Hemorrhoid symptoms are among the most common reasons adults quietly search for a health answer, and the answer is usually reassuring: swollen vascular cushions inside the anal canal or under the skin at the anal opening, irritated by pressure and straining. What matters far more than the label is the sign people are quickest to explain away: bleeding. Blood on the paper is very often hemorrhoidal, but it can also come from an anal fissure, an inflamed bowel, diverticular disease or a colorectal tumor, and nobody can tell which by looking. In this article you will learn how internal and external hemorrhoids differ, how doctors grade them, which treatments work at each stage, which warning signs deserve an examination, and where blood and stool tests genuinely help.
What hemorrhoids are, and why nearly everyone has them
Hemorrhoids are not an abnormality appearing out of nowhere. Everyone is born with three cushions of blood vessels, connective tissue and smooth muscle just inside the anal canal, which help seal the anus and give fine control over gas and stool. They become a problem only when repeated pressure stretches the tissue anchoring them, so the cushions engorge, slip down, bleed or clot.
That distinction explains a lot. You cannot remove the anatomy, because it is normal and useful; you can only lower the pressure that makes it symptomatic and treat the cushions already damaged.
Internal hemorrhoids
Internal hemorrhoids sit above the dentate line, the boundary inside the anal canal where sensitive skin gives way to bowel lining. That lining has very few pain fibers, which is why internal hemorrhoids classically bleed without hurting. People describe bright red blood streaking the stool or appearing on the paper, with no pain at all. Larger ones may bulge during a bowel movement, produce a feeling of incomplete emptying, or leak mucus that irritates the skin.
External hemorrhoids
External hemorrhoids form below the dentate line, under skin richly supplied with nerves. These are the painful ones: itching, burning, a tender lump at the anal margin and difficulty cleaning the area. They bleed less often than internal hemorrhoids, and usually leave only a trace of bright red on the paper.
Thrombosed and prolapsed hemorrhoids
Two complications account for most emergency visits. A thrombosed external hemorrhoid forms when blood clots inside the swollen vein, creating a firm, purplish, exquisitely painful lump over a few hours. A prolapsed internal hemorrhoid has slipped through the anal opening; it may retract, need pushing back, or stay out. If its blood supply is pinched off it is called strangulated, which is urgent.
The grading system doctors use
Internal hemorrhoids are graded from one to four, and the grade drives treatment more than the symptoms do. That is why a clinician usually wants to look before recommending anything beyond home care.
| Grade | What is happening | Usual first-line approach |
|---|---|---|
| Grade 1 | Bulge into the canal and may bleed, but never come outside | Fiber, fluids, toilet habits, brief topical treatment |
| Grade 2 | Prolapse during a bowel movement, then slide back unaided | Conservative care, then an office procedure if bleeding persists |
| Grade 3 | Prolapse and stay out until pushed back by hand | Office procedure such as banding; surgery if that fails |
| Grade 4 | Permanently outside and cannot be pushed back | Surgical assessment, especially with pain, clotting or soiling |
Hemorrhoid symptoms, and what each one usually means
Symptoms cluster in predictable ways, and the pattern tells a clinician more than any single complaint.
- Painless bright red bleeding at the end of a bowel movement points to internal hemorrhoids, but it is also how several other conditions present.
- Sharp, tearing pain during defecation that lingers afterward suggests an anal fissure.
- A sudden, hard, extremely tender lump suggests a thrombosed external hemorrhoid.
- Itching, moisture and skin irritation usually come from mucus leakage or a prolapsing cushion that prevents proper sealing.
- A dragging sensation, or a feeling of incomplete emptying, often accompanies grade 2 and grade 3 prolapse.
- Fatigue, breathlessness on stairs or unusual paleness are not hemorrhoid symptoms; they suggest blood loss has gone on long enough to lower your red cell count.
Symptoms are broadly identical in women and men, though pregnancy and delivery make flare-ups far more frequent. Constipation from iron supplements or certain pain medications is another common trigger.
Rectal bleeding is a symptom, not a diagnosis
This is the part of the topic that deserves the most attention. Hemorrhoids are so common that they become the default explanation, and they frequently coexist with something else. Finding hemorrhoids on examination does not prove they caused the bleeding. Mayo Clinic puts it plainly in its guidance on hemorrhoid symptoms and causes: do not assume rectal bleeding is from hemorrhoids, especially when bowel habits or stool appearance have changed.
What else causes blood in the stool
Several conditions produce bleeding that looks identical.
- An anal fissure, a small tear in the anal lining, causes bright red blood with intense pain during and after a bowel movement.
- Diverticular disease can bleed briskly and painlessly, typically in older adults, sometimes a large volume of dark red blood at once.
- Inflammatory bowel disease causes bleeding mixed with mucus, diarrhea, urgency and abdominal pain. Our library explains Crohn’s disease symptoms and treatments and describes ulcerative colitis symptoms and treatments.
- Colorectal polyps and tumors may bleed intermittently, often painlessly, with blood mixed into the stool rather than sitting on its surface. We cover colorectal cancer symptoms, screening and treatment separately.
- Bleeding higher in the digestive tract produces black, tarry stool rather than red blood. Our marker guide describes visible blood in stool and how its appearance narrows the possible sources.
Red flags that call for an examination, not a cream
Any of the following is worth an appointment rather than self-treatment, even when hemorrhoids are known to be present.
- You are 45 or older and this is new bleeding, or you are younger with persistent bleeding that has no obvious explanation.
- Your bowel habit has changed for several weeks: looser or narrower stools, new constipation, or alternating patterns.
- You are losing weight without trying, or your appetite has dropped.
- The blood is dark, maroon or mixed through the stool rather than bright red on its surface.
- A parent, sibling or child had colorectal cancer or advanced polyps, or you have inflammatory bowel disease.
- You feel unusually tired, breathless, dizzy or pale, which can indicate anemia from ongoing blood loss.
- Bleeding is heavy, comes with fever or severe abdominal pain, or with a painful lump that keeps growing.
None of these signs means cancer. They mean the bleeding is not yet explained, and only an examination can explain it.
What causes hemorrhoids and who is most at risk
The mechanism is mechanical: anything that repeatedly raises pressure inside the abdomen and the anal canal stretches the tissue holding the cushions in place.
Chronic constipation and straining top the list, followed by long periods on the toilet, often with a phone in hand. Chronic diarrhea irritates the area just as effectively. Pregnancy combines hormonal relaxation of vein walls with pressure from the uterus, and delivery adds acute strain. Obesity, heavy lifting, prolonged sitting and a low-fiber diet all contribute, and risk rises with age as supporting tissue weakens, which is why grade 3 and grade 4 hemorrhoids are commoner after 50. Cold surfaces, spicy food and coffee are often blamed but have not been shown to cause them.
How hemorrhoids are diagnosed, and where lab tests fit
Diagnosis starts with the history and a physical examination, including a digital rectal exam and usually anoscopy, a short lighted tube that shows the anal canal directly. External hemorrhoids and fissures are visible on inspection; internal ones are graded during the same examination.
Anyone with red flags, or whose bleeding does not fit a simple hemorrhoidal pattern, needs the colon itself examined, usually by colonoscopy. Laboratory tests do not replace that, but they answer two questions: how much blood has been lost, and whether anything points beyond the anal canal.
Blood tests: how much blood has been lost
Hemorrhoids rarely bleed dramatically, but slow, repeated loss adds up. Doctors usually order a complete blood count first. It reports your hemoglobin level and the size of your red cells, and small, pale cells are the classic footprint of iron deficiency. Because iron stores empty long before hemoglobin falls, clinicians also check your ferritin level, the protein that reflects stored iron. Low ferritin alongside months of rectal bleeding shows the loss has been real and sustained, and prolonged loss can produce iron deficiency anemia.
One caution matters: ferritin also rises with inflammation or infection, so a normal value in someone unwell does not reliably exclude depleted iron stores. Doctors read it alongside the blood count and the clinical picture.
Stool tests: what they can and cannot settle
The fecal occult blood test, and its modern version the fecal immunochemical test, detects hemoglobin in stool invisible to the eye. It was designed to screen people with no symptoms at all. In someone already bleeding visibly, a positive result adds almost nothing, because the hemorrhoid itself makes it positive. Our guide to the fecal occult blood test explains how the two versions differ. Where inflammatory bowel disease is possible, clinicians may add a fecal calprotectin test, which measures inflammation in the bowel lining.
| Test | What it can show | What it cannot do |
|---|---|---|
| Complete blood count | Whether blood loss has lowered hemoglobin and shrunk red cells | Locate where the bleeding comes from |
| Ferritin | Whether iron stores are depleted, often before anemia appears | Stay reliable during inflammation or infection |
| Fecal occult blood or FIT | Hidden blood in stool, mainly for screening people without symptoms | Tell hemorrhoid blood from tumor blood, or replace colonoscopy |
| Fecal calprotectin | Inflammation of the bowel lining, typically raised in bowel disease | Detect cancer, or diagnose hemorrhoids |
Treatment, from home care to surgery
Conservative management, which resolves most cases
Grade 1 and many grade 2 hemorrhoids settle with unglamorous measures applied consistently for several weeks. Raise dietary fiber gradually toward 25 to 35 grams a day, drink enough that stools stay soft, and add psyllium if diet is not enough. Stop straining and stop reading on the toilet; time spent sitting and pushing is the most modifiable factor. Warm sitz baths of ten to fifteen minutes relax the sphincter and relieve pain. Topical products calm itching, but steroid creams should not be used beyond a week because they thin the skin.
Office procedures
When bleeding continues despite good conservative care, or prolapse becomes a nuisance, the next step is an office procedure done without general anesthesia.
- Rubber band ligation is the most widely used. A tiny elastic band placed at the base of an internal hemorrhoid cuts off its blood supply, and the tissue shrinks and falls away within one to two weeks. It works only above the dentate line, and often takes two or three sessions.
- Sclerotherapy injects a solution that scars and shrinks the hemorrhoid. It is gentler and often preferred for people on blood thinners.
- Infrared coagulation uses heat to seal small vessels, mainly in grade 1 and grade 2 disease.
Bleeding, a dull ache and pressure for a few days are expected after banding. Severe pain, fever or difficulty passing urine are not, and warrant a call.
When surgery is considered
Surgery is reserved for grade 3 and grade 4 hemorrhoids, large external components, repeated failure of office procedures, and complications such as strangulation. Conventional hemorrhoidectomy removes the tissue and is the most durable option, at the cost of an uncomfortable two to three week recovery. Stapled hemorrhoidopexy lifts prolapsed tissue back into place and transanal hemorrhoidal dearterialization ties off the feeding arteries; both hurt less but recur more often. A clotted external hemorrhoid seen within about three days can be relieved under local anesthetic.
Preventing flare-ups and living with hemorrhoids
Prevention and treatment are the same habits: keep stools soft, respond to the urge promptly, limit toilet time to a couple of minutes, stay active, and avoid bearing down when lifting. Pregnant readers can safely use fiber, fluids, sitz baths and side-lying rest, and should ask before using a topical product.
Recurrence is common and is not a failure; the cushions are still there, and pressure finds them again during a constipated week or a long flight. What should never become routine is unexplained bleeding.
Latest scientific advances
Research over the past three years has refined two things: how aggressively to treat hemorrhoids, and how carefully to read a stool test in someone who is bleeding.
A 2025 review pooling seven studies compared surgery with non-invasive care. Surgery cleared symptoms more completely and recurred less, while conservative treatment was gentler and caused fewer procedure-related problems but worked more slowly. What this means for you: starting with fiber, fluids and habit changes remains reasonable, and moving to a procedure if symptoms persist is a legitimate choice, not a last resort.
A 2025 meta-analysis, a study that statistically combines earlier studies, looked at thrombosed external hemorrhoids. Removing the clot surgically was followed by fewer recurrences than waiting it out, with no meaningful difference in bleeding afterward. What this means for you: if a sudden painful anal lump appears, being seen early widens your options.
Surgical technique is also evolving. A 2024 pooled analysis of seventeen trials found that laser hemorrhoidoplasty, which shrinks the hemorrhoid with a fine laser fiber instead of cutting it out, involved less blood loss, shorter operations and markedly less pain on the first day, although recurrence was similar. What this means for you: if surgery is on the table, ask how early comfort trades off against long-term durability.
A 2025 systematic review examined embolization of the arteries feeding internal hemorrhoids, a catheter-based technique done by an interventional radiologist. Across twenty-two small studies it was technically reliable and controlled bleeding in most patients, with only mild, short-lived side effects, but there are almost no direct comparisons with banding or surgery. What this means for you: a promising option, especially for frail patients or people on blood thinners, but still preliminary.
A 2025 study of more than thirty-eight thousand symptomatic adults under 50 in England assessed the fecal immunochemical test, the stool test that detects hidden blood. It performed strongly in people in their forties and less dependably under 40, where a positive result far more often reflected something benign. What this means for you: it is a triage tool that helps decide who needs a camera test sooner, not a verdict in either direction.
A five-year audit published in 2024 reinforced that caution. Among people later diagnosed with colorectal cancer who had been tested in the preceding year, roughly one in twelve had a negative stool blood test, and the commonest reasons for ordering it were a change in bowel habit, then iron deficiency anemia. What this means for you: a reassuring stool test does not cancel out persistent symptoms, and unexplained iron deficiency needs an explanation of its own.

Frequently asked questions
Do hemorrhoids go away on their own?
Mild flare-ups often do. Symptoms from grade 1 and grade 2 hemorrhoids commonly settle within a few days to two weeks once straining stops and stools become softer. A thrombosed external hemorrhoid usually becomes less painful after three or four days and gradually shrinks over two to three weeks, sometimes leaving a small skin tag behind. What does not disappear is the underlying tendency, so symptoms can return whenever constipation, pregnancy or long toilet sessions come back. Bleeding that lasts beyond a week, or that keeps returning, should be assessed rather than waited out.
Can you get rid of external hemorrhoids in 48 hours?
No treatment reliably clears an external hemorrhoid in two days, and claims of a two-day or three-day cure are not supported. What can change quickly is comfort. Sitz baths, cold packs applied briefly, a stool softener and stopping straining often reduce pain noticeably within 24 to 48 hours. The one situation where rapid relief is genuinely possible is a very painful clotted hemorrhoid seen by a clinician within about three days, when removing the clot under local anesthetic can relieve the pain almost immediately.
Are hemorrhoid symptoms different in women?
The symptoms themselves are the same, but the triggers differ. Pregnancy and childbirth make hemorrhoids far more common, because hormones relax vein walls, the growing uterus increases pressure, and pushing during delivery adds acute strain. Postpartum constipation and iron supplements prolong the problem. Women also more often attribute bleeding to hemorrhoids after delivery when a fissure is responsible. Any bleeding that persists after the postpartum period, or that comes with a changed bowel habit, deserves the same evaluation it would receive in anyone else.
Are hemorrhoids dangerous?
Hemorrhoids themselves are not dangerous in the sense of threatening life, and they do not turn into cancer. The two real risks are indirect. First, ongoing blood loss can slowly cause iron deficiency and anemia, which is easy to miss because it develops gradually. Second, and more important, assuming that hemorrhoids explain every episode of bleeding can delay the diagnosis of a condition that needed attention sooner. Complications such as strangulation or a large clot are painful and need prompt care, but they are uncommon.
Can hemorrhoids cause anemia?
Yes, though it is not the usual outcome. Most hemorrhoidal bleeding is small in volume and intermittent, and the body replaces it easily. When bleeding is heavier or continues for months, iron stores fall first and the red cell count follows. Warning signs include fatigue out of proportion to your activity, breathlessness climbing stairs, palpitations, pale skin or unusual craving for ice. If those appear, a blood count and a ferritin measurement will show whether iron has been depleted, and your clinician will want to confirm that hemorrhoids are truly the source.
Is it normal for hemorrhoids to come back?
It is common. The anal cushions are permanent anatomical structures, so treatment relieves the current problem rather than removing the tendency. Recurrence rates are lowest after conventional surgery and higher after office procedures, which is part of the trade-off against a much easier recovery. Sustained habits make the biggest difference: adequate fiber and fluid, short toilet visits, prompt response to the urge, and regular activity. Recurrent bleeding that follows a familiar pattern is usually the hemorrhoids again, but a change in that pattern should be checked.
