Frequent bloody noses are usually caused by irritation or dryness in the front part of the nose, but they can sometimes be a sign of an underlying medical problem and should be checked by a doctor if they keep happening.

Quick Scoop

“Why do I keep getting bloody noses?”
Think of the inside of your nose like delicate skin covered in tiny, shallow blood vessels. When anything dries, scratches, or inflames that area, it can bleed easily.

Common everyday causes

These are the most frequent reasons someone keeps getting bloody noses:

  • Dry air (winter heating, air conditioning, living in a dry climate) dries the nasal lining and makes it crack and bleed.
  • Colds, sinus infections, or allergies cause inflammation, sneezing, and a runny nose, which irritate the blood vessels.
  • Nose picking or blowing your nose really hard repeatedly directly injures the fragile vessels near the front of the septum.
  • Irritants in the air (smoke, strong chemicals) can inflame the lining and make it bleed more easily.
  • Minor trauma (getting bumped in the nose, sports hits) can lead to repeated bleeds while things are healing.
  • Some nasal sprays (especially if overused), decongestants, or antihistamines can dry or irritate the lining and trigger more frequent bleeding.

When it might be something more serious

Most nosebleeds are not dangerous, but frequent or heavy ones can sometimes be a sign of another issue:

  • Blood‑thinning medicines (like warfarin, heparin, some antiplatelet drugs) or regular aspirin use can make bleeding easier and harder to stop.
  • Bleeding or clotting disorders (such as hemophilia, von Willebrand disease, low platelets) can show up as frequent nosebleeds, easy bruising, or long bleeding from small cuts.
  • Structural issues in the nose (deviated septum, nasal deformity, polyps, or tumors) can make one area more prone to bleeding.
  • Rare conditions where blood vessels are abnormal (like hereditary hemorrhagic telangiectasia/Osler‑Weber‑Rendu) can cause recurrent nosebleeds plus visible small red spots on the skin or in the mouth.
  • Leukemia and some other cancers can sometimes first show up as frequent nosebleeds along with fatigue, infections, or lots of bruises.

If your nosebleeds are new, more frequent, heavier, or you have other symptoms (fatigue, weight loss, easy bruising, gum bleeding), that is a strong reason to get checked urgently.

What you can do right now

This is not a substitute for medical care, but these general steps are often recommended to reduce how often bloody noses happen:

  • Keep the inside of your nose moist with saline spray or saline gel several times a day, especially in winter or in air‑conditioned rooms.
  • Use a cool‑mist humidifier in your bedroom at night to reduce dryness in the air.
  • Avoid picking your nose, and try to blow gently instead of forcefully.
  • If you get a nosebleed, sit up, lean slightly forward, and pinch the soft part of your nose (not the bony bridge) firmly for about 10–15 minutes without checking too often.
  • Avoid aspirin or other over‑the‑counter pain relievers that affect clotting unless a doctor has told you to take them, and never stop prescribed medicines without talking to your clinician first.

When to see a doctor or go to ER

Seek urgent or emergency care if:

  • The bleeding does not stop after 15–20 minutes of firm pressure.
  • You are swallowing a lot of blood, feel faint, dizzy, or have trouble breathing.
  • The nosebleed follows a significant injury (fall, punch, car crash).
  • You are on blood thinners or have a known bleeding disorder and the bleeding seems worse than usual.

See a doctor soon (within days) if:

  • You keep getting bloody noses several times a week, or this has been going on for weeks to months.
  • The bleeding is mostly from one side of the nose every time.
  • You also have easy bruising, bleeding gums, very heavy periods, or a family history of bleeding problems.
