A doctor can perform a series of tests to see if a problem like this is the cause of constipation. If so, the problem can often be treated. If you become constipated, first see the doctor to rule out a more serious problem. Dried fruit such as apricots, prunes, and figs are especially high in fiber. But be aware that some people become constipated from drinking large amounts of milk.
Some people suffer from bloating and gas for several weeks after adding bran to their diets.
Make diet changes slowly, to allow the digestive system to adapt. Remember, if your diet is well balanced and contains a variety of foods high in natural fiber, it may not be necessary to add bran to other foods. Do not expect to have a bowel movement every day or even every other day. Regularity differs from person to person. We welcome your questions and comments.
