Why this happens while you are taking Wegovy
How fast the stomach empties slows down with these medicines. Because food stays in your stomach longer, vomiting can occur, especially after big or fatty meals

What the Wegovy label says
Here, the label mentions vomiting word for word:
“most common adverse reactions leading to discontinuation were nausea (1.8% versus 0.2%), vomiting (1.2% versus 0%), and diarrhea (0.7% versus 0.1%) for WEGOVY and placebo,”

What helps, step by step
- Drink water in small amounts often so you do not get dehydrated.
- After you eat, stay upright rather than lie down.
- Ask your prescriber about a nausea medicine you can keep on hand.
- Choose smaller meals and stop eating once you feel full. These medicines slow down how quickly your stomach empties.
- Eat slowly. Your brain needs time to recognize that you feel full.
- Fatty, greasy, and sugary foods often cause symptoms, so limit how much you eat.
- If symptoms fail to ease, tell your prescriber. Your prescriber may slow how quickly doses increase, or suggest a different GLP-1 medicine.
Before taking anything from the drugstore, use the GLP-1 interaction checker to check it.
