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 vascular structures within the anal canal that, in their normal state, function as cushions aiding stool control. They become a disease when swollen or inflamed, and the term is commonly used to refer to this pathological condition. The first known mention of the disease dates to a 1700 BC Egyptian papyrus. Approximately 50 to 66 percent of people experience hemorrhoids at some point, with equal frequency in males and females, most often between ages 45 and 65; they are more common among the wealthy, though this may reflect healthcare access rather than true prevalence. The exact cause remains unknown, but factors increasing abdominal pressure—such as constipation, diarrhea, prolonged sitting on the toilet, and pregnancy—are believed involved. Other contributing factors include lack of exercise, low-fiber diets, obesity, chronic cough, and aging. During pregnancy, pressure from the fetus and hormonal changes enlarge hemorrhoidal vessels, though symptoms usually resolve after delivery. Diagnosis is made by visual examination; colonoscopy or sigmoidoscopy may confirm the diagnosis and rule out more serious causes. Many people mistakenly refer to any anal symptom as hemorrhoids, so serious causes must be excluded. Often no specific treatment is needed; initial measures include increased fiber intake, fluids, NSAIDs for pain, and rest. Medicated creams are used but have poor evidence of effectiveness. For severe cases, minor procedures exist, including hemorrhoidal artery embolization and laser hemorrhoidoplasty, the latter associated with less postoperative pain and faster recovery than conventional surgery. Surgery is reserved for those who do not improve with other measures. Outcomes are generally good.
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.
