Constipation (C0009806)

Definition (CCC) Impression of infrequent or difficult passage of hard, dry feces without cause
Definition (CCC) Difficult passage of hard, dry, feces
Definition (MEDLINEPLUS)

Constipation means that a person has three or fewer bowel movements in a week. The stool can be hard and dry. Sometimes it is painful to pass. At one time or another, almost everyone gets constipated. In most cases, it lasts a short time and is not serious.

There are many things you can do to prevent constipation. They include

  • Eating more fruits, vegetables and grains, which are high in fiber
  • Drinking plenty of water and other liquids
  • Getting enough exercise
  • Taking time to have a bowel movement when you need to
  • Using laxatives only if your doctor says you should
  • Asking your doctor if medicines you take may cause constipation

It's not important that you have a bowel movement every day. If your bowel habits change, however, check with your doctor.
