Overview
Nosebleeds are common and are usually not serious. Most start near the front of the nose and stop with simple first aid at home.
How common is it?
Most people will have a nosebleed at some point. They are especially common in children and older adults.
Causes and risk factors
Common causes include nose picking, forceful nose blowing, dry air, colds, and minor knocks to the nose. Recurrent or heavy nosebleeds can be harder to stop if you take blood-thinning medicine or have a clotting problem.
Common risk factors
- Dry air or heated indoor air
- Colds, allergies, or irritated nasal lining
- Nose picking or forceful nose blowing
- A knock to the nose
- Blood-thinning medicines
- Conditions that affect blood clotting
Symptoms
- Bleeding from one or both nostrils
- Blood running into the throat if the bleeding goes backwards
- Feeling light-headed if the bleed is heavy
When to see a doctor
Get urgent help if bleeding lasts more than 10 to 15 minutes despite firm pressure, seems very heavy, follows a blow to the head, or makes you feel weak, dizzy, short of breath, or sick from swallowing blood. See a GP if you get repeated nosebleeds, take blood thinners, or a child under 2 has a nosebleed.
Diagnosis
Most nosebleeds do not need tests. Recurrent or severe nosebleeds may need an examination of the nose, a blood pressure check, or blood tests.
Treatments
First aid
Sit down, lean forward, and pinch the soft part of the nose for 10 to 15 minutes without checking too early. Breathe through your mouth and do not tilt your head back.
Medical treatment
If the bleeding point is visible or the bleed will not stop, a clinician may use cautery or pack the nose.
Aftercare and prevention
For the rest of the day avoid heavy exercise, hot drinks, blowing your nose, or picking at the inside of the nose while it heals.
Self-care and lifestyle
- Use saline spray or a humidifier if the inside of the nose is dry
- Keep fingernails short for children who pick their nose
- Follow advice about blood thinners if bleeds are happening often
- Avoid smoking if it irritates your nose
Prevention
Keeping the nose moist and avoiding picking, forceful blowing, and dry air can reduce repeat nosebleeds.
