Certain chemotherapies and radiotherapy of the abdominal region can lead to diarrhoea. The reason for this is often inflamed intestinal mucosa.
Diarrhoea appears as frequent liquid or watery stools (usually more than three times a day). Diarrhoea is sometimes also accompanied by abdominal pain or abdominal cramps. The quantity of stool perceived as normal is increased. Left untreated, prolonged diarrhoea can lead to serious health problems.
However, diarrhoea can often be controlled with simple remedies, and drugs are available for its treatment.
