This has happened a few times now. In the past I've found blood in my poop and seen the doctor because of it and was told there was nothing to worrie about.

Recently I was cleaning my lower region when I noticed a kind of light, clear red blood appear on the toilet paper and none in the poop? There was no pain at all and this has happened twice within a month.

I'm 22. I usually have a drink or 2 in the evning after work and I think this seems to happen after I've had a few as I noticed this on a Saterday after I had drunk about 3 cans and 1 pint. I had eaten quite a lot at the time if that helps?

Could this be liver, kidney damage, something worse or nothing at all??
