What do it mean to bleed in reactum badly?

Multiple causes: 2 of the simpler causes are diverticulosis/itis (pouches in the colon that get inflamed by seeds/nuts/popcorn & bleed) and hemorrhoids (swollen rectal veins that may bleed or clot & be very painful). A tear in the ring muscle of the anus (fissure) can also bleed heavily. Then we come to tumors: anal or rectal tumors or colon tumors (benign polyps or cancers) see doctor for thorough exam ± colonosc.

See the doctor: There can be many reasons for rectal bleeding, but all of them should be evaluated by a doctor! see a colorectal surgeon who will do a complete examination.
