Why Does Constipation Occur

By | June 12, 2023

Constipation occurs when bowel movements become less frequent and stools become difficult to pass. It happens most often due to changes in diet or routine, or due to inadequate intake of fiber. You should call your doctor if you have severe pain, blood in your stools, or constipation that lasts longer than three weeks.

Having fewer than three bowel movements a week is, technically, the definition of constipation. However, how often you “go” varies widely from person to person. Some people have bowel movements several times a day while others have them only one to two times a week. Whatever your bowel movement pattern is, it’s unique and normal for you – as long as you don’t stray too far from your pattern.

Regardless of your bowel pattern, one fact is certain: the longer you go before you “go,” the more difficult it becomes for stool/poop to pass. Other key features that usually define constipation include:

  • Your stools are dry and hard.
  • Your bowel movement is painful and stools are difficult to pass.
  • You have a feeling that you have not fully emptied your bowels.

How common is constipation?

You are not alone if you have constipation. Constipation is one of the most frequent gastrointestinal complaints in the United States. At least 2.5 million people see their doctor each year due to constipation.

People of all ages can have an occasional bout of constipation. There are also certain people and situations that are more likely to lead to becoming more consistently constipated (“chronic constipation”). These include:

Why Does Constipation Occur
  • Older age. Older people tend to be less active, have a slower metabolism and less muscle contraction strength along their digestive tract than when they were younger.
  • Being a woman, especially while you are pregnant and after childbirth. Changes in a woman’s hormones make them more prone to constipation. The baby inside the womb squishes the intestines, slowing down the passage of stool.
  • Not eating enough high-fiber foods. High-fiber foods keep food moving through the digestive system.
