Haemorrhoids, Anal Tears and Fissures

What are Haemorrhoids (Piles)?


Haemorrhoids, anal tears and anal fissures can all result in bleeding from the anus, which can be quite alarming. All these conditions are relatively common and in most cases any bleeding is not a cause for alarm. However, any bleeding from the anus should always be investigated immediately as it may be a symptom of a more serious condition.

What Causes Haemorrhoids?

  • Piles are usually caused when you strain to pass a stool. So people who are frequentlyconstipatedand who regularly strain, often suffer from piles.
  • They are also common during orafter pregnancydue to the pressure from the developing baby, hormonal changes and the delivery of the baby.

Smaller piles will disappear naturally when constipation is alleviated.

Larger piles that do not resolve may need treatment from a surgeon.

If there is an irritation or an itch associated with piles, ask your pharmacist for advice. There are a number of preparations that can help ease the discomfort.

How are Haemorrhoids Treated?

注射痔疮是治疗痔疮出血的一种特别有效的方法。It is sometimes calledsclerotherapy. Injecting a small amount of a chemical called phenol into the base of the haemorrhoids causes them to shrink in size. This can take a number of weeks to be effective, so you should not expect immediate results.

Other treatments includebanding,ointments, laser treatment, or surgery.

How to Prevent Haemorrhoids

Unfortunately, having your haemorrhoids injected does not guarantee that they will never come back. Injection usually improves symptoms for a few months, but in many cases the injections need to be repeated. You may also wish to try;

  • Increasing the fibrein your diet is known to be as effective as injections for preventing further problems
  • Increasing your fluidintake which can help prevent further problems with haemorrhoids
  • Avoiding straining and constipation which is the most useful thing patients can do to prevent the problem coming back. If the fibre content of your diet is not sufficient to keep your stools soft, then a fibre supplement can help.

Tears in the Anus & Anal Fissures

Bleeding from the anus can occur if you have passed a rather big and / or hard stool and experienced some pain during and after the passing. This is usually caused by a small tear in the lining of the anal canal.


You can prevent the fissures from reopening by trying to avoid constipation. This will, therefore, make your faeces easy to pass.

Is Bleeding From the Back Passage Serious?

如果肛门出血与肠道疾病有关,而不是肛门本身,那么肛门出血就会很严重。These diseases/conditions include:

  • Cancer of the rectum / lower colon
  • Innocent or benign tumours (polyps)
  • Inflammation of the rectum (proctitis)
  • Inflammation of the colon (colitis)

Your GP will help to evaluate your problem and may use the following procedures when examining you:

  • Examine your abdomen, searching for lumps or tender areas
  • Examine your back passage to check the anal canal

Following these investigations, your GP may decide to send you to a specialist who may investigate further and you may need to undergo some common tests and procedures. To read more about the tests that you may be required to have, please read ourBowel Advice Sheet.
