Know More About Diarrhoea and Its Causes

Diarrhoea is a common digestive disorder that virtually all people will suffer at some stage during their lives. The definition of diarrhoea varies but it can generally be taken to mean increased stool water causing an increase in stool frequency or the passage of soft stools. Passage of greater than 3 stools per day or a stool volume of greater than 200 mL suggests the diagnosis of diarrhoea.

Diarrhoea is called acute if lasts for less than two weeks or chronic if it lasts for greater than 4 weeks. Diarrhoea can occur in virtually any person regardless of their age and general health. Diarrhoea can range from a mild discomfort to a severe and life threatening illness due to the risks of dehydration. In fact diarrrhoeal diseases are one of the top causes of death worldwide and it becomes particularly common in developing countries with poor food practices and hygiene.
Children and the elderly are particularly prone to dehydration secondary to diarrhoea. However, the great majority of cases of diarrhoea follow short courses which don’t really require specific diarrhoea treatment to resolve.

Mechanisms for the formation of Diarrhoea

Diarrhoea basically develops when there is a defect in the absorptive mechanism working in the intestines. This may be due to damage to the mucosa (lining of the bowel) from infections or inflammation or excess secretion of fluid and electrolytes from particular toxins (e.g. cholera). Sometimes there may be too much sugary material in the lumen of the bowel which draws more fluid across the membranes. In other patients the bowel may just be overactive from hormone disorders which causes very frequent bowel motions but the overall volume should remain approximately the same.

Causes of Diarrhoea

By far the most common cause of diarrhoea is infection. Most cases are just mild viral infections caused by rotavirus (which some people may refer to as the stomach flu). This can be easily spread through daycare centres, schools or families. Bacteria such salmonella, campylobacter and shigella are other common causes of diarrhoea.
