Constipation is having infrequent bowel movements and bowel movements that are very hard to pass the stool. The one good thing about constipation is that it is not one of those diseases you have but not know about. The first day or two you do not have a bowel movement, you may not notice or pay attention. After that, however, you realize you have an issue. In general, passing stool less than three times a week is classified as constipation.
