Internal piles form inside the rectum and usually cause painless bleeding, while external piles develop under the skin around the anus and cause pain, swelling, and itching. The key difference between internal vs external piles is location, which shapes both symptoms and treatment. Understanding this distinction helps you seek the right care early. In this article, we explain what each type is, their symptoms, causes, complications, and the treatment options available at Lux Hospitals. Read on to recognise the warning signs and know when to consult a specialist.
What Are Piles?
Piles, also called haemorrhoids, are swollen blood vessels in and around the anus and lower rectum. They are extremely common and often linked to straining during bowel movements.
Piles are broadly grouped by location. This location determines the type and how they behave:
- Internal piles — inside the rectum
- External piles — under anal skin
- Prolapsed piles — internal piles that slip out
- Thrombosed piles — clotted, painful lumps

What Are Internal Piles?
Internal piles develop above the dentate line, deep inside the rectum where there are few pain-sensing nerves. This is why they are often painless.
They are graded by how much they protrude. Internal piles are commonly classified as:
- Grade 1 — no prolapse, only bleeding
- Grade 2 — prolapse that self-reduces
- Grade 3 — prolapse needing manual pushing
- Grade 4 — permanently prolapsed
What Are External Piles?
External piles form below the dentate line, under the sensitive skin surrounding the anus. Because this area is rich in nerves, they are usually painful.
They may appear as visible lumps and can become thrombosed. You may notice:
- Firm lumps around the anus
- Pain when sitting or wiping
- Itching and irritation
- Sudden bluish swelling if clotted
Painful anal lumps shouldn't be ignored—get expert evaluation at Lux Hospitals.
Key Differences Between Internal and External Piles
The main distinction in internal vs external piles comes down to location, sensation, and appearance. Both share causes but differ in how they feel.
Here are the core differences to remember:
- Internal — inside rectum, usually painless
- External — under anal skin, often painful
- Internal — painless bleeding is the main sign
- External — visible lumps and swelling
- Internal — graded by prolapse; external — not graded
Symptoms of Internal Piles
Internal piles often go unnoticed until bleeding appears. Since they sit in a low-nerve area, discomfort is minimal in early stages.
Common symptoms may include:
- Bright red blood during bowel movements
- Mucus discharge after passing stool
- A feeling of incomplete emptying
- Lump protruding in advanced grades
- Mild itching around the anus

Symptoms of External Piles
External piles are far more noticeable because of the pain and visible swelling they cause. They can interfere with sitting and daily comfort.
Symptoms may include:
- Pain or aching around the anus
- Swelling and tender lumps
- Itching and burning sensation
- Difficulty cleaning the area
- Severe pain if thrombosed
Common Causes and Risk Factors
Both internal and external piles share similar triggers, mostly linked to pressure in the lower rectum. Lifestyle plays a major role.
Common causes and risk factors include:
- Chronic constipation and straining
- Low-fibre diet and dehydration
- Prolonged sitting on the toilet
- Pregnancy and obesity
- Ageing and heavy lifting

Possible Complications of Untreated Piles
Ignoring piles can lead to worsening symptoms and complications. Persistent bleeding may cause anaemia over time.
Untreated piles may lead to:
- Anaemia from chronic blood loss
- Thrombosis causing severe pain
- Strangulated prolapsed piles
- Infection or skin tags
- Confusion with an anal fissure
How Piles Are Diagnosed
Diagnosis begins with a review of symptoms and a physical examination. Internal piles often need instruments to visualise them.
Typical diagnostic steps include:
- Visual inspection of the anal area
- Digital rectal examination
- Proctoscopy for internal piles
- Colonoscopy to rule out other causes
- Assessment for anal fistula or polyps
