What causes diarrhoea?

Many events may cause abnormal functioning of the GI tract that in turn results in diarrhoea. The more common causes are described below. Diarrhoea can be acute or chronic. Acute diarrhoea means that it comes on suddenly and lasts a short time. The most common causes of acute diarrhoea are travellers` diarrhoea, gastroenteritis, food poisoning, overindulgence and stress. Chronic diarrhoea means that it goes on for a long time.

Travellers` Diarrhoea
Travellers` diarrhoea is caused by parasites or bacteria found in tap water and food in many parts of the world. When people travel to a new place, they are more likely to become sick because they lack protective antibodies that attack these germs. People who live in the region do not get diarrhoea as their bodies are accustomed to the germs.

Gastroenteritis
Gastroenteritis is an infection of the gut causing diarrhoea and sometimes vomiting and fever. The cause of gastroenteritis is usually a virus but it may also be bacteria especially in the case of food poisoning.

Overindulgence
Excessive consumption of certain foods and alcohol can result in diarrhoea.

Stress
Emotional stress and anxiety can sometimes causes diarrhoea as the bowel moves its contents too quickly. Once the stressful situation has passed, the diarrhoea usually stops.
