Epistaxis

DE FR EN

Almost always from a small vessel at the front of the nose — pressed correctly it usually stops quickly.

A nosebleed often looks more dramatic than it is — in the vast majority of cases it’s harmless. The bleeding usually comes from a well-supplied network of vessels at the front of the septum that is easily hurt: dry heated air, nose-blowing or picking, a small knock or blood-thinning medicines are often enough. With the right move it can nearly always be stopped quickly: sit upright, head slightly forward, and firmly pinch the soft part of the nose for 10 to 15 minutes without letting go. Importantly, don’t tip the head back. For heavy, unstoppable or repeatedly recurring bleeds, a medical check is worthwhile.

Levers & pathways

associatedFirst aid, done right

Sit upright, head slightly forward, firmly pinch the soft part for 10-15 min.

associatedDon’t tip the head back

Otherwise blood runs into the throat — a cold pack on the neck can also help.

associatedCare for the lining

After it stops, avoid hard blowing for a few days; humid air and nasal care prevent recurrence.

associatedWhen to see a doctor

If unstoppable, very heavy, recurrent or on blood thinners.

traditionalStopping a nosebleed properly

Sit upright, tilt the head slightly forward, pinch the soft part of the nose firmly for 10 to 15 minutes without letting go.

infoNumbers and timeframes

Nine out of ten nosebleeds come from a network of vessels at the front of the septum and can be stopped from outside: press the soft part of the nose together for ten to fifteen minutes without letting go, head forward. Letting go to look is the most common reason a nosebleed does not stop. Bleeds further back are rarer, affect older people more, and rarely stop by themselves.

infoWhat the medicine does — and what it does not

Decongestant nose drops on a swab tighten the vessels and help with fresh bleeding — dry cotton wool pushed in tears the crust open again when removed. Ointments with dexpanthenol or nasal oil keep the lining moist over weeks and lower recurrence; that is the part that really changes something. Tipping the head back does not help: the blood then runs into the throat and stomach and causes nausea.

Possible complaints

associatedUsually harmless, at the front

Almost always comes from the front, well-supplied part of the septum.

associatedCommon triggers

Dry air, nose-blowing/picking, small knock, blood thinners, high blood pressure.

associated⚠️ Won’t stop / after injury

Bleeding not stopping after 20-30 min, very heavy or after a fall → doctor/emergency.

associatedRecurrent: get checked

Frequent nosebleeds without a clear cause are worth a calm medical look.

Blood values

associatedPlatelets

Only for frequent/heavy nosebleeds — usually no blood test is needed.

Nutrients

studiedFluid and air humidity

The most common cause of all is a dried-out lining — heated air in winter, drinking too little, nose sprays. A moist nose bleeds far less often.

associatedVitamin C

Needed for stable vessel walls. A marked lack causes bleeding from gums and skin; it is rare today but occurs with a very one-sided diet and alcohol.

associatedVitamin K

Needed for clotting. A lack arises with disturbed fat uptake, after long antibiotic treatment and with liver disease — and under coumarins it is intended and measured.

studiedIron

After the bleeding, not before: frequent or heavy nosebleeds empty the iron store. With repeated episodes ferritin belongs with it.

Supplements

infoOmega-3 (EPA/DHA)

From about 3 g EPA+DHA a day the bleeding time lengthens measurably. Together with blood thinners or painkillers, that is where repeated nosebleeds get an explanation.

infoGinkgo biloba

Among the plant remedies that can influence clotting — as can garlic and high-dose vitamin E. Anyone bleeding regularly goes through their own list before treating the nose.

no studiesVitamin C

With scurvy the small vessels break — that link is old and correct. Without a deficiency no benefit against nosebleeds is shown; dry indoor heating in winter explains far more cases.

infoIron

Clearly effective with proven deficiency, useless without. Take only with a documented deficiency — excess is harmful.

Hormones

studiedEstradiol

In pregnancy the lining of the nose swells and gets a richer blood supply — nosebleeds and a blocked nose without a cold are therefore common and harmless. Both go after the birth.

infoAdrenaline

Decongestant nasal sprays work through the same route that narrows the vessels. Beyond a week that reverses: the lining swells more than before, and it bleeds more easily.

Food

associatedWhat also affects clotting

High amounts of fish oil, ginkgo and garlic as supplements slightly lengthen bleeding time. With frequent nosebleeds the supplement list is worth a look — in culinary amounts it is not an issue.

Alternative approaches — what people use

no studiesVitamin C

Recommended for fragile vessels; proof is missing for nosebleeds. Moisture in the nose works better — dry heated air is the most common cause in winter.
