Grades of Piles: Grade 1 to Grade 4 Explained

If you have been told you have "Grade 2" or "Grade 3" piles, the terminology can feel confusing. What does a grade actually mean? Is a higher grade always serious? And does every grade require surgery?

Piles, also known as haemorrhoids, are extremely common. Many adults experience them at some point, especially during pregnancy, prolonged constipation, or long hours of sitting. In most cases, they are manageable.

This guide explains the grades of piles (Grade 1 to Grade 4) in simple language, so you understand what is happening inside your body and what it means for treatment.

Piles are swollen veins that are present near the lower rectum or around the anus. They develop when pressure in these veins increases, causing them to enlarge.

There are two main types:

• Internal piles – located inside the rectum

• External piles – located under the skin around the anus

Doctors use a grading system only for internal piles. External piles are not graded in the same way.

Common triggers include:

• Chronic constipation

• Straining during bowel movements

• Pregnancy

• Obesity

• Prolonged sitting

You can think of piles as similar to varicose veins, but in the anal region.

When doctors talk about grades of piles, they refer to how far the internal haemorrhoid has prolapsed, or slipped downward from its normal position.

The grading system focuses on:

• Whether the pile stays inside

• Whether it comes out during a bowel movement

• Whether it goes back in on its own

• Whether it needs to be pushed back

• Whether it remains permanently outside

There are four grades, and each one represents increasing severity of prolapse, not necessarily increasing pain.^[1]

Grade 1

• The pile remains inside the rectum.
• There is no visible prolapse outside the anus.

You may notice:

• Painless bleeding during bowel movements
• Bright red blood on toilet paper
• Mild discomfort or itching

At this stage, many people do not even realise they have piles until they see bleeding.

Grade 2

• The pile comes out during straining or bowel movement.
• It goes back inside on its own afterwards.

Symptoms may include:

• Bleeding
• Mucus discharge
• A feeling of incomplete evacuation

For example, you may feel something bulging briefly during a bowel movement, but it disappears without effort.

Grade 3

• The pile comes out during a bowel movement.
• It does not go back in on its own.
• You must push it back manually.

Symptoms often include:

• More noticeable prolapse
• Discomfort while sitting
• Irritation or swelling

This grade is typically when patients seek medical advice because the prolapse becomes more obvious and bothersome.

Grade 4

• The pile remains permanently outside.
• It cannot be pushed back in.

Symptoms may include:

• Persistent discomfort
• Pain (especially if the blood supply is compromised)
• Swelling
• Risk of complications

Grade 4 piles may significantly interfere with daily activities and usually require procedural treatment.

Regardless of the grade, piles symptoms may include:

• Bright red bleeding during bowel movement

• Itching around the anus

• Discomfort while sitting

• Swelling

• Mucus discharge

Pain is not always present. Internal piles are often painless unless complications develop.

If you experience severe pain, sudden swelling, or heavy bleeding, medical evaluation is important to rule out other conditions.

Not necessarily.

Many Grade 1 and some Grade 2 piles improve with conservative management, such as:

• Increased fibre intake

• Adequate hydration

• Avoiding straining

• Shorter time spent on the toilet

Doctors typically recommend treatment based on:

• Severity of symptoms

• Frequency of bleeding

• Degree of prolapse

• Impact on quality of life

The grade helps guide decisions, but symptoms matter just as much.

Here are the common treatments for piles depending on severity. Remember to always consult your doctor about treating your pile, not just rely on home remedies.

Conservative management (mostly Grade 1 and early Grade 2)

• Dietary fibre supplements^[2]

• Stool softeners

• Warm sitz baths

• Topical medications

Office-based procedures (often Grade 2 and some Grade 3)

• Rubber band ligation

• Sclerotherapy

• Infrared coagulation

These procedures are minimally invasive and usually performed without major surgery.

Surgical or Advanced Procedures (Grade 3 and Grade 4)

When prolapse is significant or recurrent, surgery may be recommended. One advanced option is stapled haemorrhoidopexy, performed using devices such as the MIRUS™ HAEMORRHOIDS STAPLER. This technique:

• Repositions prolapsed tissue

• Reduces blood flow to haemorrhoids

• Causes less postoperative pain compared to conventional excisional surgery

• Supports faster recovery in appropriate cases

The choice of procedure depends on patient evaluation and clinical judgement.

While many piles remain manageable, untreated severe cases may lead to:

• Anaemia due to chronic blood loss

• Thrombosed haemorrhoids (painful blood clots)

• Strangulated piles, where the blood supply is cut off

• Persistent prolapse

• Skin irritation and infection

These complications are not common, but they become more likely with advanced grades.

Persistent bleeding should always be evaluated to rule out other causes, such as colorectal conditions.

Prevention focuses on reducing pressure in the rectal veins. Practical steps include:

• Eating fibre-rich foods (vegetables, fruits, whole grains)

• Drinking sufficient water

• Avoiding prolonged sitting

• Not delaying bowel movements

• Avoiding excessive straining

• Maintaining a healthy weight

If you have early-stage piles, these steps can prevent progression to higher grades.

Understanding the grades of piles from Grade 1 to Grade 4 helps you interpret your diagnosis clearly.

• Grades 1 and 2 are often manageable with lifestyle changes and minor procedures.

• Grades 3 and 4 involve significant prolapse and may require surgical intervention.

The grade indicates how much the haemorrhoid has prolapsed, not necessarily how severe your discomfort will be. Early consultation allows timely management and reduces the risk of complications.

If you notice bleeding, persistent swelling, or prolapse, seeking medical advice ensures proper diagnosis and appropriate treatment.
