Bad stomach pain after eating protein

[clala]

The past month my brother has gotten a terrible stomach ache after eating anything with protein in it, even eggs and chicken make his stomach hurt. He has always eaten extremely healthy and works out every day. When this happens he becomes also really pale. Does anyone know what this could be?

Thank you! I told him to call his doctor tomorrow so Im hoping he will schedule and apt. But yes he ate beans last night and it was the same thing

Welcome to the gastroenterology community!  I would recommend he see a doctor about this.  Does this happen with all types of protein (like peanut butter or beans)?
