Note: I am not la looking for medical advice. Do not remove my post.

I had a terrible stomachache last night and ended up in hospital. I threw up once at home and I only puked the food I had eaten 20 min before. Later at the hospital I threw up what I had eaten for lunch. Why the first time I didn’t threw up a mix of both. How does the stomach selects what to throw up?

My wife always says that the body is wise and only expels what hurts you. Kinda right to think that way but how does it work.

It’s a communication between the immune system, the nervous system, and the gut. If the toxin is biological based, like a foodborne toxin, the immune system employs a certain kind of white blood cell that releases substances that tell your gut to contract and expel. This causes vomiting.
