Hemorrhoids / Piles

Introduction

Hemorrhoids, commonly called piles, are one of the most familiar conditions in general surgery clinics. They are swollen blood vessels in and around the anus and lower rectum. Almost everyone has hemorrhoidal tissue as a normal part of their anatomy — it is only when these cushions of tissue become enlarged, irritated, or displaced that they cause symptoms such as bleeding, itching, discomfort, or a visible lump.

If you are reading this, you have probably already noticed some of these symptoms, spoken to a doctor, or been told you have piles. The good news is that hemorrhoids are very treatable. Most cases settle with simple changes to diet, bowel habits, and over-the-counter treatments. When symptoms persist or the hemorrhoids are more advanced, a range of office-based procedures and surgical options exists. This article explains what hemorrhoids are, why they form, how they are graded, and how doctors approach treatment at each stage.

What Are Hemorrhoids?

The anus — the opening at the end of the digestive tract — is lined with small bundles of blood vessels, smooth muscle, and connective tissue. These bundles act as cushions that help with continence (keeping stool in place between bowel movements). When the veins inside these cushions become enlarged or the supporting tissue weakens, the cushions slip down or bulge outward. This is what doctors call a hemorrhoid.

Hemorrhoids are extremely common. Studies suggest that around half of all adults will experience symptoms at some point, especially between the ages of 45 and 65. They affect men and women roughly equally and are particularly common during and after pregnancy.

Internal versus external hemorrhoids

• Internal hemorrhoids develop above the dentate line. The tissue here has few pain-sensing nerves, so internal hemorrhoids are often painless. The most common symptom is bright red bleeding during or after a bowel movement. In more advanced cases, the tissue may slip out through the anus (this is called prolapse).
• External hemorrhoids develop below the dentate line, under skin that does have pain-sensing nerves. They can feel like a soft lump near the anal opening and may cause itching, irritation, or pain — particularly if a blood clot forms inside (a thrombosed external hemorrhoid).
• Mixed hemorrhoids involve both internal and external components in the same area.

Grading of internal hemorrhoids

• Grade I: The hemorrhoid bulges into the anal canal but does not come out through the anus. Bleeding is the usual symptom.
• Grade II: The hemorrhoid prolapses (comes out) during a bowel movement but returns inside on its own afterwards.
• Grade III: The hemorrhoid prolapses during a bowel movement and must be pushed back in by hand.
• Grade IV: The hemorrhoid is prolapsed all the time and cannot be pushed back in. This stage is also where most thrombosed or strangulated cases sit.

External hemorrhoids are not graded the same way. They are usually described by their symptoms — for example, an “acutely thrombosed external hemorrhoid” refers to one in which a painful blood clot has formed.

Causes and Risk Factors

Hemorrhoids form when pressure inside the veins of the anal canal rises and the supporting tissues weaken over time. Several factors contribute to this.

Common causes and contributing factors

• Chronic constipation and straining: Pushing hard during bowel movements is one of the strongest contributing factors. Repeated straining stretches and weakens the anal cushions.
• Chronic diarrhoea: Frequent loose stools and repeated wiping also irritate the area and raise pressure.
• Low-fibre diet and inadequate fluid intake: These lead to harder stools that are more difficult to pass.
• Prolonged sitting on the toilet: Spending long periods on the toilet (including reading or scrolling on a phone) puts continuous downward pressure on the anal veins.
• Pregnancy and childbirth: The growing uterus increases pelvic pressure, and the act of pushing during vaginal delivery can cause hemorrhoids to appear or worsen.
• Heavy lifting and certain occupations: Jobs that involve repeated heavy lifting or long hours of standing or sitting can be a factor.
• Aging: The connective tissue that holds the anal cushions in place weakens with age.
• Obesity: Higher abdominal pressure adds to vein pressure in the pelvis.
• Family history: A tendency for piles can run in families, possibly related to inherited connective tissue strength.

Some conditions, such as chronic liver disease or pelvic tumours, can raise pressure in the veins draining the rectum and contribute to hemorrhoids, although these are less common causes.

Signs and Symptoms

Even after a diagnosis, it helps to know which symptoms are typical and which suggest a need to go back to your doctor. Common symptoms include:

• Bleeding: Bright red blood on toilet paper, dripping into the toilet bowl, or coating the outside of the stool. The blood is usually painless and appears at the end of a bowel movement.
• A lump or swelling around the anus: This may be soft and easy to push back, or firm and tender if a clot has formed.
• Itching or irritation around the anal area.
• Discomfort, soreness, or aching, especially after sitting for long periods or after passing stool.
• Mucus discharge, which can cause skin irritation.
• A feeling of incomplete emptying after a bowel movement.

It is important to know what hemorrhoid bleeding does not typically look like. Dark, tarry stools; blood mixed throughout the stool; significant blood loss; weight loss; or a change in bowel habits over weeks or months are not typical of hemorrhoids and need separate medical evaluation. These features can point to other conditions, including bowel cancer, that require investigation. Even when piles are present, doctors will often want to rule out other causes of bleeding, especially in people over 40 or those with risk factors for bowel cancer.

Diagnosis

Hemorrhoids are diagnosed by a combination of your history and a clinical examination. Many patients feel anxious about this examination, but it is brief and routine for the doctor.

What the examination involves

• External inspection: The doctor will look at the area around the anus for external hemorrhoids, skin tags, fissures (small tears), or other abnormalities.
• Digital rectal examination: The doctor gently inserts a gloved, lubricated finger into the anus to feel for masses, tenderness, or other findings. Internal hemorrhoids themselves are often too soft to feel this way, but the examination helps rule out other conditions.
• Anoscopy or proctoscopy: A short, lighted tube is gently inserted into the anal canal to allow the doctor to see internal hemorrhoids directly and assess their grade. This is the main test used to confirm and grade internal hemorrhoids.

When further tests are needed

If there is any concern about the cause of bleeding — for example, in older patients, those with a family history of bowel cancer, those with significant or atypical bleeding, or those with changes in bowel habit — the doctor may recommend a colonoscopy or flexible sigmoidoscopy. These tests use a longer flexible camera to examine the lower or entire large bowel for other sources of bleeding. Major societies emphasise that hemorrhoids should not be assumed to be the only cause of rectal bleeding without considering whether other investigations are needed.

Treatment and Management

Treatment depends on the type of hemorrhoid, its grade, the severity of symptoms, and the patient’s overall health. Current guidance from the American Society of Colon and Rectal Surgeons (ASCRS) and other major bodies favours a stepped approach: start with conservative measures, move to office-based procedures if those are not enough, and consider surgery for advanced disease or when other treatments have not worked.

Conservative (non-surgical) treatment

For grade I and many grade II internal hemorrhoids, and for most external hemorrhoids without thrombosis, conservative measures are the foundation of care. Doctors commonly recommend:

• Increased dietary fibre: Fibre softens stool and reduces straining. Major guidelines recommend a gradual increase to around 25–35 grams of fibre per day from whole grains, fruits, vegetables, legumes, and seeds.
• Adequate fluid intake: Drinking enough water helps fibre work properly.
• Fibre supplements: Bulk-forming agents such as psyllium (ispaghula) or methylcellulose are often added when dietary fibre alone is not enough. Clinical studies have shown these reduce bleeding and discomfort over several weeks of use.
• Bowel habit changes: Avoiding prolonged sitting on the toilet, not straining, and going when the urge first appears.
• Sitz baths: Sitting in warm water for 10–15 minutes a few times a day, particularly after bowel movements, can ease discomfort and itching.
• Topical creams and ointments: A range of over-the-counter and prescription preparations is available, including soothing creams, mild local anaesthetic ointments, and short courses of low-potency topical steroids. These can relieve symptoms but are usually used for limited periods (often no more than a week) to avoid skin thinning.
• Flavonoid medications: Oral preparations such as micronised purified flavonoid fractions (containing diosmin and hesperidin) are commonly prescribed in many countries, including India, and have evidence for reducing bleeding and symptoms in acute flare-ups.
• Pain relief: Simple painkillers such as paracetamol can help. Some doctors advise caution with anti-inflammatory drugs (like ibuprofen) if there is active bleeding, and codeine-based painkillers should generally be avoided because they cause constipation.

Whether all of these are appropriate in a given person is a clinical decision based on the type, grade, and symptoms.

Treatment of thrombosed external hemorrhoids

A thrombosed external hemorrhoid — one with a sudden, painful clot — is a particular situation. If it is seen within the first 48 to 72 hours of symptom onset and the pain is severe, doctors may offer a minor procedure to remove the clot under local anaesthetic, which gives rapid relief. After 72 hours, the body usually begins to reabsorb the clot on its own, and conservative measures (sitz baths, pain relief, stool softeners) are typically preferred. A small skin tag may remain afterwards.

Office-based procedures

If symptoms persist despite conservative measures, or for grade II and many grade III internal hemorrhoids, doctors often recommend an office-based procedure. These are usually done in the clinic or day-care setting, without a general anaesthetic, and have shorter recovery than surgery.

Rubber band ligation is the most widely used office procedure for internal hemorrhoids, particularly grade II and III. A small rubber band is placed around the base of the hemorrhoid through an anoscope. The band cuts off the blood supply, and the hemorrhoid shrinks and falls off over a few days, leaving a small scar that helps anchor the tissue. Most patients experience a feeling of fullness or mild discomfort for a day or two. Bleeding can occur when the banded tissue separates, usually within the first week or two. Major societies describe rubber band ligation as the most effective of the office procedures for early internal hemorrhoids.

Sclerotherapy involves injecting a small amount of a chemical solution into the base of the hemorrhoid, causing the blood vessels to shrink and the tissue to scar down. It is often used for grade I and small grade II hemorrhoids and can be useful for patients on blood thinners, where banding carries a higher bleeding risk.

Infrared coagulation uses pulses of infrared light directed at the base of the hemorrhoid to cause the tissue to shrink. It is most effective for grade I and II hemorrhoids and is generally well tolerated.

Other less commonly used office techniques include bipolar diathermy and cryotherapy. Each of these procedures has slightly different evidence behind it, and the choice often depends on what the local clinic offers and on the doctor’s experience.

Recurrence can happen after any office procedure, and a course of treatment may need to be repeated. None of these are guaranteed permanent fixes, but they avoid the longer recovery of surgery.

Surgical treatment

Surgery is generally reserved for grade III hemorrhoids that have not responded to other treatments, for grade IV hemorrhoids, for large mixed hemorrhoids with significant external components, for thrombosed or strangulated hemorrhoids in some situations, and when other treatments have failed. Several techniques are in use.

Conventional hemorrhoidectomy — also called excisional hemorrhoidectomy — involves surgically removing the enlarged hemorrhoidal tissue. The two main variations are the open (Milligan–Morgan) technique, where the wound is left open to heal, and the closed (Ferguson) technique, where the wound is stitched closed. Both can be done with scalpel, electrocautery, or modern energy devices such as the LigaSure or harmonic scalpel, which some studies suggest reduce postoperative pain. Hemorrhoidectomy has the lowest recurrence rate of all the treatments but is also the most uncomfortable in the first one to two weeks of recovery. Major societies describe it as the most effective option for advanced (grade III and IV) and large mixed hemorrhoids.

Stapled hemorrhoidopexy (also known as the PPH procedure, or stapled anopexy) does not remove the hemorrhoid tissue. Instead, a circular stapling device is used to remove a ring of tissue above the hemorrhoids, lifting (or “pexing”) them back to their normal position and interrupting their blood supply. Recovery is typically less painful than conventional surgery and patients often return to normal activities sooner. However, long-term studies show a higher recurrence rate than conventional hemorrhoidectomy, and there are specific complications associated with the technique, so the choice is individual.

Doppler-guided hemorrhoidal artery ligation (HAL or THD) uses a small ultrasound probe to identify the arteries supplying the hemorrhoids. The surgeon then ties off these arteries with stitches, reducing blood flow and causing the hemorrhoids to shrink. The technique is often combined with a procedure called mucopexy, in which the prolapsing tissue is stitched back into position. Pain after this procedure is generally less than after conventional hemorrhoidectomy. Like stapled hemorrhoidopexy, recurrence rates may be higher than with excisional surgery, particularly for very large hemorrhoids.

The choice between these surgical approaches depends on the grade and type of hemorrhoids, the surgeon’s experience, the equipment available, and patient preference after a discussion of trade-offs between pain, recovery time, and recurrence.

Recovery After Hemorrhoid Treatment

Recovery varies widely depending on which treatment has been used. Knowing what is normal helps you plan and recognise problems early.

After conservative treatment

Symptoms from a flare-up usually improve within days to weeks with fibre, fluids, and other simple measures. Habits such as adequate fibre intake and avoiding straining are intended to be long-term, not short courses.

After office-based procedures

Most patients return to normal activity within one to two days after rubber band ligation, sclerotherapy, or infrared coagulation. A feeling of pressure or fullness in the lower rectum is common for the first 24 to 48 hours after banding. Light bleeding can occur up to 7–14 days afterwards, when the banded tissue separates. Doctors usually advise avoiding straining, heavy lifting, and very firm stools during this period.

After surgery

Recovery after conventional hemorrhoidectomy is the longest of all hemorrhoid treatments. The first one to two weeks are often the most uncomfortable, particularly during bowel movements. Most patients need:

• Pain relief as prescribed, usually a combination of paracetamol and another agent, plus topical preparations.
• Stool softeners or laxatives for the first few weeks to keep stools soft.
• Sitz baths several times a day, especially after bowel movements.
• Time off work, typically 1–3 weeks for desk-based work and longer for physically demanding jobs.

Most people are back to normal activity within 2–4 weeks, although mild discomfort and occasional small amounts of bleeding can continue for longer. Stapled and Doppler-guided procedures generally have shorter recoveries, often a week or less of significant discomfort. Your surgeon will give you specific guidance about wound care, when you can drive, and when you can return to exercise.

Constipation in the early days after surgery is a common problem because of pain medications and fear of pain on passing stool. This can lead to a hard stool that is then very painful to pass, so keeping the stool soft from day one is important.

Risks and Complications

All treatments carry some risks, although serious complications are uncommon with hemorrhoid care.

Office procedures

• Bleeding, typically minor; rarely heavy enough to need re-treatment.
• Pain or vasovagal symptoms at the time of the procedure.
• Urinary retention, particularly after banding.
• Infection, rare but reported — including, very rarely, pelvic infections after banding. Severe or worsening pain, fever, or difficulty passing urine after a banding procedure should prompt urgent medical review.
• Recurrence, meaning the need for further treatment.

Surgery

• Pain, often significant in the first week or two after conventional hemorrhoidectomy.
• Bleeding, early (in the first 24 hours) or delayed (around 7–14 days).
• Urinary retention, requiring temporary catheter use in some patients.
• Infection of the surgical area.
• Anal stenosis — narrowing of the anal canal from scarring — uncommon, but can cause difficulty passing stool.
• Incontinence — usually minor and temporary, but persistent in a small number of patients.
• Recurrence, lower than with office procedures but still possible.
• Specific complications of stapled hemorrhoidopexy, such as a feeling of urgency, staple-line problems, or rare but serious complications including rectal injury. These are part of the discussion when choosing between techniques.

Patients on blood-thinning medications, with bleeding disorders, with significant heart or lung disease, or with immune suppression need extra planning before any procedure. These factors are part of the routine pre-procedure discussion.

Lifestyle and Self-Management

Because hemorrhoids tend to recur if the original triggers continue, long-term self-management is a major part of treatment. The same measures that help in the acute phase form the basis of ongoing care.

Diet

• Aim for the fibre intake recommended by your doctor or dietitian, often around 25–35 grams per day. Common high-fibre foods include whole grains, oats, beans, lentils, vegetables, fruit (with skin where edible), and seeds.
• Increase fibre gradually to avoid bloating and gas.
• Drink enough water and other non-caffeinated fluids to keep stools soft.
• Limit very spicy foods and excessive alcohol if you notice these worsen symptoms; the link is not the same for everyone.

Bowel habits

• Go when you feel the urge; delaying makes stool harder.
• Avoid straining. If a bowel movement does not happen within a few minutes, get up and try again later.
• Keep toilet time short. Reading, working, or using a phone on the toilet contributes to prolonged sitting and pressure.
• Some people find that a small footstool, which raises the knees above the hips, helps them pass stool more easily.

Activity and weight

• Regular physical activity helps bowel function and reduces constipation.
• Avoid heavy lifting where possible, and use proper technique (engaging the legs and core, not holding the breath) when lifting is unavoidable.
• Reaching and maintaining a healthy weight reduces pressure on the pelvic veins.

Anal hygiene

• Gentle cleansing with water is usually best. Many doctors advise using moist wipes or rinsing rather than dry toilet paper.
• Avoid heavily scented soaps, perfumed wipes, or vigorous wiping, which can irritate the skin.
• Pat the area dry rather than rubbing.

Hemorrhoids in Pregnancy

For most pregnant and post-partum women, hemorrhoids improve significantly within a few weeks of delivery. Treatment during pregnancy and breastfeeding is generally conservative: fibre, fluids, sitz baths, and selected topical preparations considered safe in pregnancy. Some oral and topical medications used for piles are not recommended during pregnancy, so any treatment should be guided by your obstetrician or family doctor. Office procedures and surgery are usually deferred until after delivery, unless symptoms are severe.

When to Seek Urgent Care

Most hemorrhoid symptoms are not emergencies. However, you should contact a doctor promptly or seek urgent care if you experience:

• Heavy bleeding, large clots, or bleeding that does not stop
• Light-headedness, dizziness, fainting, or rapid heart rate (possible signs of significant blood loss)
• Severe, increasing pain, especially with fever or feeling unwell after a procedure
• Inability to pass urine after a procedure
• A persistent change in bowel habit, unintentional weight loss, or stools that are black or contain dark blood — these need separate evaluation regardless of whether piles are also present

Frequently Asked Questions

Are hemorrhoids and piles the same thing?

Yes. “Piles” is the everyday term and “hemorrhoids” is the medical term. They refer to the same condition.

Will my hemorrhoids go away on their own?

Mild hemorrhoids, particularly those from a short period of constipation or pregnancy, often settle on their own with simple measures. More established hemorrhoids tend to come and go; they may improve with treatment but recur if the underlying triggers (such as straining or a low-fibre diet) continue.

Are hemorrhoids dangerous?

Hemorrhoids themselves are not dangerous in most cases. The main concerns are persistent symptoms, repeated bleeding (which can occasionally lead to anaemia), and the small risk that other, more serious causes of bleeding could be mistaken for piles. That is why doctors take a careful history and may suggest further tests in selected patients.

Can hemorrhoids turn into cancer?

No, hemorrhoids do not turn into cancer. However, the symptoms of hemorrhoids (especially bleeding) can overlap with the symptoms of bowel cancer. This is why bleeding should always be assessed by a doctor rather than assumed to be piles.

Is surgery always needed for advanced piles?

Not always. Even grade III hemorrhoids can sometimes be controlled with banding or other office procedures, particularly if they are not very large. Grade IV and severely symptomatic mixed hemorrhoids are more likely to need surgery. The right path is a decision between you and your surgeon based on your symptoms, your overall health, and the available techniques.

How long will I need off work after hemorrhoid surgery?

For conventional hemorrhoidectomy, most people with desk-based jobs return to work within 1–3 weeks. Physically demanding work usually requires longer. Office procedures often require only a day or two of rest. Your surgeon will give you advice based on your specific operation and recovery.

Will hemorrhoids come back after treatment?

Recurrence is possible after any treatment. It is more common after office procedures than after conventional surgery. Continuing fibre-rich diet, good bowel habits, and avoiding straining are the most important ways to reduce the chance of recurrence.

Can children get hemorrhoids?

Hemorrhoids are uncommon in children. When a child has anal bleeding or a perianal lump, doctors usually consider other causes first, such as anal fissures or rectal prolapse, and the child should be assessed by a paediatrician.

Is it safe to exercise with hemorrhoids?

Most forms of regular exercise are helpful, not harmful, because they support healthy bowel function. Activities involving very heavy lifting or prolonged straining may worsen symptoms in some people. After a procedure, your doctor will advise when to resume different types of exercise.

Do creams and ointments cure hemorrhoids?

Topical preparations help to relieve symptoms such as itching, pain, and inflammation, but they do not shrink established internal hemorrhoids on their own. They are best used as part of a broader plan that also addresses fibre, fluids, and bowel habits.

Conclusion

Hemorrhoids are common, treatable, and rarely dangerous, but they can significantly affect daily life when symptoms persist. Care follows a stepwise approach: simple changes to diet and bowel habits for most people, office-based procedures for those who do not improve, and surgery for advanced or persistent cases. The specific path depends on the type and grade of hemorrhoids, the symptoms, and the patient’s overall health.

Because hemorrhoids tend to recur if the underlying triggers continue, long-term habits — enough fibre, enough fluids, avoiding straining, and not spending too long on the toilet — are as important as any procedure. A clear conversation with your doctor or surgeon about the benefits and trade-offs of each option will help you arrive at a plan that fits your situation.
