What is constipation?
Constipation can mean that your stools are hard and dry or that you have difficulty passing a bowel movement. In medical terms, constipation is generally considered to be fewer than three bowel movements per week.
Also, constipation is not just about not going, but also the quality of the stool. Hard, dry stools are difficult to pass. Normal stools are soft and formed, and are passed without straining.
