Nausea on a GLP-1
Quick answer
Nausea is one of the most common side effects in the first weeks and after a dose increase. For most people it eases with time.
What often helps
- Eat small portions, several times a day.
- Stop when you feel satisfied, even if there's food left on the plate.
- Go easy on fried and very fatty foods in the days after your shot.
- Sip water in small amounts through the day.
- Cold or room-temperature foods often go down easier.
When to get medical care
- Vomiting that keeps coming back for more than a day.
- You can't keep fluids down.
- If it's severe, lasts more than a few days or gets in the way of eating and drinking, talk to your doctor or care team.
In an emergency, call 911 or go to the nearest emergency room.
