My mum is bleeding from from the anal what does that mean?

BRBPR: This may just be hemorrhoids from straining but bleeding from rectum (brbpr) may also indicate anal fissures, proctitis (due to infection, inflammatory bowel disease, radiation therapy, stercoral ulcers, rectal prolapse, trauma, etc.) or a bleeding source further upstream. Depending on age, risk factors, current medication (aspirin, nsaid's, anticoagulants cause bleeding), get her evaluated asap.
