My son frequently has to run for a bathroom shortly after eating (mostly if it is away from home). He has irregular bowel movements, and in school, was running to the bathroom almost once a class period. He is being tested for crohns, celiace and ibd. The doctor put him on a no wheat, no art. flav, no art. color, no lactose and no fried foods. He is 16 years old. Now, he complains of being tired, weak, headace at the base of his head, his knees shake and give out on him. All this is following an unknow mass surrounding his testicle (surgery removed the mass) in January. Then in March, he began losing his hair (head, arms, legs, eyelashes, brows, private areas). Now this digestive issue. Does anyone see a familiar flow of symptoms?
