Why it happens on GLP-1
These medicines cause the stomach to empty more slowly. Nausea can come when food sits in your stomach longer. This happens most often after big or fatty meals.

Wording from the Ozempic label
In these words, the label mentions nausea:
“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
- Sip ginger or peppermint tea that has no sweetener.
- After you eat, stay upright rather than lying down.
- Ask your prescriber about a nausea medicine to have on hand.
- Have smaller meals and stop eating when you feel full. These medicines slow the rate at which your stomach empties.
- Eat slowly. It takes some time before your brain notices you are full.
- Ease up on fatty, greasy and sugary foods, since they often bring symptoms on.
- If it does not ease, tell your prescriber. Your prescriber may suggest a different GLP-1 or slow the dose increases.
Before taking drugstore products, check them with the GLP-1 interactions checker.
