In most cases, constipation is treated by instituting some changes in diet (such as eating more fiber), drinking more liquids, or changing medication. Laxatives may be prescribed by a physician when other methods, such as diet and exercise, do not work. Constipation that is more chronic in nature or due to certain problems with the digestive tract may require more intensive treatment such as biofeedback.
