Constipation

Constipation is the term that refers to difficulty passing bowel movements (also known as stools) although there are a number of commonly used definitions ranging from reduced frequency of bowel movements, to the passage of hard bowel movements that are difficult to pass. There is also a wide range of "normal" bowel movement function in health people and therefore the concept that there is difficulty with bowel movements is important in the definition.

Treatment/Therapy

The treatment usually involves understanding the primary cause and treating this. For instance, if the cause is insufficient fibre in the diet, this should be attended to. A fibre containing or "bulk" laxative may also be useful. Maintaining a good oral fluid intake eg 1.5 liters per day, is also important.
