Hemorrhoids are swollen blood vessels in and around the anus and lower rectum, and they are one of the most common reasons adults notice bleeding, itching, or discomfort during a bowel movement. They are also one of the most under-discussed conditions, because the area feels private and even a little embarrassing. That silence is unfortunate, because hemorrhoids are extremely common, usually harmless, and very treatable once you understand what is happening. In this article you’ll learn what hemorrhoids are, why they develop, how to tell internal from external ones, which treatments actually help, and how to know when bleeding deserves a closer look rather than a guess. Along the way, we explain the lab tests that can matter when symptoms do not settle.

What Are Hemorrhoids?

Everyone has hemorrhoidal tissue. These are normal cushions of blood vessels, connective tissue, and small muscle fibers that sit in the anal canal and help control continence. Problems begin when these cushions become swollen, stretched, or slip out of place. When people say they “have hemorrhoids,” they mean this swollen, symptomatic version of otherwise normal anatomy.

Doctors sort hemorrhoids by where they form relative to the dentate line, an invisible border inside the anal canal that separates tissue with many pain nerves from tissue with very few. That single detail explains why some hemorrhoids hurt and others do not, and it guides which treatment is likely to work.

Internal Hemorrhoids

Internal hemorrhoids develop above the dentate line, inside the rectum, where there are few pain-sensing nerves. As a result, they often cause painless bleeding rather than pain. Their most common sign is bright-red blood on the toilet paper, coating the stool, or dripping into the bowl. Larger internal hemorrhoids can bulge out of the anus, a change called prolapse.

External Hemorrhoids

External hemorrhoids form below the dentate line, under the sensitive skin around the anal opening. Because this skin is rich in nerves, external hemorrhoids are more likely to itch, swell, and hurt. If a blood clot forms inside one, it becomes a thrombosed hemorrhoid, which can cause sudden, sharp pain and a firm purple lump. Many people have mixed hemorrhoids, meaning internal and external tissue are both involved at once.

Internal hemorrhoids are also described by grade, which reflects how much they prolapse. Grading matters because it often decides whether simple home care is enough or whether an office procedure will help.

GraadWat het betekent
Grade IBulge slightly but do not prolapse; may bleed
Grade IIProlapse when straining but slide back on their own
Grade IIIProlapse and must be pushed back in by hand
Grade IVStay prolapsed and cannot be pushed back

What Causes Hemorrhoids? Common Causes and Risk Factors

Hemorrhoids form when pressure inside the anal cushions rises repeatedly, stretching the vessels and the tissue that holds them in place. Most causes trace back to that one idea: anything that increases pressure in the pelvic and anal area, day after day, makes hemorrhoids more likely.

Everyday Habits and Pressure

Straining on the toilet is the classic trigger, especially when it is driven by constipation or hard stools. Sitting for long stretches, including long stays on the toilet with a phone, keeps blood pooled in the area. A low-fiber diet, not drinking enough water, and heavy lifting all raise the same kind of pressure. Chronic diarrhea can irritate the tissue just as much as constipation.

Life Stages and Health Conditions

Pregnancy is a well-known cause, because the growing uterus presses on pelvic veins and hormones relax vessel walls; many cases appear in the third trimester or after delivery. Aging weakens the supporting tissue, so hemorrhoids become more common with each decade. Obesity and a family tendency toward weak vein walls add to the risk. By around age 50, close to half of adults have dealt with hemorrhoids at some point, according to the American College of Gastroenterology.

Symptoms and Signs of Hemorrhoids

The symptoms of hemorrhoids depend heavily on whether they are internal, external, or mixed. Recognizing the pattern helps you judge how urgent the situation is and which relief measures make sense.

Bleeding, Itching, and Discomfort

Painless, bright-red bleeding is the hallmark of internal hemorrhoids. External hemorrhoids more often bring itching, a feeling of fullness, swelling, and soreness that worsens when you sit. Some people notice mucus, skin irritation, or a soft lump they can feel near the opening. Symptoms frequently flare for a few days and then quiet down, which is why many flare-ups never reach a doctor.

Thrombosed Hemorrhoids

When a clot forms in an external hemorrhoid, the pain can arrive quickly and feel intense. A thrombosed hemorrhoid usually shows up as a hard, bluish lump that is tender to the touch. The pain often peaks within the first two or three days and then eases as the body reabsorbs the clot. Severe or worsening pain is a reason to be seen promptly, since early treatment can bring faster relief.

Diagnosis: Why Not All Rectal Bleeding Is Hemorrhoids

A hemorrhoid diagnosis usually starts with a conversation about your symptoms and a physical exam. The most important idea in this whole article is simple: bleeding from the bottom is a symptom, not a diagnosis. Hemorrhoids are the most common cause, but anal fissures, inflammation, polyps, and, less often, cancer can look similar at first. Because several conditions share the same sign, it is worth taking a moment to read our detailed guide to rectale bloeding.

How Doctors Examine Hemorrhoids

Clinicians confirm hemorrhoids by looking at the area and, for internal ones, by using a short lighted scope called an anoscope. A gloved finger exam, known as a digital rectal exam, checks for lumps and tenderness. If the bleeding pattern is unusual, or you have other risk factors, your clinician may recommend a colonoscopy, which can detect an early darmkanker long before it causes serious trouble.

Reading the Clues in Your Symptoms

The color and timing of bleeding offer clues. Bright-red blood that coats the stool or drips into the bowl points toward the anal area, while darker, tarry stool suggests bleeding higher in the digestive tract; our guide explains what causes zwarte vlekjes in de ontlasting. If inflammation is a concern, a stool test can measure fecaal calprotectine, which helps separate an irritable bowel pattern from inflammatory bowel disease.

Wanneer een arts raadplegen

Most hemorrhoid flare-ups are safe to manage at home. Still, some signs mean you should book an appointment rather than wait, mainly to rule out other causes of bleeding. See a clinician if you notice any of the following:

  • Bleeding that lasts more than a week, keeps coming back, or is heavy
  • Black, tarry, or maroon stools, which can signal bleeding higher up
  • A change in your normal bowel habits, stool caliber, or new constipation and diarrhea
  • Rectal bleeding for the first time, especially if you are over 45
  • A personal or family history of colorectal cancer, polyps, or inflammatory bowel disease
  • Bleeding with unexplained weight loss, fatigue, dizziness, or paleness
  • Severe anal pain, or a hard lump that is rapidly getting worse

Ongoing or heavy bleeding can slowly add up. Over months, small repeated losses can quietly produce iron-deficiency anemie. When bleeding is significant, your doctor may order a complete blood count test to see whether your red cells are affected, and blood work done afterward frequently reveals low ferritine, the protein that reflects your iron stores. To see the fuller picture, your clinician may also request an panel voor ijzeronderzoek.

Treatment: From Home Care to Procedures

Treatment for hemorrhoids follows a ladder. Almost everyone starts at the bottom rung with simple measures, and only a minority need procedures or surgery. The goal is to relieve symptoms and, just as importantly, to remove the pressure that caused the problem in the first place.

Home and Lifestyle Care

First-line care is the same care that prevents hemorrhoids: more fiber, more water, and no straining. A warm sitz bath, sitting in a few inches of plain warm water for ten to fifteen minutes, eases spasm and soreness. Over-the-counter creams, witch hazel pads, and short courses of medicated ointments can calm itching and swelling, though they treat symptoms rather than the cause. Gentle cleaning and avoiding long toilet sits also help the tissue recover.

Office Procedures

When internal hemorrhoids keep bleeding or prolapsing despite good home care, quick office procedures often solve the problem without surgery. Rubber band ligation is the most common: the clinician places a tiny band at the base of an internal hemorrhoid, cutting off its blood supply so it shrinks and falls away within days. Other options include sclerotherapy, where a solution is injected to collapse the vessel, and heat- or laser-based techniques. These are done in minutes, usually without anesthesia.

Surgery for Advanced Cases

A small share of hemorrhoids, usually large, prolapsing, grade III or IV cases, need surgery. Hemorrhoidectomy removes the tissue and offers the most durable results, especially for mixed disease. Newer approaches aim to reduce blood flow to the hemorrhoids or lift prolapsed tissue with fewer days of recovery. A colorectal surgeon can match the method to your anatomy, your symptoms, and your overall health.

Preventing Hemorrhoids

Prevention is largely about protecting your bowel habits. Aim for 25 to 35 grams of fiber a day from vegetables, fruit, legumes, and whole grains, and increase it gradually to avoid gas. Drink enough water so stools stay soft. Answer the urge to go promptly instead of holding it, and keep toilet visits short. Regular movement, from walking to structured exercise, keeps the digestive system active and lowers pressure in the pelvic veins.

Because straining is the common thread, managing constipation is prevention that pays off. A quick reference like the Bristol chart can help you track your stool consistency and catch trouble early. If constipation is stubborn, a fiber supplement or a stool softener, chosen with your pharmacist or doctor, can break the cycle before hemorrhoids return.

Recente wetenschappelijke ontwikkelingen

Hemorrhoid research over the past three years has focused less on dramatic new cures and more on getting the basics right: accurate diagnosis, matching treatment to the individual, and knowing when bleeding needs deeper evaluation. Here is what recent work adds, in plain terms.

A 2025 review in JAMA underlined just how common the problem is, estimating that hemorrhoidal disease affects roughly 10 million people in the United States, and reaffirmed the internal, external, and mixed classification that steers treatment. What this means for you: your hemorrhoid type and symptoms, not a single default remedy, should guide the plan you and your clinician choose.

Two recent surgical reviews reinforced a “least invasive first” approach. A 2025 review concluded that good care starts by fixing modifiable risk factors, such as straining and low fiber, before moving to procedures, while a 2023 review highlighted that even specialists correctly identify benign anorectal problems only about seven times in ten. What this means for you: lifestyle steps genuinely come first and often work, and a proper exam matters more than self-diagnosis, because look-alike conditions are easy to confuse.

Prevention science has firmed up too. In 2024, the American Society of Colon and Rectal Surgeons issued updated guidance on managing chronic constipation, the main driver of straining. What this means for you: treating constipation with fiber, fluids, and steady bowel habits is not just folk advice; it is backed by current specialty guidance, and it protects against repeat flare-ups.

Finally, researchers keep sounding the same careful note about bleeding. A 2023 study found that rectal bleeding is among the most common first symptoms of colorectal cancer in adults under 50, a group whose case numbers have been rising. What this means for you: do not assume that being young rules out a serious cause, and treat new or persistent bleeding as a reason to be checked, even when hemorrhoids are the likely answer.

veelgestelde vragen

What do hemorrhoids look like?

It depends on the type. External hemorrhoids can look like soft or firm bumps around the anal opening, sometimes bluish if a clot has formed. Internal hemorrhoids usually cannot be seen from the outside unless they prolapse, in which case they appear as moist pink tissue bulging from the anus. Many people never see their hemorrhoids at all and only notice bright-red blood on the toilet paper or a feeling of fullness. If a lump is hard, rapidly growing, or bleeding heavily, have it examined rather than trying to identify it yourself.

How do you get rid of hemorrhoids at home?

Most flare-ups improve within a week or two with simple steps: eat more fiber, drink more water, and avoid straining or long toilet sits. Warm sitz baths several times a day ease soreness, and over-the-counter creams or witch hazel pads can calm itching and swelling. Cold packs help a painful external lump. These measures relieve symptoms and give irritated tissue time to heal, but they work best when you also fix the underlying cause, which is usually constipation and straining.

Do sitz baths really help hemorrhoids?

Yes, for comfort. A sitz bath, sitting in a few inches of plain warm water for ten to fifteen minutes, relaxes the anal muscles, improves blood flow, and soothes itching and pain. It is one of the most recommended home measures and is especially helpful after a bowel movement or for a tender external hemorrhoid. A sitz bath will not shrink a large or prolapsing internal hemorrhoid, but it makes the day-to-day discomfort far more manageable while other measures take effect.

Does eating more fiber help with hemorrhoids?

Fiber is one of the most effective tools available. By softening and bulking the stool, fiber reduces the straining that drives hemorrhoids, which eases both bleeding and discomfort over time. Aim for 25 to 35 grams a day from food, and add it gradually with plenty of water to avoid bloating. If diet alone is not enough, a fiber supplement can help. This is prevention and treatment at the same time, which is why clinicians almost always start here.

When is hemorrhoid bleeding serious?

Occasional bright-red spotting from a known hemorrhoid is usually not an emergency. Bleeding becomes a concern when it is heavy, lasts more than a week, keeps returning, or comes with dark or tarry stools, a change in bowel habits, weight loss, or fatigue. First-time bleeding after age 45 should always be evaluated. These features do not mean you have something serious, but they are the situations where a doctor should confirm the cause instead of assuming hemorrhoids.

Can hemorrhoids go away on their own, and do they come back?

Mild hemorrhoids often settle on their own within days once straining stops, and many people have occasional flare-ups that resolve without treatment. However, hemorrhoids can return whenever the pressure that caused them returns, so lasting relief depends on steady habits: fiber, fluids, activity, and not straining. Larger or higher-grade hemorrhoids are less likely to disappear completely and may need an office procedure, but even then, good bowel habits reduce the chance of recurrence.
