Piles (haemorrhoids) - Diagnosis 

Diagnosing piles (haemorrhoids) 

Piles (haemorrhoids) are easily diagnosed by your GP. They will examine your anus (the opening at the end of the digestive system where solid waste leaves the body) to check for swollen blood vessels.

It is important to tell your GP:

  • if you have recently lost a lot of weight
  • if your bowel movements have changed
  • what colour your stools are
  • if your stools contain any blood
  • if there is any mucus present in your stools

Digital rectal examination

If your haemorrhoids are internal (see Haemorrhoids - symptoms for an explanation), your GP may perform a digital rectal examination (DRE). Wearing gloves and using lubricant, they will use their finger (‘digit’) to feel for any abnormalities in your anus and rectum (the storage area that holds the stools).

See the Health A-Z topic about Rectal examination for more information on this procedure. 

Proctoscopy

If a closer examination is necessary, your GP may perform a proctoscopy. This is an examination of the inside of your rectum. Your GP may use an instrument called a proctoscope, which is a hollow tube fitted with a light on the end.

A proctoscope makes it possible for your GP to see your entire anal canal (the last section of the bowel). It also allows your GP to take a small tissue sample from inside your rectum, which may be necessary if any laboratory tests need to be carried out.

It is important to see your GP if you experience any bleeding from your anus. You can also call NHS Direct on 0845 46 47 for advice.
