Is it normal to pee when you throw up?

Yes—vomiting can put sudden pressure on your bladder and make a little pee leak out. It can happen occasionally, especially if your bladder is full.
Throwing up makes your abdominal muscles squeeze hard, much like coughing or sneezing. That pressure can cause a small leak, and retching can also make it harder to hold your pee in the moment. It’s an embarrassing body quirk, but not unusual.
If it happens often, or you’re also leaking urine at other times, it’s worth mentioning to a healthcare professional; there may be ways to help.
