There are many cause of such rectal bleed and bleed can occur from different sites of GIT. the usual causes are anal fissure,hemorrhoids,polyps, colitis/proctitis and cancer.

Before treatment is started cause and site of the bleed has to determined and then only a specific treatment can be proposed.
