GLP-1 Nausea, Vomiting and Constipation
Nausea, vomiting, diarrhea and constipation are among the most common adverse effects of incretin treatment. Symptoms are often most noticeable after starting or increasing a dose, but severe or persistent symptoms should not be normalized.

What to do
For nausea
Use smaller meals, avoid heavy or greasy foods, eat slowly and stop before feeling overly full.
For constipation
Review fluid intake, fiber tolerance, movement and other constipating medicines with the clinician.
For vomiting or diarrhea
Prioritize hydration and contact the office when symptoms persist, recur or interfere with medication and food intake.
When prompt medical guidance is important
- Repeated vomiting, blood or coffee-ground material
- Severe constipation with abdominal swelling, pain or vomiting
- Severe right-upper abdominal pain, fever or jaundice
- Symptoms of dehydration or acute kidney injury
Call 911 for severe breathing difficulty, loss of consciousness, stroke-like symptoms or another emergency.

Frequently asked questions
Can I use an over-the-counter remedy?
Ask the clinician or pharmacist because other conditions and medicines affect what is safe.
Should I eat more fiber immediately?
Fiber may help some patients but can worsen bloating or obstruction-like symptoms; increase thoughtfully.
When should the next dose be held?
The prescribing clinician should make that decision based on symptom severity and the product instructions.
