What is the cause?

Written by : DoctorNDTV Team

  • Diarrhoea may be caused by a temporary problem, like an infection, or a chronic problem, like an intestinal disease. A few of the more common causes of diarrhoea are bacterial infections. Several types of bacteria, consumed through contaminated food or water, can cause diarrhoea. Common types include Campylobacter, Salmonella, Shigella, and Escherichia coli.
  • Viral infections: Many viruses cause diarrhoea, including rotavirus, Norwalk virus, cytomegalovirus, herpes simplex virus, and viral hepatitis.
  • Food intolerances: Some people are unable to digest a component of food, such as lactose, the sugar found in milk.
  • Parasites can enter the body through food or water and settle in the digestive system. Parasites that cause diarrhoea include Giardia lamblia, Entamoeba histolytica, and Cryptosporidium.
  • Reaction to medicines, such as antibiotics, blood pressure medications, and antacids containing magnesium.
  • Intestinal diseases, like inflammatory bowel disease or coeliac disease.
  • Functional bowel disorders, such as irritable bowel syndrome, in which the intestines do not work normally.
  • Some people develop diarrhoea after stomach surgery or removal of the gallbladder. The reason may be a change in how quickly food moves through the digestive system after stomach surgery or an increase in bile in the colon that can occur after gallbladder surgery.
  • In many cases, the cause of diarrhoea cannot be found. As long as diarrhoea goes away on its own, an extensive search for the cause is not usually necessary.
  • People who visit foreign countries are at risk for traveller’s diarrhoea, which is caused by eating food or drinking water contaminated with bacteria, viruses, or, sometimes, parasites. Traveller's diarrhoea is a particular problem for people visiting developing countries
