I have had colon issues in the past fissures, polyps and hemorrhoids. I had my gallbladder removed a year ago and now I am experiencing constipation. I eat a diet high in fiber and protein. I drink around 3 liters of water a day. Also because of my work I am very active. I would like to know if there maybe a problem with the bile secretion. My fat intake is extremely low. I am on nexiam 20mg twice a day.

Any advice would be highly appreciated.
