I have the worst constipation always though it has gotten better since I am healthy. In the hospital they gave us tennis balls to roll on our stomach to stimulate. It never worked for me and the yucky enema was needed. For me consistent water,high fiber but not too much fiber,and as much activity my painful body can get. Some people have good luck with fiber one cereal bt if you don't drink enough watch out. On Oprah yesterday dr oz was saying you should take calcium with magnesium to not get blocked. I take both but seperate pills.
