The treatment of constipation in the first and second cases ls based on the treatment of the underlying disorders. The treatment of functional constipation is based on an improvement in life style such as regular consumption of breakfast, proper exercise and dietary therapy, composed of a high-fiber diet, along with drug therapy. Laxatives, such as bulk agents and osmotic agents are used as the first line of treatment because of the low frequency of side effects. Irritant laxatives should not be used for extended periods because of their habit forming characteristics. |
