Understanding Haemorrhoids (Piles): Symptoms, Causes, and Relief in the UK

Haemorrhoids, frequently referred to as piles, are swellings containing enlarged blood vessels found inside or around the bottom (the rectum and anus). Many people find the topic embarrassing, but piles are incredibly common in the UK, affecting up to half of the population at some point in their lives. They are not cancerous and are generally not a cause for serious alarm, though they can be uncomfortable and distressing.

There are two main types of haemorrhoids: internal and external. Internal haemorrhoids develop inside the rectum and are usually painless, though they often cause bleeding. External haemorrhoids develop under the skin around the anus and can be more painful, especially when sitting, as they are subject to more nerve sensitivity.

The symptoms of haemorrhoids can vary depending on their location and severity. Common signs to look out for include:

• Bright red blood: You may notice small amounts of bright red blood on the toilet paper or in the toilet bowl after a bowel movement.
• Itchiness and irritation: The skin around the anus may feel itchy (pruritus ani) or sore.
• Lumps: You might feel a soft lump hanging down outside the anus, which may need to be pushed back in after a bowel movement.
• Discomfort or pain: While internal piles are often painless, external or 'prolapsed' piles (those pushed outside the anus) can be quite painful.
• Mucus discharge: A slimy discharge may be noticed after passing a stool.

It is important to remember that while these symptoms often point to piles, they can overlap with other digestive conditions. Always seek professional advice for a first-time occurrence of rectal bleeding.

Haemorrhoids occur when the pressure in the blood vessels in and around the anus increases. This causes the vessels to swell and inflame. Several factors can contribute to this increased pressure:

• Straining during bowel movements: This is the most common cause, often linked to constipation.
• Chronic constipation or diarrhoea: Frequent trips to the toilet or difficulty passing stools puts consistent pressure on the rectal veins.
• Pregnancy: The increased pressure from the growing baby, combined with hormonal changes that relax vein walls, makes piles very common during the third trimester and after childbirth.
• Heavy lifting: Regularly lifting heavy objects can increase abdominal pressure.
• Ageing: The tissues that support the veins in the rectum and anus can weaken and stretch as we get older.
• Diet: A diet low in fibre is a primary contributor to the constipation that triggers piles.

Most mild cases of haemorrhoids will resolve on their own or with simple home treatments within a week or two. The primary goal is to soften the stool and reduce inflammation.

Dietary Adjustments

Increasing your fibre intake is the most effective way to prevent and treat piles. Aim for at least 30g of fibre a day from sources like wholemeal bread, oats, beans, lentils, fruit, and vegetables. Alongside fibre, you must drink plenty of fluids (water is best) to help the fibre work effectively through your system.

Self-Care Practices

Avoid straining when on the toilet and try not to linger, as sitting too long can increase pressure. A 'sitz bath'—soaking the affected area in warm, plain water for 10 to 15 minutes a few times a day—can help soothe irritation. After using the toilet, pat the area gently with damp toilet paper or fragrance-free baby wipes rather than rubbing vigorously.

Over-the-Counter Options

Pharmacists can recommend creams, ointments, or suppositories that contain local anaesthetics or mild steroids to reduce swelling and pain. These should generally not be used for more than 7 days at a time without medical advice.

If home treatments are not effective, a GP or specialist may recommend clinical procedures. In the UK, common non-surgical treatments include:

• Banding: A doctor places a very tight elastic band around the base of the piles to cut off their blood supply. They should then fall off within a week or so.
• Sclerotherapy: A chemical solution is injected into the piles, causing them to shrivel and scar.
• Electrotherapy: A small electric current is used to shrink the haemorrhoids.

In severe or recurring cases, surgical options like a haemorrhoidectomy (removal of the piles) or haemorrhoidal artery ligation may be considered. These are usually performed as day cases in hospital.

While piles are common, they must be differentiated from other more serious conditions. You should book a consultation with an online GP if:

• Your symptoms do not improve after a week of home treatment.
• The pain is significant or preventing you from daily activities.
• You have persistent itching or discharge.
• You are unsure if the symptoms you have are piles.
• You have changed your bowel habits significantly (e.g., going more frequently or having looser stools for more than three weeks).

A GP can provide a diagnosis and prescribe stronger treatments than those available over the counter, or refer you for a physical examination if necessary.
