Hi. Thanks for your query. Noted the history about your daughter and understood the concerns. Diarrhea with pain in abdomen followed by orange colored urine needs urgent following things: Consult the Pediatrician for clinical evaluation, examination and investigations. Tests of stool: Routine, microscopy and occult blood. Tests of blood for CBC, culture and sensitivity, urea and creatinine. Tests of urine for routine, microscopy, culture and sensitivity. Ultrasonography of abdomen. Get all these things done so that a proper diagnosis and management can be done. Do not treat anything at home. Give plenty of fluids orally.
