How Common Are Piles?

Hemorrhoids, often called piles, are far more common than most people realize. Research estimates that about 1 in 20 Americans has symptomatic hemorrhoids at any given time, and roughly half of all people will experience them by age 50. This means millions of adults deal with piles each year, making it one of the most frequent medical conditions affecting the digestive system.

What Exactly Are Piles and Who Gets Them?

Piles are swollen veins in the lower rectum and anus. They are essentially varicose veins in a sensitive area. There are two main types: internal piles, which form inside the rectum, and external piles, which develop under the skin around the anus.

Age is the strongest risk factor. Studies have found that the prevalence of hemorrhoids increases steadily with age, peaking between ages 45 and 65. After age 50, the supporting tissues in the anal canal naturally weaken, making veins more likely to bulge and swell.

Pregnancy also significantly increases the risk. About 25 to 35 percent of pregnant women develop piles, especially during the third trimester. The growing uterus puts pressure on pelvic veins, and hormonal changes relax the vein walls. For most women, these pregnancy-related piles resolve after childbirth.

How Common Are Piles Across Different Populations?

Current research suggests that piles affect people of all backgrounds, but some groups report higher rates. Studies from the United States indicate that hemorrhoids are diagnosed more often in white adults than in Black or Hispanic adults, though this may reflect differences in healthcare access rather than true biological differences.

Income and education also play a role. People with higher socioeconomic status report piles more frequently. This is likely because they have better access to healthcare and are more willing to discuss the condition with a doctor. Many people with piles never seek medical help, so official numbers probably underestimate the true rate.

Obesity is another clear risk factor. A large study published in the American Journal of Gastroenterology found that people with a body mass index over 30 had a significantly higher chance of developing hemorrhoids. Excess abdominal weight increases pressure on the veins in the pelvis.

What Causes Piles to Form in the First Place?

The direct cause is increased pressure in the veins of the lower rectum. This pressure can come from several sources. Chronic constipation is the most common trigger. Straining during bowel movements forces blood vessels to swell and stretch.

Sitting on the toilet for long periods also contributes. When you sit, the veins in your anal area have to work against gravity. Spending more than 10 minutes on the toilet regularly raises the pressure enough to cause problems over time.

A low-fiber diet is strongly linked to piles. Fiber helps keep stool soft and easy to pass. Without enough fiber, stool becomes hard and dry, leading to constipation and straining. Studies have shown that increasing fiber intake reduces the risk of developing hemorrhoids by about 50 percent.

Heavy lifting is a less common but real cause. People who regularly lift heavy objects at work or in the gym may experience temporary increases in abdominal pressure that strain the anal veins.

What Does the Evidence Say About Symptoms and Diagnosis?

Most people with piles have no symptoms at all. Many are discovered during routine physical exams. When symptoms do occur, the most common is bright red blood on toilet paper or in the toilet bowl after a bowel movement. This bleeding is usually painless with internal piles.

External piles are more likely to cause discomfort. They can feel like a hard lump near the anus. If a blood clot forms inside an external pile, it becomes a thrombosed hemorrhoid, which causes sudden, severe pain and swelling. This type typically resolves on its own within a week but can be very uncomfortable.

Doctors diagnose piles through a simple physical exam. For internal piles, they may use an anoscope, which is a short tube with a light. A colonoscopy is sometimes recommended to rule out other causes of rectal bleeding, especially in people over 45. This is important because colon cancer can cause similar bleeding.

What Treatments Actually Work?

For mild piles, simple lifestyle changes are very effective. Increasing fiber to 25 to 30 grams per day softens stool and reduces straining. Over-the-counter creams and suppositories containing hydrocortisone can reduce swelling and itching for short-term relief. But these should not be used for more than a week without a doctor’s guidance.

For persistent or severe piles, in-office procedures are available. Rubber band ligation is the most common. A doctor places a small rubber band around the base of the internal pile, cutting off its blood supply. The pile shrinks and falls off within a week. This procedure works well for about 80 percent of people.

Surgery is reserved for the worst cases. Hemorrhoidectomy removes the pile surgically. It has the highest success rate but also the longest recovery time and more pain afterward. As of 2026, newer techniques like laser and stapled hemorrhoidopexy offer less painful alternatives, though evidence on long-term outcomes is still developing.

Common Misconceptions About Piles

One widespread myth is that spicy food causes piles. There is no clinical evidence that eating spicy foods creates hemorrhoids. Spicy foods can irritate existing piles and make symptoms feel worse, but they do not cause the veins to swell in the first place.

Another misconception is that piles are a sign of poor hygiene. This is not true. In fact, excessive cleaning with harsh soaps or wipes can irritate the area and make symptoms worse. Gentle cleaning with warm water is usually enough.

Many people believe that piles always require surgery. This is false. The vast majority of piles improve with diet changes, fiber supplements, and simple lifestyle adjustments. Only about 5 to 10 percent of people with symptomatic hemorrhoids ever need surgical treatment.

What to Avoid When You Have Piles

Avoid sitting on the toilet for more than 5 minutes. This is one of the simplest and most effective changes you can make. Bring nothing to read. Do not scroll on your phone. The longer you sit, the more pressure builds in the anal veins.

Do not use laxatives regularly unless a doctor recommends them. Some laxatives can cause diarrhea, which irritates piles just as much as constipation. The goal is soft, formed stool, not loose stool.

Avoid heavy lifting during flare-ups. If you must lift something heavy, exhale while lifting to reduce internal pressure. Holding your breath while lifting increases abdominal pressure and can worsen piles.

Avoid alcohol and caffeine in excess. Both can lead to dehydration, which makes stool harder and increases the need to strain. Staying well hydrated is one of the simplest preventive measures.
