Why do I get Stomach cramps and hot flushes after eating eggs, anything dairy and greasy foods?

Food allergies. And grease just does that you.

As others have mentioned, pescatarian. FYI: vegan=no animal merchandise whatsoever dietary vegan=won't devour honey, eggs, fish, milk, etc, however will put on silk, wool, and/or leather lacto- = will consume milk/merchandise ovo- = will devour eggs/merchandise pesca- = will consume fish/seafood pollo- = will not devour chook place all these in entrance of vegetarian while you get to the factor of being a pesca-pollo-lacto-ovo vegetarian, it's less complicated to claim "i do not consume crimson meat" there may be additionally fruitarian=no root greens, which directly contradicts the fifth-degree vegetarian who does not devour some thing that casts a shadow (for those w/o a humorousness, fruitarian is actual, fifth-level is the simpson's joke). Simply so , there's also a combination of those. I've family who follow the Jain eating regimen, so they don't devour root vegetables/eggs, but devour milk, since they're Indian and cows are theoretically not mis-dealt with.

Allergic reactions definitely I'd see a doctor

crohns, IBS or lactose intolerance
