When i eat or even drink water (sometimes) my stomache gets warm and burns, it gets very bloated. i am eating vegan now what is going on with me?

It's hard to say...: If this is a recent dietary change, your digestive system might not have adjusted to it. Vegan diets are high in fiber and beans & legumes as a protein source. It may take a while for the enzymes and healthy bacteria that process these foods to up-regulate. Alpha galactosidase (Beano) supplement may help. However, if, after a couple of weeks, u still have this problem, please see a doctor!
