Hi, I have just today noticed blood in stools, I had a very bad bout of Flu in December 2010 which lasted around 6 weeks, then it went and came back, since then I kept getting colds frequently, I am on a course of immune tablets (Glucasan plus) which is a supplimentary and also take suppliment vitamins I seem to feel fine right now within myself. I do regular exercise and eat healthy and drink plenty, water/cranberry juice and alot of orange juice. I get the normal stress in daily life but nothing too serious, I am physically fit in general with no medical history of anything within the family. would this be anything to do with this. I am a female age 62 yrs. Bediveare.
