A small amount of one-off bleeding from the bottom is not usually a serious problem. But a GP can check.
Signs of 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 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
Go to A&E or call 112 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
Do not drive to A&E. Ask someone to drive you or call 112 and ask for an ambulance.
Bring any medicines you take with you.

If you have bleeding from your bottom, a GP will check what's causing it.
They might:
- check your bottom (rectum) with a gloved finger (rectal examination)
- ask for a sample of poo for testing
