Why do hemorrhoids bleed, and what actually stops it?

In adults with internal or external hemorrhoids presenting with rectal bleeding, what is the underlying cause of the bleeding, and which treatments (dietary/fiber measures, topical agents, office-based procedures such as rubber band ligation or sclerotherapy, or surgery) most effectively stop or reduce hemorrhoidal bleeding?

How people search for this, in their own words

What the evidence says

Bottom line

Several office procedures and medicines have been shown in trials to reduce or stop hemorrhoid bleeding — but no study in this review actually explains why hemorrhoids bleed in the first place.

The strongest evidence comes from five well-conducted randomised trials comparing one bleeding-control option against another — banding, injection sclerotherapy, and artery-blocking procedures — and most show real improvement in bleeding. Almost none of the studies compared a treatment with doing nothing, so they answer 'which treatment works better' rather than 'does treatment help at all.' The basic biology of why hemorrhoids bleed was not tested in people in any of these studies.

What the research shows

  • Cessation of rectal bleeding

    Rubber band ligation, sclerotherapy injections, and artery-blocking procedures stopped or markedly reduced bleeding in most people treated across multiple studies, including randomised comparisons.[1,2,3,4,5,6,7,8]

    Improvement shown

  • Time to resolution of bleeding

    Some studies suggest bleeding can ease within one to four weeks, or after one or two treatment sessions, but this wasn't measured consistently as a formal time-to-event outcome across controlled trials.[1,2,3]

    Possible improvement

  • Recurrence of bleeding at follow-up

    Treatments reduced bleeding initially, but recurrence was common on longer follow-up — ranging from about 12% to over 30% within one to five years depending on the study and technique.[1,2,3,4,5]

    Possible improvement

  • Need for further procedural or surgical intervention

    Some techniques lowered the chance of needing a repeat procedure compared with others, but a meaningful minority of patients across studies still needed further treatment or surgery.[1,2,3]

    Possible improvement

  • Change in hemoglobin or anemia status

    Only a couple of small studies looked at blood counts, mostly in patients with severe bleeding needing transfusion or with liver disease; this wasn't a standard outcome in the treatment trials.[1,2]

    Insufficient evidence

  • Patient-reported symptom severity score

    Across many studies, overall symptom scores (including bleeding, pain, swelling and quality of life) dropped significantly after treatment.[1,2,3,4,5,6,7]

    Improvement shown

  • Underlying biological cause of bleeding

    No study in this review tested, in humans, why hemorrhoids bleed. The only mechanism-focused work was done in rats and lab tissue samples, which doesn't reliably show what happens in people.

    Not studied

What it may help with

  • Rubber-band ligation and sclerotherapy (an injection that scars and shrinks the hemorrhoid) stopped or markedly reduced bleeding in multiple trials and cohort studies, including head-to-head comparisons against each other and against surgery.[1,2,3,4,5,6,7,8]
  • Oral vein-supporting medicines (flavonoids, including micronized purified flavonoid fraction) reduced bleeding scores compared with placebo or routine care in several trials.[1,2,3,4,5,6]
  • Procedures that block the artery feeding the hemorrhoid (embolization) reduced bleeding scores in multiple cohort studies and a small randomised trial.[1,2,3,4,5,6,7]
  • Surgery to remove hemorrhoids controlled bleeding well in people with more severe disease, and a large comparison across many trials found it gave the lowest recurrence among procedural options.[1,2]

Important limitations

  • Most studies compared one active treatment with another, not treatment against doing nothing, so how much benefit comes from the treatment itself versus natural improvement over time is often unclear.[1,2,3,4]
  • Many studies were retrospective or single-arm with no comparison group, meaning people could have partly improved on their own rather than because of the treatment.[1,2,3,4,5,6]
  • Follow-up was often short. In studies that did look further out, bleeding and other symptoms frequently returned, sometimes in a quarter or more of patients.[1,2,3,4]
  • None of these studies explain, in humans, the underlying biology of why hemorrhoids bleed. The only mechanism research was done in rats and lab tissue, which doesn't necessarily reflect what happens in people.[1,2,3]

    size not given2023

    Fiber, stool softeners and mild laxatives are considered safe; topical medication and oral phlebotonics need caution due to lack of safety/efficacy evidence; anal packing can help with massive bleeding; surgery reserved for severe cases

    Who was studied
    pregnant women with hemorrhoids
    What they received
    various hemorrhoid treatments (fiber, stool softeners, laxatives, topical medication, phlebotonics, anal packing, hemorrhoidectomy)
    Compared with
    no formal comparator; narrative synthesis of treatment options
    Main outcome
    safe and effective management of hemorrhoids in pregnancy, including bleeding control
    Quality
    This is a non-systematic literature review without pooled data, numbers of patients, or quality assessment of included studies.
    Limitations
    No language selection or systematic methodology described, no participant numbers given, and abstract notes lack of strong evidence for several treatments in pregnancy.

    Taken word for word from the abstract

    • population Inflammatory Bowel Diseases (IBD), pregnancy, immunosuppression, coagulopathy, cirrhosis with portal hypertension, and proctitis after radiotherapy, challenge hemorrhoids management and the outcomes
    • intervention The first-line treatment is the conservative medical approach associated with the treatment of the primary disease.
    • comparator Patients in pregnancy can be effectively treated with medical therapy, reserving surgical intervention in highly selected and urgent cases.
    • primaryOutcome There are very limited data about the outcomes of hemorrhoids treatment in these subgroups of patients.
    • result Bleeding hemorrhoids can be treated with hemorrhoidectomy when they do not respond to other treatments.
    • result In case of portal hypertension and cirrhosis, a 'conservative treatment' is recommended.
    • qualityWhy International literature is very scant about the treatment of patients affected by hemorrhoids in particular situations.

Risks and safetyReported side effects and who should be careful.
  • Rubber band ligation can rarely cause serious delayed bleeding, even needing emergency treatment, days after the procedure.
  • People taking blood-thinning medication had higher rates of bleeding complications after hemorrhoid procedures, though severe bleeding needing hospital admission was not more common.
  • Surgical removal of hemorrhoids caused more pain, bleeding and urinary retention than less invasive office procedures in a large comparison across many trials.
Why people try thisThe reasoning behind the question — not a claim that it works.
  • Seeing blood in the toilet or on tissue is frightening, so people want it to stop right away.
  • Surgery sounds painful and inconvenient, so many look for creams, diet changes, or in-office treatments first.
  • Hemorrhoid creams and suppositories are sold over the counter and heavily marketed as a quick fix.
  • Some people hope diet and fiber alone will solve it without having to see a doctor about a sensitive problem.
Common questionsShort answers, drawn from the same studies.
Why is my hemorrhoid bleeding?
Hemorrhoids are swollen blood vessels in and around the anus, and their surface can wear thin or tear, especially as stool passes over them. The studies in this review test ways to stop that bleeding rather than explain the biology behind it, so the exact mechanism wasn't directly studied here.
Can internal hemorrhoids bleed?
Yes. Many of the studies in this review specifically treated internal hemorrhoids where bleeding was the main symptom, including grade I through grade IV disease, and measured whether that bleeding stopped after treatment.
How long do internal hemorrhoids bleed?
This varies and isn't firmly pinned down by the evidence. In one trial, injection sclerotherapy stopped bleeding in about 6 in 10 people after one session and about 9 in 10 after a second session within a few months; other studies saw improvement within one to four weeks of starting treatment. Ongoing bleeding should be checked by a doctor rather than waited out.
How do I stop internal hemorrhoids from bleeding?
In these studies, office-based treatments such as rubber band ligation and sclerotherapy injections stopped or reduced bleeding in most people treated, and oral vein-supporting medicines (flavonoids) also reduced bleeding compared with placebo or routine care. Surgery was used for more severe cases and controlled bleeding well, but came with more pain and its own bleeding risk.
When should I see a doctor about hemorrhoid bleeding?
Rectal bleeding can come from causes other than hemorrhoids, so it's worth getting checked, especially if it's heavy, persistent, painful, or you're over 45 or feel dizzy or unusually tired. The studies here only looked at people whose bleeding had already been confirmed to be from hemorrhoids.

This is information, not advice

This page summarises published research. It cannot tell you what is happening in your own body, and evidence changes. If something is bleeding, painful, or new, it is worth being looked at — that is a different question from the one on this page, and a better one to bring to a consultation.
