hello, i also strongly suspect hemorrhoids, but please seek a doctor because hemorrhoids is not the only thing which causes bleeding, it might be some ulcers, or something else.
tc hope he gets well..:)
Could be hemerroids ..you can get meds OTC to help with this or a doctor can prescribe ..
Rectal bleeding is not normal and should always be medically investigated. If the volume of blood is large (I would say 100 ml+) then maybe better to seek urgent medical advice. If the volume of blood is a few drops then not so urgent but still essential to get advice and diagnosis. Google rectal bleeding to find out more - the Medicinenet is particularly informative.
If the diagnosis is inconclusive then maybe request a colonoscopy.
