Is it a sugar allergy or IBS?

[Jessica]

My younger sister (12) gets diarrhea after eating anything that is sugary, like cereal, popsicles, ice cream and candy. Her stomach also begins to hurt as well. She has a nervous stomach and gets diarrhea very easily when she is nervous/worried. I think that she has irritable bowel syndrome, but my step-mom thinks it is just an allergy. I think that if it was an allergy, she would have more problems then just diarrhea, like a rash or she would get really sick. She has not gone to the doctor yet, but I am trying to talk my step-mom into taking her just to make sure it isn't anything too serious. Any help with this question would be greatly appreciated! Thank you!!!

IBS is a blanket name given to any kind of gastroentestinal disorder. If the Dr. can't find another diagnoses, he will call it IBS. There are prescription drugs that can help IBS like Donnatal, Lomotil, etc. I would recommend your sister go see a gastroenterologist. He can make her much more comfortable. There is no reason for her to live the way she is living. There are solutions. Good luck.
