Hemorrhoid
Vascular cushions in the anal canal that can become diseased.
Hemorrhoids, also known as piles, are vascular structures in the anal canal that normally function as cushions to help with stool control. They become a disease when swollen or inflamed, and the term hemorrhoid is often used to refer to this pathological condition.

Lore & Background
Hemorrhoids are classified as internal or external based on their location relative to the pectinate line. Internal hemorrhoids originate above the pectinate line and are covered by columnar epithelium lacking pain receptors; they often present with painless, bright red rectal bleeding. External hemorrhoids occur below the pectinate line and are covered by pain-sensitive skin, often causing pain and swelling. Internal hemorrhoids are graded I to IV based on prolapse severity, from no prolapse to irreducible prolapse.
Reader's Guide
Hemorrhoids are a common condition, affecting approximately 50% to 66% of people at some point in life, with peak occurrence between ages 45 and 65. While often self-limiting, they can cause significant discomfort and embarrassment, leading many to delay seeking care. Diagnosis is typically made by physical examination, including anoscopy or digital rectal exam, and serious causes such as colorectal cancer must be ruled out. Initial treatment focuses on conservative measures like increased fiber intake, hydration, NSAIDs, and rest. For severe or persistent cases, minimally invasive procedures such as hemorrhoidal artery embolization (HAE) and laser hemorrhoidoplasty (LHP) are available, with LHP showing improved short-term outcomes over conventional hemorrhoidectomy. Surgery is reserved for cases that fail to improve.
Did You Know?
- Approximately 50% to 66% of people have problems with hemorrhoids at some point in their lives.
- Internal hemorrhoids often result in painless, bright red rectal bleeding, while external hemorrhoids often cause pain and swelling.
- Laser hemorrhoidoplasty (LHP) is associated with less postoperative pain and faster recovery compared with conventional hemorrhoidectomy.
Frequently Asked Questions
Who is Hemorrhoid?
Hemorrhoids are vascular cushions sitting in the anal canal whose healthy job is to act as padding for stool control. They only cross into 'disease' territory once they swell or become inflamed, and that pathological state is what most people actually mean by the word.
What is Hemorrhoid's original role in the body?
In their natural, undiseased form they function as soft cushions within the anal canal, helping the body maintain a proper seal and control over bowel movements. They are a built-in anatomical feature, not an external invader.
Who does Hemorrhoid typically target, and what triggers its appearance?
Roughly half to two-thirds of all people will encounter it at some point, with the highest incidence between ages 45 and 65 and hitting males and females about equally. Common triggers include constipation, diarrhea, long stretches sitting on the toilet, pregnancy, a low-fiber diet, and obesity.
How does Hemorrhoid's story typically resolve?
Mild episodes often settle on their own or with simple lifestyle tweaks such as adding fiber and cutting down on straining. More stubborn or severe cases may call for medical steps ranging from topical treatments to minor surgical procedures.
