Why it happens on Ozempic
These medicines slow down how quickly the stomach empties. Food remains in the stomach longer, which can cause diarrhea, especially after you eat a large or fatty meal.

What you can learn from the Ozempic label
The label mentions diarrhea in these exact words:
“majority of the reported events occurred in patients who experienced gastrointestinal reactions leading to dehydration such as nausea, vomiting, or diarrhea [see Adverse Reactions (6.1)].”

What helps, step by step
- Replace fluids and salts by drinking water and an electrolyte drink.
- For a while, choose soft, bland foods with little fiber.
- Reduce your intake of milk drinks, caffeine and alcohol.
- Discuss an anti-diarrhea medicine from the drugstore with your prescriber.
- Choose smaller meal portions and stop eating when you feel full. These medicines slow down how fast your stomach empties.
- Eat slowly. Your brain needs some time to notice that you are full.
- If it does not get better, tell your prescriber. Your prescriber may suggest a different GLP-1 or slow the dose increases.
Before you take any drugstore product, check it with the GLP-1 interactions checker.
