question: Hello, our 10 year old son eats like a horse until appx 2 months ago. Now he says he is not hungry most of the time. When he does eat he may have to leave the table to go to the bathroom and sometimes he has diarrhea. He says he can t explain it but seems like his stomach feels bloated or small pains. When he first wakes up he has to go straight to the bathroom. He has us concerned. Thanks for your help.
