I'm a 23 year old male. I've had chronic diarrhea for around 3-4 months now. It just came on out of the blue. The strange thing is, I'm not going to the toilet 5-10 times per day, just 1 or 2 normally, but everytime i do go i have diarrhea. I also get quite embarassing flatulence, which really smells bad. I've been to the doctors and they took a stool sample which came back all clear. They then did a blood test to test for coeliac disease etc but that came back clear also (it showed that I do have a slight drop in iron levels though).

The problem doesn't seem to be linked to any specific food...I have alernately dropped intake of different food groups such as caffeine, milk etc to seek an improvement but no change.

Anyone got any ideas or advice?
