Thrombosed haemorrhoids

A thrombosed haemorrhoid, is the medical term for a haemorrhoid that has become swollen due to a small blood clot within the haemorrhoid. The word ‘thrombosis’ means clotting.

A thrombosed haemorrhoid can occur in both internal and external piles but is more common in external piles. The reason is thought to be down to the extra stress that external haemorrhoids are put under due to where they are located – on the outside of the anus.

Thrombosed haemorrhoid symptoms

Anal itching and spot bleeding are symptomatic of a thrombosed hemorrhoid. As most haemorrhoids are painless, a stronger marker that you have a thrombosed haemorrhoid is the experience of acute pain and swelling in the area around the anus.

Topical treatments will offer relief for the itching symptoms of a thrombosed haemorrhoid, but will not typically result in pain relief as the pain is the result of pressure and swelling within the tissue.

What causes thrombosed haemorrhoids?

It is not fully understood why blood clots form in some external haemorrhoids and not in others. 

You can get haemorrhoids from increased pressure on the veins in your rectum. Causes of this pressure include:

  • straining while you have a bowel movement, especially if you’re constipated
  • diarrhea
  • irregular bowel movements
  • pregnancy, from the force of the baby pressing on your veins or from pushing during delivery
  • sitting for a long period of time, such as during a long car, train, or plane trip
  • Age can be a factor. The blood vessels become weaker, which makes you more susceptible to thrombosed haemorrhoids.

How do I treat a thrombosed hemorrhoid?

There are ways of managing some of the symptoms of a thrombosed haemorrhoid. For example:

  • Over the counter hydrocortisone creams and ointments. If your symptoms need something stronger to manage them, creams with a higher level of steroid are available on prescription from your GP.
  • Sitz baths can bring some relief.
  • Using ice packs around the area whilst sitting in a chair is another technique that’s been known to work.

If the symptoms of thrombosed haemorrhoids become intolerable, then a small surgical procedure that drains the blood clot from the haemorrhoid, called a thrombectomy, can sort the problem out.

This treatment can only be undertaken in the first few days after the haemorrhoid has become thrombosed; otherwise other surgical options may need to be considered.

Depending on the exact nature of your piles the options range from surgical to non-surgical. Electrotherapy is a non-invasive non-surgical treatment that can eradicate your internal piles and for most people, enable you to get back to your life on the same day.

A discreet call to one of our advisors will get you on the first steps to saying goodbye to your piles. Appointments are usually sorted within two weeks. All treatments are carried out by fully qualified registered nurses.

Internal Haemorrhoids

Internal Haemorrhoids

Internal haemorrhoids are actually swollen veins and their support tissues, situated in the lower part of your rectum. Sometimes the blood vessels and associated tissues become weak and stretch so thin that they bulge and become irritated

External Haemorrhoids

External Haemorrhoids

External haemorrhoids are different from internal haemorrhoids in two important ways: the first and most obvious difference is where they are located – external haemorrhoids, as the name suggests, are on the outside of your anus. Internal haemorrhoids are on the inside.

Prolapsed Haemorrhoids

Prolapsed Haemorrhoids

Internal haemorrhoids can “prolapse.” If they prolapse, they become swollen and protrude outside your rectum. They can be quite uncomfortable when this happens and are more likely to be prone to bleeding.


Haemorrhoids stages & grades

If you suffer with haemorrhoids, then understanding how the medical profession grades the different sizes and nature of your piles could be vital in how you approach the treatment of your specific condition.
