Diarrhea is the single symptom that all inflammatory bowel ‘diseases’ have in common. People suffering with IBS/Irritable Bowel Syndrome-Colitis-UC/Ulcerative Colitis-Crohn’s ‘disease’ all experience either periodic or urgent diarrhea usually to some degree daily. This can be managed short term with otc meds like Imodium or by eating very restrictive diets. But—it will never go away w/o the proper treatment.
