Causes of Diarrhoea

Infection, inflammation, food poisoning, food allergy and colorectal cancer can cause diarrhea. Some food or drugs may also lead to diarrhea. Generally infection will lead to acute diarrhea and it will subside spontaneously within two to three days. One should consult a doctor if diarrhoea lasts for more than three weeks or is recurrent or blood is seen in the stool. Chronic diarrhoea may be due to unusual infection, colorectal cancer, and chronic inflammatory bowel diseases such as Crohn’s disease or ulcerative colitis.
