Top Definition
A bowel motion (or bowel action) is what results when a person defecates (see defecation), or passes solid or semi-solid material ('poo') from the anus.

Most people have one bowel motion ('poo') each day, but the usual range in the population varies from three or four bowel motions a day to one a week.

The type of bowel motions produced can be an indication of the health of the person passing them. For example, people who are constipated produce hard turds because their digestive system is sluggish and a great deal of water is absorbed in the large intestine from the 'poo'. On the other hand, people with diahorrea have watery bowel motions. If you notice blood in your bowel motions, you should see a doctor.

Lara went to the doctor because she was constipated and hadn't had a bowel motion (or 'poo') for ten days. She normally went to the toilet to 'poo' once a day. The doctor gave her a laxative, and she had a bowel motion the next day.
