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.

🔹 Common Causes

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
Selected cases
Dietary Advice
recommended Avoid
Whole grains
Refined flour foods
Fruits & vegetables
Low-fiber diet
Psyllium husk
Excess spicy foods
Adequate fluids
Alcohol
Regular meals
Skipping meals
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
