Experiencing constipation

When I talked to my father today,he told me that it's been a while that he experience constipation on and off.He just don't mind it,thinking his bowel movement will be better.But these days,it really bothers him.I told him to take best colon cleanse or eat many fruits and vegetables since it has a lot of fibers for him to have a good bowel movement.

I know some people who have colon cancer and I am really afraid for my father since he is over fifty now.Here in my place,men who are in their fifties have to undergo some check ups to know if they have problems in their colons.I just hope my father will not have it.
