Introduction
Hemorrhoids, commonly called piles, are swollen veins in the lower rectum and anus. They're extremely common — most adults will experience symptomatic hemorrhoids at some point — and in the large majority of cases, they're very manageable once properly diagnosed and graded. At KAGE, hemorrhoids are evaluated alongside a check for other, more serious causes of similar symptoms, particularly rectal bleeding, rather than assumed from symptoms alone.
How common are hemorrhoids, and what actually causes them
Hemorrhoids are one of the most frequently diagnosed anorectal conditions, with global prevalence estimates ranging widely depending on the population studied — up to around 40% of adults in some data. Indian clinical studies point clearly to which risk factors matter most locally: in one tertiary-center study, chronic constipation was present in 57.5% of patients with hemorrhoidal disease, low dietary fiber intake in 69.6%, and a sedentary lifestyle in 59.6% — all significantly associated with more severe disease. Unlike some risk factors for other conditions, these are largely modifiable, which is part of why lifestyle change is the foundation of treatment, not just an afterthought.
Internal vs. external hemorrhoids
- Internal hemorrhoids — form inside the rectum, often painless, and typically the ones that cause bleeding; they're graded I through IV based on severity
- External hemorrhoids — form under the skin around the anus, and are more likely to cause pain, itching, or a noticeable lump, particularly if a blood clot forms within them (thrombosis)
Grading internal hemorrhoids
Grading is what actually determines treatment — not simply the presence of hemorrhoids:
| Grade | What it means | Typical treatment |
|---|---|---|
| Grade I | Bleed but don't prolapse (protrude) | Diet, fiber, and lifestyle changes |
| Grade II | Prolapse with straining, return on their own | Lifestyle changes, often combined with banding or sclerotherapy |
| Grade III | Prolapse and need to be pushed back manually | Banding, sclerotherapy, or surgical referral depending on severity |
| Grade IV | Permanently prolapsed, can't be pushed back | Usually needs surgical hemorrhoidectomy |
Symptoms of hemorrhoids
- Bright red bleeding, often noticed on toilet paper or in the toilet bowl
- Itching or irritation around the anus
- A lump or swelling near the anus, sometimes tender
- Discomfort or pain, particularly with external hemorrhoids or thrombosis
- A feeling of incomplete evacuation, in more advanced cases
What causes hemorrhoids
- Chronic constipation and straining during bowel movements — the strongest and most consistent risk factor in Indian studies
- A low-fiber diet
- Sedentary lifestyle and prolonged sitting
- Pregnancy
- Obesity
- Chronic diarrhea, in some cases
- A family history of hemorrhoids
How hemorrhoids are diagnosed
- Physical examination — often sufficient to identify external hemorrhoids and grade internal ones on straining
- Anoscopy — a focused examination of the anal canal for a clearer view of internal hemorrhoids
- Colonoscopy — recommended when bleeding needs to be properly investigated, particularly in patients over 45–50 or with other risk factors, to rule out more serious causes such as colon polyps or colorectal cancer before attributing bleeding to hemorrhoids
Hemorrhoid treatment: matched to grade
- For Grade I–II: increased dietary fiber, adequate hydration, avoiding straining, and topical treatments for symptom relief — often sufficient on their own
- For persistent Grade II or III: office-based procedures such as rubber band ligation or sclerotherapy, which are quick, effective, and don't require surgery
- For Grade IV or large Grade III hemorrhoids not responding to the above: surgical hemorrhoidectomy is generally the definitive treatment
- For thrombosed external hemorrhoids: management depends on timing and severity, ranging from conservative pain control to a minor procedure to remove the clot
Hemorrhoid care at KAGE
Rectal bleeding is often hemorrhoids, but it is never assumed to be — our gastroenterologists examine, and scope where age or symptoms warrant it, before attributing bleeding to piles. Treatment then starts with the least invasive option that works: banding and other office procedures for most patients, with surgery reserved for those they do not settle. To have bleeding checked rather than watched, book a consultation.
Frequently asked questions
Yes, in most cases. Grade I and II, and many Grade III hemorrhoids, respond well to dietary changes, lifestyle changes, and office-based procedures like rubber band ligation, without needing surgery.
Internal hemorrhoids form inside the rectum and are often painless, mainly causing bleeding. External hemorrhoids form under the skin around the anus and are more likely to cause pain, itching, or a noticeable lump.
A high-fiber diet with plenty of fruits, vegetables, and whole grains, along with adequate water intake, is the single most effective dietary change for both preventing and managing hemorrhoids.
Consultation and standard procedures like banding are generally covered under most health insurance plans; coverage for surgical treatment depends on your specific policy. Our team can help verify coverage during consultation.
It's generally well-tolerated, with mild discomfort rather than significant pain for most patients, and is done as a quick outpatient procedure without the recovery time associated with surgery.
Mild, Grade I hemorrhoids can improve with diet and lifestyle changes alone. More advanced grades usually need some form of treatment to resolve rather than resolving completely by themselves.
Yes, particularly if the underlying risk factors like constipation and low fiber intake aren't addressed. Ongoing dietary and lifestyle changes meaningfully reduce the chance of recurrence.
Yes — increased pressure on pelvic veins during pregnancy is a well-recognized risk factor, and hemorrhoids often improve after delivery, though they may still need management in the meantime.
Surgery is generally reserved for Grade IV hemorrhoids, or large Grade III hemorrhoids that haven't responded to other treatments — it's not the first-line approach for most patients.
It's uncommon in children and usually linked to a specific cause like chronic constipation; pediatric cases are evaluated by KAGE's pediatric gastroenterology team.
