What Causes Nosebleeds and How to Treat them

What causes nosebleeds

What causes nosebleeds? Nasal bleeding is typical. Despite being frightening, they rarely point to a significant medical issue. Numerous blood arteries may be seen at the front and rear of the nose, close to the skin’s surface. They bleed frequently and are quite brittle. Adults and children between the ages of 3 and 10 frequently get nosebleeds.

Types of Nosebleeds

There are two kinds of nosebleeds. An anterior nosebleed and a posterior nosebleed.

An anterior nosebleed occurs when the blood vessels in the front of the nose break and bleed.

A posterior nosebleed occurs in the back or the deepest part of the nose. In this case, blood flows down the back of the throat. Posterior nosebleeds can be dangerous.

Causes of nosebleeds

Nosebleeds can have a variety of reasons. Rarely is a sudden or irregular nosebleed life threatening. If you get nosebleeds frequently, you may be dealing with a more significant issue.

The most frequent cause for nosebleeds is dry air. The nasal membranes, which are tissues within the nose, can become dry by utilizing a central heating system and living in a dry environment.

This dryness causes crusting inside the nose. Crusting may itch or become irritated. If your nose is scratched or picked, it can bleed.

Antihistamines and decongestants can dry up the nasal membranes and induce nosebleeds whether taken for allergies, colds, or sinus issues. Another cause for nosebleeds is frequent blowing of the nose.

Other common causes of nosebleeds include:

  • foreign object stuck in the nose
  • chemical irritants
  • allergic reaction
  • injury to the nose
  • repeated sneezing
  • picking the nose
  • cold air
  • upper respiratory infection
  • large doses of aspirin

Other causes of nosebleeds include:

  • high blood pressure
  • bleeding disorders
  • blood clotting disorders
  • cancer

Most nosebleeds don’t need to be treated by a doctor. However, if your nosebleed persists for more than 20 minutes or happens following an accident, you should visit a doctor. This can indicate a more serious posterior nosebleed.

A fall, a vehicle accident, or a blow to the face are among the accidents that might result in a nosebleed. After-injury nosebleeds might be an indication of a broken nose, skull fracture, or internal bleeding.

Diagnosing a nosebleed

Your doctor will perform a physical examination if you go to the hospital with a nosebleed to identify the cause. They’ll look for evidence of a foreign item in your nose. Your medical background and current medicines will also be discussed.

Inform your doctor of any other symptoms you experience as well as any recent wounds. The cause of a nosebleed cannot be identified by a single test. To determine the cause, your doctor may carry out diagnostic procedures.

These tests include:

  • complete blood count (CBC), which is a blood test to check for blood disorders
  • partial thromboplastin time (PTT), which is a blood test that checks how long it takes for your blood to clot
  • nasal endoscopy
  • CT scan of the nose
  • X-ray of the face and nose

You can also apply a cold compress over the bridge of your nose or use a nasal spray decongestant to close off the small blood vessels.

If you can’t stop a nosebleed on your own, then see a doctor right away. It’s possible that you have a posterior nosebleed that needs more intensive care.

Posterior nosebleed

When you have a posterior nosebleed, your nose starts to bleed from the rear. Additionally, the blood usually runs down your throat from the back of your nose. Less often occurring and frequently more dangerous than anterior nosebleeds are posterior nosebleeds.

It is not advisable to treat posterior nosebleeds at home. If you believe you have a posterior nosebleed, call your doctor right away or go to the emergency room (ER).

Nosebleeds caused by foreign objects

If a foreign object is the cause, your doctor can remove the object.


Additionally, frequent or chronic nosebleeds can be stopped with a medical procedure called cauterization. This entails your doctor using either a heating device or the tissue-removing agent silver nitrate to burn the blood vessels in your nose.

Your doctor may pack your nose with cotton, gauze, or foam. They may also use a balloon catheter to apply pressure to your blood vessels and stop the bleeding.

How to prevent nosebleeds

There are several ways to prevent nosebleeds.

  • Use a humidifier in your house to keep the air moist.
  • Avoid picking your nose.
  • Limit your intake of aspirin, which can thin your blood and contribute to nosebleeds. Discuss this with your doctor first because the benefits of taking aspirin might outweigh the risks.
  • Use antihistamines and decongestants in moderation. These can dry out the nose.
  • Use a saline spray or gel to keep the nasal passages moist.


The majority of the time, nosebleeds are not serious. The majority are anterior nosebleeds, which are frequently treatable at home. These typically start abruptly and end quickly.

Many factors contribute to them, but dry air and frequent picking or scratching of the nose stand out. Call your doctor right away if you can’t stop the anterior nosebleed from bleeding.

A posterior nosebleed can be more serious. If you think you might have a posterior nosebleed, contact your doctor immediately or go to the Emergency Room.

One of the best methods to stop nosebleeds is to keep your home’s air humidified, refrain from picking your nose, and use nasal mists to keep your nasal passages wet.
