I am experiencing light pink stool, stomach cramps and diarrhea . had culture tests come back as no parasites or ova and no e coli. ?

Colitis: If the symptoms are only a few days old, a viral intestinal tract infection is likely and the pinkish stool color suggests very mild superficial rectal bleeding. For these symptoms treatment would be rest, drinking of adequate room temperature fluids and avoidance of harsh roughage in your diet. Kaopectate helps control diarrhea. If symptoms are more chronic, see a gastroenterologist for evaluatio

Good news so far: Your negative test results thus far are encouraging, but your persistent symptoms and concern warrant additional investigation. Ask your provider to keep looking, particularly since even light bleeding in association with symptoms described may signal an underlying inflammatory bowel disease.
