Everytime i eat i have diarrhea, with pieces of food in it- loss appetite-been goin on for 4 months now- had ct, bloodwork & upper gi- all clean- idea?

Further w/u needed: Hi, based on the constellation of symptoms ; signs u have, further work up would be required. Please see a GI particularly if you are loosing weight, have diarrhea at night, abdominal pain, anemia, blood in the stool. Celiac disease, lactose intolerance, inflammatory bowel disease(crohns), ibs are among the few diagnoses that need to be ruled out. Hope this helps.
