what could be going on with me

Since childhood, (23F) I’ve been very prone to food poisoning, especially after eating street food. These days, it doesn’t happen as often because I’ve learned what and where it’s safer to eat. However, it can still happen occasionally. Sometimes, after eating the same food as others, I may experience only mild symptoms like upper abdominal cramps or occasional vomiting, while others are unaffected

I’ve seen doctors multiple times and they’ve always said it’s food poisoning. I also had an ultrasound once and the doctor said everything looked normal

There is no food that I can say no matter where i eat I get vomiting, cramps or whatever from it
