Diarrhoea

Diarrhoea

In this picture, the causative factors for diarrhoea are shown. Common physiological factors include: Over-stimulation of the parasympathetic system Inhibition of the sympathetic system Presence of bacteria or viruses Over-secretion of water and electrolytes secondary to gastrointestinal irritation These physiological effects can arise from co-morbid disease states and/or concomitant drug use. However, since the most

common aetiologies are self-limiting, drug therapy is rarely indicated. In severe cases or in cases involving paediatric or elderly patients, oral rehydration therapy should be initiated.
