Crohn’s disease causes inflammation in the small intestine, which causes pain and can make the intestines empty frequently, resulting in diarrhea. Other complications of Crohn’s include blockage of the intestine, ulcers, arthritis, kidney stones, gallstones or other diseases of the liver and biliary system. Foodborne transmissions of E. coli, Listeria and Streptococcus have been linked to Crohn’s disease.
