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.
