Bleeding from the bottom (rectal bleeding)Overview

A small amount of one-off bleeding from the bottom isn't usually a serious problem. But a GP can check.

Check if you're bleeding from the bottom

You might be bleeding from the bottom if you have:

  • blood on your toilet paper
  • red streaks on the outside of your poo
  • pink water in the toilet bowl
  • blood in your poo or bloody diarrhoea
  • very dark, smelly poo (this can be blood mixed in poo)

A small amount of one-off bleeding can often go away on its own without needing treatment.

See a GP if:

  • your child has blood in their poo
  • you've had blood in your poo for 3 weeks
  • your poo has been softer, thinner or longer than normal for 3 weeks
  • you're in a lot of pain around the bottom
  • you have a pain or lump in your tummy
  • you've been more tired than usual
  • you've lost weight for no reason

Get an urgent appointment or call 111 if:

  • your poo is black or dark red
  • you have bloody diarrhoea for no obvious reason

Go to A&E or call 999 if:

  • you're bleeding non-stop
  • there's a lot of blood – for example, the toilet water turns red or you see large blood clots
