provider can help you use these medications safely.
