Steps that help
- Have ginger or peppermint tea without sweetener, and sip it.
- After you eat, stay upright rather than lying down.
- Ask your prescriber about a nausea medicine to keep on hand.
- Have smaller meals and stop eating when you feel full. These medicines make the stomach empty more slowly.
- Eat at a slow pace. It takes time for your brain to register that you are full.
- Cut back on foods that are fatty, greasy and sugary, since those often set symptoms off.
- If it does not let up, tell your prescriber. They may increase the dose more slowly, or suggest another GLP-1.
Check any drugstore product with the GLP-1 interactions tool before you take it.
