Distinguish between constipation and indigestion. Mention their major causes.
Constipation, the faeces are retained within the rectum and the bowel movement occurs regularly.
Indigestion, the food which consumed will not get digested properly leading to a feeling of fullness.
The causes of constipation are the fewer intakes of water and roughage in the diet whereas indigestion is caused by the inadequate enzyme secretion, anxiety and food poisoning.
