DiarrheaDiarrhoea is the body's attempt to expel an irritant from the bowel. Infection and food poisoning cause inflammation in the gastrointestinal tract, resulting in diarrhoea and vomiting.
A number of antibiotics can upset the balance of the natural flora of the gut giving rise to diarrhoea. It may also be a symptom of colitis, Crohn's Disease and IBS.
Stress may be a significant factor causing over stimulation of the bowel, while chronic diarrhoea may be a sign of food allergy, often related to dairy products or wheat.
Tannins exert an 'astringent' action on the bowel. This helps to relieve inflammatory bowel conditions and reduce the frequency and severity of loose motions.
