hemorrhoids

Overview
Hemorrhoids, also known as piles, are swollen veins in the lower rectum or anus. They occur when increased pressure causes veins to stretch and bulge, often leading to discomfort, itching, or bleeding during bowel movements. Hemorrhoids can be internal (inside the rectum) or external (under the skin around the anus). While common and usually not dangerous, they can significantly impact daily comfort.

Why It’s Important
Hemorrhoids can cause pain, bleeding, and irritation, which can interfere with sitting, bowel movements, and overall quality of life. Persistent or severe hemorrhoids may indicate underlying conditions such as chronic constipation or anal fissures. Managing symptoms early helps prevent complications and improves comfort.

Quick Facts

  • Affect roughly 75% of adults at some point in their life

  • More common in adults over 45, pregnant individuals, and those with chronic constipation

  • Can be acute (flare-ups) or chronic

  • Classified as internal or external, sometimes thrombosed (blood clots form)

What Happens in the Body
Hemorrhoids form when veins in the rectal or anal area become swollen due to increased pressure. Common causes include straining during bowel movements, prolonged sitting, pregnancy, obesity, or heavy lifting. Internal hemorrhoids may protrude outside the anus (prolapse), while external hemorrhoids can form painful clots (thrombosis).

Common Signs and Symptoms

  • Bright red blood on toilet paper or in the toilet

  • Itching, irritation, or discomfort around the anus

  • Swelling or a lump near the anus

  • Pain or soreness, especially with external or thrombosed hemorrhoids

  • Mucus discharge or difficulty cleaning the area

Diagnosis

  • Physical examination by a healthcare provider

  • Digital rectal exam for internal hemorrhoids

  • Anoscopy or sigmoidoscopy if necessary to rule out other causes of bleeding

  • Review of bowel habits and medical history

Treatment and Management

  • Lifestyle changes: High-fiber diet, increased water intake, regular exercise, avoiding straining during bowel movements

  • Medications: Over-the-counter creams, ointments, or suppositories to reduce swelling and discomfort

  • Procedures: Rubber band ligation, sclerotherapy, or surgical removal for severe or persistent hemorrhoids

  • Most cases are manageable with lifestyle adjustments and temporary treatments

Risks and Complications

  • Anemia from chronic blood loss (rare)

  • Thrombosed hemorrhoids causing severe pain

  • Persistent swelling or prolapse requiring surgical intervention

  • Skin irritation or infection from prolonged discomfort

Who Is at Risk

  • People with chronic constipation or diarrhea

  • Pregnant individuals (due to increased abdominal pressure)

  • Obese individuals or those with sedentary lifestyles

  • Those who lift heavy objects frequently

  • Older adults as veins weaken with age

Related Conditions

  • Anal fissures

  • Rectal prolapse

  • Colorectal conditions causing rectal bleeding

  • Chronic constipation or straining

When to See a Doctor
Seek medical attention if you experience:

  • Severe pain or swelling

  • Heavy or persistent rectal bleeding

  • Hemorrhoids that do not improve with home treatment

  • Signs of infection (redness, pus, fever)

  • Any new rectal bleeding to rule out other serious conditions
