Hemorrhoids (Piles): Causes, Symptoms, Types & Effective Treatments

Hemorrhoids, also known as piles, occur when the anus veins and lower rectum become swollen and enlarged, leading to discomfort, pain, and rectal bleeding. While everyone has hemorrhoidal tissue naturally, problems arise only when these veins swell and cause symptoms. Similar to varicose veins, hemorrhoids can develop internally within the rectum (internal hemorrhoids) or externally under the skin around the anus (external hemorrhoids). Fortunately, various treatment options exist, ranging from home remedies and lifestyle adjustments to medical interventions, helping many individuals find relief.

Types

There are three different types of hemorrhoids: Internal, External, and Thrombosed Piles.

Internal Piles

Internal hemorrhoids develop deep inside the rectum, making them invisible and difficult to detect. Since this area has very few pain-sensing nerves, they typically don’t cause pain. However, their presence can lead to other symptoms, such as bleeding or discomfort, especially if they become irritated or enlarged.

External Piles

External hemorrhoids develop in the anal area, often causing discomfort. When they protrude through the anus, they become visible and can be felt. In some cases, blood clots may form within the swollen mass, leading to severe pain, especially if the hemorrhoid slips downward.

Thrombosed Piles

When blood collects in an external hemorrhoid, it can form a clot known as a thrombus. It can cause intense pain, swelling, inflammation, and a firm, discolored lump near the anus.

Symptoms

In most cases, hemorrhoid symptoms are mild and resolve without treatment. However, individuals with hemorrhoids may experience symptoms such as:

• Painful lumps in and around the anus
• Itching and irritation in the anal area
• Discomfort during and after bowel movements
• Blood in the stool

In some instances, hemorrhoids can worsen and lead to serious complications, including:

• Excessive anal bleeding, which may cause anemia
• Infections
• Fecal incontinence
• Anal fistulas
• Strangulated hemorrhoids, where the anal muscles restrict blood flow to the swollen tissue

Despite these potential complications, many people with hemorrhoids experience no noticeable symptoms.

Causes

Straining puts pressure on the veins in the anus or rectum, causing hemorrhoids. Increased pressure on the abdomen or lower extremities is prone to inflammation and swelling of the anal and rectal veins. Hemorrhoids may develop due to:

• Pushing hard to have a bowel movement due to constipation.
• Pelvic pressure from weight gain, especially during pregnancy.
• Straining to lift heavy objects or weightlifting.

Diagnosis

Doctors diagnose hemorrhoids by reviewing symptoms and performing a physical examination. External hemorrhoids can often be identified by simply examining the area around the anus.

A digital rectal examination may be done to check for internal hemorrhoids. In this test, the doctor gently inserts a gloved and lubricated finger into the rectum to feel for swelling or abnormalities.

If further evaluation is needed, procedures such as anoscopy, proctoscopy, or sigmoidoscopy may be used to view the rectum and anal canal more clearly. In some cases, a colonoscopy is recommended to rule out other digestive conditions.

These tests are usually quick, safe, and performed on an outpatient basis.

Treatment

Hemorrhoid treatment aims to reduce pain, swelling, itching, and bleeding. The treatment depends on how severe the condition is. Many mild cases improve with home care, while persistent or severe hemorrhoids may require medical procedures.

Home and Lifestyle Care

Simple measures can help relieve symptoms and prevent worsening:

• Eat fiber-rich foods such as fruits, vegetables, and whole grains to soften stools.
• Drink enough water to prevent constipation.
• Take warm sitz baths for 10–20 minutes to soothe irritation.
• Apply cold compresses to reduce swelling.
• Avoid straining and scratching the affected area.
• Use a small stool under your feet while using the toilet to make bowel movements easier.
• Natural soothing agents like coconut oil may help reduce irritation.

Medicines

Doctors may suggest medications to control discomfort:

• Over-the-counter creams, ointments, and soothing pads to relieve pain and itching.
• Corticosteroid creams to reduce inflammation (short-term use only).
• Pain relievers for temporary discomfort.
• Stool softeners or laxatives if constipation is present.

Minimally Invasive Procedures

If symptoms continue, simple outpatient procedures may be recommended:

• Rubber band ligation: Cuts off blood supply so the hemorrhoid shrinks.
• Sclerotherapy: A chemical injection reduces the swollen vein.
• Infrared or electrical coagulation: Heat or light is used to shrink hemorrhoid tissue.
• Thrombectomy: Removal of a painful clot from an external hemorrhoid.

Surgical Treatment

Surgery is considered for large or severe hemorrhoids:

• Hemorrhoidectomy: Surgical removal of hemorrhoids.
• Stapled hemorrhoidopexy: Pulls prolapsed hemorrhoids back into place.
• Transanal hemorrhoidal dearterization (THD): Ties off blood vessels supplying the hemorrhoid.

Seek medical advice if symptoms are severe, cause bleeding, disturb daily activities, or do not improve after a week of home treatment.
