What is constipation?

alt

It’s a common digestive problem; it may be hard for you to have a bowel movement or your bowel movement may not be regular. 3
Your stools may be very hard, making them so difficult to pass that you have to strain. Or you may feel an uncomfortable fullness even after you have had a bowel movement. 3
