Quick answer. Haemorrhoids (piles) are common swollen blood vessels in or around the anus and lower rectum, causing bright-red bleeding on the toilet paper or in the bowl, itching, discomfort or a lump. They often result from straining, chronic constipation or diarrhoea, a low-fibre diet, prolonged sitting on the toilet, pregnancy or ageing, and are first treated with more fibre and fluids, avoiding straining, and topical creams or stool softeners; persistent or severe cases may need rubber band ligation or surgery (haemorrhoidectomy), which is MediSave-claimable as day surgery. Crucially, never assume rectal bleeding is ‘just piles’ – new or persistent bleeding, a change in bowel habit, weight loss or anaemia can signal colorectal cancer and should always be assessed by a doctor, who may recommend a colonoscopy.
Haemorrhoids, commonly called piles, are one of the most frequent reasons Singaporeans see a GP or colorectal surgeon for anal symptoms. They are swollen blood vessels in or around the anus and lower rectum, and while usually benign and treatable, their most common symptom – rectal bleeding – overlaps with that of colorectal cancer, one of the top cancers in Singapore. This guide explains what piles are, why they happen, how they are treated through a step-by-step ladder, and the warning signs that mean you should never self-diagnose bleeding as “just piles.”
At a glance
| Approach | What it involves | Notes |
|---|---|---|
| Lifestyle & conservative | More fibre and fluids, avoiding straining, limiting toilet time, topical creams, sitz baths, stool softeners | First-line for most people; low cost, often manages mild and early piles |
| Rubber band ligation / sclerotherapy | Outpatient office procedures to cut off blood supply or shrink the haemorrhoid | For persistent low-grade (grade 1-3) piles; usually no general anaesthesia |
| Haemorrhoidectomy | Surgical removal of haemorrhoids, done as day surgery | For severe/high-grade (grade 3-4) or recurrent piles; MediSave-claimable |
| Stapled / laser procedures | Repositioning or treating tissue, aiming for less post-op pain | Alternative surgical options; suitability assessed by the surgeon |
| Public hospital (subsidised) day surgery | Total bill benchmark for haemorrhoidectomy (SF836A) | Typical ~$1,016; range ~$669-$1,457 (MOH benchmark) |
| Private hospital day surgery | Total bill benchmark; MediSave/MediShield Life can offset costs | Typical ~$10,200; range ~$8,894-$11,590 |
What are haemorrhoids (piles)?
Haemorrhoids are abnormally swollen blood vessels and supporting tissue in the anus and lower rectum. They are very common and often cause no symptoms at all, only becoming a problem when they enlarge, bleed or prolapse. There are two main types:
- Internal haemorrhoids form inside the anal canal. They are usually painless (the inner lining has few pain nerves) and tend to present with bright-red bleeding or a lump that protrudes during a bowel movement.
- External haemorrhoids form under the skin around the anal opening. They can be felt as lumps and may become painful, especially if a blood clot forms inside them (a thrombosed external haemorrhoid), which can cause sudden, severe pain.
Internal haemorrhoids are graded 1 to 4 by how much they prolapse (slip out of the anus), and this grading guides treatment:
- Grade 1: enlarged but do not prolapse; may bleed but stay inside.
- Grade 2: prolapse on straining but slip back in on their own.
- Grade 3: prolapse and must be pushed back in manually.
- Grade 4: permanently prolapsed and cannot be pushed back in.
What causes piles, and who is at risk?
Piles develop when pressure on the veins around the anus is repeatedly raised, causing them to swell. Common causes and risk factors include:
- Straining during bowel movements, often from chronic constipation or, less commonly, chronic diarrhoea
- A low-fibre diet and insufficient fluid intake, which harden stools
- Prolonged sitting, including long periods on the toilet (for example, reading or using a phone)
- Pregnancy, due to increased pelvic pressure and hormonal changes
- Ageing, which weakens the supporting tissues
- Heavy lifting, obesity and a family history of piles
Many of these factors are modifiable, which is why lifestyle changes are the foundation of treatment and prevention.
Symptoms to watch for
Haemorrhoid symptoms range from mild and self-limiting to bothersome. Typical features include:
- Bright-red bleeding seen on the toilet paper, dripping into the bowl, or coating the stool, usually during or after passing motion
- Itching or irritation around the anus
- Discomfort, soreness or a feeling of incomplete emptying
- A lump or prolapse at the anus that may need to be pushed back in
- Pain, which is more typical of external or thrombosed haemorrhoids
- Mucus discharge around the anus
Mild symptoms often settle within a few days. However, bleeding should never be ignored or assumed to be piles – see the safety section below.
The treatment ladder – from lifestyle to surgery
Treatment generally follows a step-by-step approach, starting with the least invasive options.
1. Conservative and lifestyle measures (first-line for most people):
- Increase dietary fibre (fruit, vegetables, wholegrains) and fluids to soften stools
- Avoid straining and limit time spent sitting on the toilet
- Stool softeners or fibre supplements to ease bowel movements
- Topical creams or suppositories and warm sitz baths to relieve itching and discomfort
2. Office (outpatient) procedures for persistent low-grade (typically grade 1-3) haemorrhoids that do not respond to lifestyle measures:
- Rubber band ligation: a small band is placed around the base of the haemorrhoid, cutting off its blood supply so it shrinks and falls off within days
- Sclerotherapy: a solution is injected to shrink the haemorrhoid
3. Surgery for severe, large, prolapsing (grade 3-4) or recurrent haemorrhoids:
- Haemorrhoidectomy: conventional surgical removal of the haemorrhoids
- Stapled haemorrhoidopexy and newer techniques (such as laser) that reposition or treat tissue with the aim of less post-operative pain
Haemorrhoid surgery in Singapore is typically performed as day surgery and is MediSave-claimable, with MediShield Life or an Integrated Shield Plan potentially offering further coverage. See the table below for indicative cost ranges.
The critical safety message: never assume bleeding is "just piles"
This is the most important point in this guide. Piles are common, but their symptoms overlap with those of colorectal cancer – among the most common cancers in Singapore – and other conditions such as polyps, inflammatory bowel disease or anal fissures. Bright-red rectal bleeding can come from piles or from a tumour, and you cannot reliably tell the difference yourself.
You should see a doctor promptly – and you may need a colonoscopy – if you have any of the following, especially over age 50:
- New or persistent rectal bleeding, or bleeding not clearly linked to passing a hard stool
- A change in bowel habit (new constipation, looser stools, or change in stool calibre) lasting more than a couple of weeks
- Unexplained weight loss, tiredness or symptoms of anaemia
- Dark or mixed-in blood, or a family history of colorectal cancer
Even if you have known piles, do not assume new bleeding is from them. A doctor’s assessment is the only safe way to exclude something serious.
When to see a GP or colorectal surgeon
See a doctor if your symptoms persist beyond about a week, worsen, recur, or interfere with daily life – and without delay if you have any of the red-flag symptoms above. A GP can assess straightforward piles, advise on lifestyle measures and prescribe initial treatment, and will refer you to a colorectal surgeon or gastroenterologist for examination (such as a proctoscopy or colonoscopy) and for procedures or surgery when needed. Singaporeans can access colorectal specialists at public hospitals (for example SGH, NUH and other restructured hospitals) as well as private clinics.
