Hemorrhoids (Piles): Causes, Symptoms, Diagnosis & Treatment

Hemorrhoids, commonly known as piles, are swollen and inflamed veins in the anal canal and rectum. They are a very common anorectal condition and can affect people of all ages. Although uncomfortable and sometimes painful, hemorrhoids are not dangerous and are usually treatable with lifestyle changes and medical care.

 What Are Hemorrhoids?

Veins in the anal region normally help with continence.
When pressure in these veins increases, they become enlarged and inflamed, leading to hemorrhoids.

 Causes & Risk Factors

Hemorrhoids develop due to increased pressure in the rectal veins. Common causes include chronic constipation, prolonged straining during bowel movements, sitting for long periods, low-fiber diet, obesity, pregnancy, and aging. These factors weaken the venous walls and lead to swelling and inflammation. 

Hemorrhoids develop due to increased pressure in the rectal veins.

🔹 Common Causes

• Chronic constipation

• Straining during bowel movements

• Prolonged sitting on the toilet

• Low-fiber diet

• Inadequate water intake

• Chronic diarrhea

🔹 Other Risk Factors

-Pregnancy

Increased pelvic pressure

-Obesity

Increased abdominal pressure

-Sedentary lifestyle

Poor bowel movement

-Heavy lifting

Increased intra-abdominal pressure

-Aging

Weakening of supporting tissues

 Types of Hemorrhoids

1.Internal hemorrhoids

Located inside rectum; usually painless

2.External hemorrhoids

Located under skin around anus; painful

3.Prolapsed hemorrhoids

Internal piles protruding outside

4.Thrombosed hemorrhoids

External hemorrhoids with blood clot

 Symptoms

Symptoms vary depending on the type. Internal hemorrhoids often present with painless rectal bleeding during defecation, while external hemorrhoids may cause pain, swelling, itching, and discomfort around the anus. Some individuals may also feel a lump or experience irritation and mucus discharge.

Internal Hemorrhoids

• Painless bright red bleeding during defecation

• Blood on toilet paper or stool

• Mucus discharge

• Prolapse in advanced stages

External Hemorrhoids

• Pain or discomfort around anus

• Swelling or lump near anal opening

• Itching or irritation

• Difficulty sitting

 Urgent Symptoms

• Severe pain with swelling

• Continuous bleeding

• Black stools (rule out other causes)

• Fever with anal pain (possible infection)

 Grading of Internal Hemorrhoids

Grade I

Bleeding only

Grade II

Prolapse during defecation, reduces spontaneously

Grade III

Prolapse requiring manual reduction

Grade IV

Permanently prolapsed

Diagnosis

Diagnosis is usually made based on clinical examination. External hemorrhoids can be identified by physical inspection, while internal hemorrhoids may require digital rectal examination, anoscopy, or proctoscopy. Further investigations may be done to rule out other causes of rectal bleeding. 

Diagnosis is usually clinical.

Investigations

• Physical examination

• Digital rectal examination

• Proctoscopy / anoscopy

• Colonoscopy (if red-flag symptoms or age > 50)

 Treatment & Management

Management depends on severity. Mild cases are treated with lifestyle modifications such as increased fiber intake, adequate hydration, and avoidance of straining. Medications like topical creams, stool softeners, and pain relievers may be used. Severe cases may require procedures such as rubber band ligation, sclerotherapy, or surgery.

1️. Conservative (First Line)

Most early hemorrhoids improve with lifestyle measures.

• High-fiber diet (25–35 g/day)

• Adequate water intake (2–3 liters/day)

• Avoid straining

• Regular bowel habits

• Warm sitz baths

• Topical creams and suppositories

2️. Medical Treatment

1.Stool softeners

Reduce straining

2.Topical anesthetics

Pain relief

3.Anti-inflammatory ointments

Reduce swelling

4.Venotonics

Improve vein tone

 Prolonged use of steroid creams should be avoided.

3️. Procedural Treatment

Used for persistent or advanced hemorrhoids.

1.Rubber band ligation

Grade I–III

2.Sclerotherapy

Early hemorrhoids

3.Infrared coagulation

Bleeding piles

4,Hemorrhoidectomy

Grade III–IV

5.Stapled hemorrhoidopexy

 Complications if Untreated

If untreated, hemorrhoids may lead to complications such as thrombosis (clot formation), persistent bleeding, anemia, or prolapse of internal hemorrhoids. Early management helps prevent these issues. 

• Chronic bleeding → anemia

• Thrombosis

• Prolapse

• Infection (rare)

• Reduced quality of life

 Prevention

Preventive measures include maintaining a high-fiber diet, drinking sufficient water, avoiding prolonged sitting or straining, exercising regularly, and responding promptly to the urge to pass stool. These habits help maintain normal bowel function and reduce pressure on rectal veins.

• Maintain regular bowel habits

• Do not ignore urge to defecate

• Avoid prolonged sitting on toilet

• Increase fiber and water intake

• Exercise regularly

• Maintain healthy body weight

 When to Consult a Doctor

• Recurrent or heavy rectal bleeding

• Severe pain or swelling

• Prolapsed hemorrhoids

• Symptoms not improving with home care

• Weight loss or anemia
