Hemorrhoid
Vascular cushions in the anal canal that can become diseased.
Hemorrhoids, also known as piles, are vascular structures within the anal canal that, in their normal state, function as cushions aiding in stool control. They become a pathological disease when these structures become swollen or inflamed. The condition is remarkably common, affecting an estimated half to two-thirds of people at some point in their lives, with men and women experiencing it at roughly equal rates. It is most frequently seen in individuals between the ages of 45 and 65, and it is reported more often among wealthier populations, though this may be due to differences in healthcare access rather than actual prevalence. The earliest known mention of the disease dates back to an Egyptian papyrus from 1700 BC.
Symptoms vary depending on the type. Internal hemorrhoids typically cause painless, bright red rectal bleeding during or after a bowel movement, with blood often seen on the stool, toilet paper, or in the toilet bowl. External hemorrhoids, by contrast, frequently cause pain and swelling around the anus; any bleeding from them is usually darker. While symptoms often improve within a few days, a skin tag may remain after an external hemorrhoid heals. Many people with the condition experience no significant symptoms at all. Bleeding severe enough to cause anemia is rare, and life-threatening bleeding is even more uncommon. People often feel embarrassed and may delay seeking medical care until the condition is advanced.
The exact cause remains unknown, but factors that increase abdominal pressure are believed to contribute, including constipation, diarrhea, prolonged sitting on the toilet, and pregnancy. Diagnosis is made by visual examination, though serious causes of anal symptoms must be ruled out, often via colonoscopy or sigmoidoscopy. For most, no specific treatment is needed; initial management includes increased fiber intake, adequate hydration, pain relief with NSAIDs, and rest. Medicated creams are commonly used, but evidence for their effectiveness is weak. For severe or persistent cases, minimally invasive procedures such as hemorrhoidal artery embolization or laser hemorrhoidoplasty are options. Surgery is reserved for cases that do not improve with other measures.

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.
