How many time should a healthy adult, who drinks a lot of water go to the toilet. when do you know for sure its constipation and you need medication?

Hard difficult BM: Constipation is a hard, difficult, painful bowel movement. Drinking a lot of water helps but so would more fiber in your diet. The frequency of the bowel movement is not as important as the consistency and pain associated with the bowel movement. A easily passed bm every three days would not be considered constipation by most mds.
