Why it happens on Rybelsus
These medicines slow the rate at which your stomach empties. Nausea can come on when food stays longer, especially after big or fatty meals.

What helps, step by step
- Sip tea made with ginger or peppermint, without sweetener.
- Once you eat, stay upright.
- Ask your prescriber about a medicine for nausea that you can keep on hand.
- Select smaller meals, and stop eating when you feel full. These medicines slow down how fast your stomach empties.
- Eat slowly. Your brain needs time to recognize when you are full.
- Limit fatty, greasy or sugary foods because they often cause symptoms.
- If it does not ease, tell your prescriber. A different GLP-1 may be suggested, or they may slow the pace of dose increases.
Before taking a drugstore product, check the GLP-1 interactions checker.
