What Are Haemorrhoids and When Do You Need Surgery?

Haemorrhoids, commonly known as piles, are swollen blood vessels in and around the lower rectum and anus. They are among the most common conditions seen in surgical practice, affecting around one in three adults at some point in their lives. Despite how common they are, many people suffer in silence for months or years before seeking help.

What Causes Haemorrhoids?

Haemorrhoids develop when increased pressure in the lower rectum causes the blood vessels to swell and enlarge. Common contributing factors include chronic constipation or straining on the toilet, a low-fibre diet, prolonged sitting, pregnancy, and a family history of the condition. They become more common with age as the supporting tissues weaken.

There are two main types. Internal haemorrhoids develop inside the rectum and are graded from I to IV depending on their size and whether they prolapse. External haemorrhoids form under the skin around the anus and can be particularly painful, especially if a blood clot forms within them, a condition called a thrombosed haemorrhoid.

Recognising the Symptoms

The most common symptoms of haemorrhoids include:

  • Bright red bleeding after opening the bowels, typically noticed on the toilet paper or in the pan
  • Itching, irritation or discomfort around the anus
  • A soft lump felt at or around the anal opening
  • A feeling of fullness or incomplete emptying after defaecation
  • Mucus discharge or soiling of underwear
Important: Rectal bleeding should never be assumed to be haemorrhoids without proper assessment, particularly in adults over 40. A specialist can examine you and confirm the diagnosis, excluding other causes including polyps or colorectal cancer.

When Can Haemorrhoids Be Managed at Home?

Mild haemorrhoids often respond well to simple lifestyle measures. Increasing dietary fibre, through fruit, vegetables and wholegrains, softens the stool and reduces straining. Drinking plenty of water, avoiding prolonged sitting on the toilet, and using topical creams for short-term symptom relief can all help. Most grade I and II internal haemorrhoids improve with these measures alone.

When Do You Need a Specialist?

You should seek specialist assessment if your symptoms are not improving with lifestyle changes, if bleeding is persistent or heavy, if a prolapsed haemorrhoid cannot be pushed back in, or if you are experiencing significant pain. A specialist can confirm the diagnosis and offer a range of treatment options tailored to the severity of your symptoms.

Treatment Options

Banding (Rubber Band Ligation)

The most commonly used outpatient procedure for internal haemorrhoids. A small rubber band is placed around the base of the haemorrhoid, cutting off its blood supply. The haemorrhoid shrinks and falls off within a few days. The procedure takes only a few minutes and requires no anaesthetic.

Haemorrhoidectomy

Surgical removal of the haemorrhoids under general or spinal anaesthetic. This is the most definitive treatment for grade III and IV haemorrhoids or those that have not responded to banding. Modern techniques including LigaSure haemorrhoidectomy and the HALO (Haemorrhoidal Artery Ligation) procedure offer effective alternatives with less post-operative pain.

Transanal Haemorrhoidal Dearterialisation (THD)

A minimally invasive procedure in which the blood supply to the haemorrhoids is reduced using Doppler-guided ligation, without removing tissue. Associated with less pain and a faster return to normal activities compared to conventional haemorrhoidectomy.

What to Expect After Treatment

Most haemorrhoid procedures are performed as day cases. You go home the same day. Recovery depends on the procedure: banding requires virtually no recovery time, while surgical haemorrhoidectomy typically involves one to two weeks of reduced activity. Maintaining a high-fibre diet and good toilet habits after treatment is essential to prevent recurrence.

If you are troubled by haemorrhoid symptoms, an early specialist assessment can confirm your diagnosis and identify the most appropriate treatment. Most patients are pleasantly surprised by how straightforward and effective modern treatments are.
