Hi, I've had an ongoing diahorrea problem for about 4 weeks. I am 64 years of age, in good health and run regularly. I presume that eat a good basic diet of fruit and vegetables and small portions of chicken and fish. I take vitamins and drink plenty of water. I also eat wholemeal bread, cakes and biscuits, I must confess. I never feel like I need to run to the toilet, but I go two or three times a day. I occasionally suffer haemorroid bleeding. I've had 3 colonoscopies-all clear. Does my dietary intake need modifying?
