Other symptoms of constipation include hard stools that are difficult to pass, or a sensation of incomplete evacuation.

The list of medications that can be culprits includes antidepressants, antacids containing aluminum or calcium, iron supplements, anticonvulsants for epilepsy, pain medications (especially narcotics), tranquilizers, diuretics, calcium channel blockers for hypertension and heart conditions, and drugs to treat Parkinson's disease.

If you don't eat many fruits, vegetables, or whole grains, constipation can occur. High-fat meats, dairy products, eggs, and rich desserts also can cause constipation. To help avoid constipation, eat more fresh fruits and vegetables, either cooked or raw, and more whole-grain cereals and breads. Dried fruits such as apricots, prunes, and figs are especially high in fiber.

If your teeth are in poor shape, you may choose soft, processed foods to eat. Those foods contain minimal fiber.

Older adults sometimes don't drink enough fluids, especially if they are not eating regular meals. Water and other liquids add bulk to stools, making bowel movements easier. The National Institute of Diabetes and Digestive and Kidney Diseases recommends drinking enough fluid every day to prevent dehydration. Check with your doctor on the amount that's appropriate for you, especially if you have heart, blood vessel, or kidney problems. Be aware that some people become constipated from drinking large amounts of milk.

Laxatives are safe to use for constipation. It is not true that they are habit forming. But if you need to use laxatives often, talk with your healthcare provider about other ways to treat constipation. He or she will probably have you drink more water, get more exercise, and add fiber to your diet. You may take over-the-counter laxatives sometimes, Adding fiber to your diet or a fiber supplement may solve the problem. Some people take mineral oil safely in small amounts. But don't take mineral oil if you have problems swallowing. It can be dangerous if the oil goes into your lungs (aspirated). Talk with your provider if you have other symptoms with your constipation, such as abdominal pain or black or bloody stools. Also talk with your provider if your symptoms don't go away even after adding fiber and drinking more water.

Keep in mind that regularity differs from person to person. If your bowel movements are usually painless and occur regularly (whether 2 times a day or 3 times a week), then you are probably not constipated.
