Diagnosing Haemorrhoids

Your GP can diagnose haemorrhoids (piles) by examining your back passage to check for swollen blood vessels.

Some people with haemorrhoids are reluctant to see their GP. However, there’s no need to be embarrassed – all GPs are used to diagnosing and treating piles.Diagnosing haemorrhoids

It’s important to tell your GP about all of your symptoms – for example, tell them if you’ve recently lost a lot of weight, if your bowel movements have changed, or if your stools have become dark or sticky.

Rectal Examination

Your GP may examine the outside of your anus to see if you have visible haemorrhoids, and they may also carry out an internal examination called a digital rectal examination (DRE).

During a DRE, your GP will wear gloves and use lubricant. Using their finger, they’ll feel for any abnormalities in your back passage. A DRE shouldn’t be painful, but you may feel some slight discomfort.


In some cases, further internal examination using a proctoscope may be needed. A proctoscope is a thin hollow tube with a light on the end that’s inserted into your anus.

This allows your doctor to see your entire anal canal (the last section of the large intestine).

GPs are sometimes able to carry out a proctoscopy. However, not all GPs have the correct training or access to the right equipment, so you may need to go to a hospital clinic to have the procedure.

Types of Haemorrhoids

After you’ve had a rectal examination or proctoscopy, your doctor will be able to determine what type of haemorrhoids you have.

Haemorrhoids can develop internally or externally. Internal haemorrhoids develop in the upper two-thirds of your anal canal and external haemorrhoids in the lower third (closest to your anus). The nerves in the lower part can transmit pain messages, while the nerves in the upper part can’t.

Haemorrhoids can be further classified, depending on their size and severity. They can be:

  • First degree – small swellings that develop on the inside lining of the anus and aren’t visible from outside the anus
  • Second degree –larger swellings that may come out of your anus when you go to the toilet, before disappearing inside again
  • Third degree – one or more small soft lumps that hang down from the anus and can be pushed back inside (prolapsing and reducible)
  • Fourth degree –larger lumps that hang down from the anus and can’t be pushed back inside (irreducible)

It’s useful for doctors to know what type and size of haemorrhoid you have, as they can then decide on the best treatment.
