Classification of diarrhoeal disease

Authoring team

Diarrhoea can be classified into two broad categories based on aetiological factors: infectious and non-infectious.

The most common cause of acute diarrhoea worldwide is infection (viruses, bacteria, and parasites). Most are acquired through the faecal-oral route, from contaminated water or food. Most infections are self-limiting or treated easily.

In non-infectious diarrhoea, a number of drugs are associated with this including antacids containing magnesium, anti-arrhythmics, antibiotics, anti-hypertensives, NSAIDs and antineoplastic agents. It may also occur as a result of inflammatory bowel disease, bowel ischaemia, and radiation injury.
