What is Constipation?
Being constipated means your bowel movements are difficult or happen less often than normal. Almost everyone has it at some point in life, and it‘s usually not serious. Still, you‘ll feel much better when your system is back on track.
The normal length of time between bowel movements varies widely from person to person. Some people have bowel movements three times a day. Others have them only once or twice a week.
Going longer than three or more days without one is usually too long. After three days, the stool or feces become harder and tougher to pass.
