Watery stools are called diarrhea. Constipation is a condition in which too much water has been
absorbed and the stool becomes hard and difficult to pass. Any condition, such as irritation of the colon by bacteria that rushes food residue through the large intestine before that organ has had sufficient time to absorb the remaining water, is known as diarrhea. Constipation may ensue from the lack of fiber in the diet, improper bowel habits, laxative abuse, or anything that decreases motility.
