Nose Bleeds: 8 Common Causes & What to Do

Updated in January 2023

Nose bleeds are often a result of injuries from direct trauma or from objects lodged in the nose. However, they may be a sign of another health condition, like high blood pressure, low platelets or hemophilia.

Nose bleeds occur because the nasal lining contains tiny blood vessels that are close to the surface and can be easily damaged. Slight bumps to the nose and changes in the air, especially when the environment becomes drier, can make the nasal membrane more susceptible to nose bleeds.

Nose bleeds can be easily treated with direct pressure and cold compresses to the bridge of the nose. However, you should see a doctor for assessment if nose bleeds are frequent or hard to clot, or if they occur with symptoms like dizziness, fever or vomiting.

What causes nose bleeds?

Nose bleeds can occur for the following reasons:

1. Direct trauma

Nose bleeds can occur with nose injury, like a strong blow to the nose or a broken nose. A fracture happens when the nasal bones break or cartilage tears, and this can result in nose bleeds. Other symptoms include swelling of the nose, bruising around the eyes, sensitivity to touch, visible deformity and difficulty breathing.

What to do: Generally, treatment should be received in a hospital setting. It involves managing symptoms with analgesics and anti-inflammatories. Surgery may be necessary to realign the bones. Recovery usually takes about 7 days. In some cases, the entire nose needs to be corrected.

2. High blood pressure

Normally, high blood pressure does not present with any symptoms, but they can start to emerge if blood pressure exceeds 140/90 mmHg. In these cases, you may experience nausea, dizziness, strong headache, nose bleeds, ringing in the ears, shortness of breath, excessive fatigue, blurred vision and chest pain. Learn more about the symptoms associated with high blood pressure. 

What to do: Once high blood pressure is diagnosed, it should be monitored by the doctor. Mild cases can be managed with diet changes, by reducing salt and fat intake for example. More severe cases may require prescription medication to decrease blood pressure. Check out these natural remedies for high blood pressure that can complement prescribed therapy. 

3. Objects in the nose 

Sometimes, particularly in babies and children, nosebleeds can occur due to objects stick in the nose, like small toys, pieces of food, or garbage. In addition to nose bleeds, other symptoms can occur like discomfort and difficulty breathing. 

What to do: You should gently try to blow your nose or very carefully remove the object using tweezers without further lodging it in. If these do not resolve the problem within a few minutes, you should proceed to the emergency room for a health care professional to remove the object safely. You should try to remain calm and breathe through the nose so that the object is not inhaled any further. 

It is very important to keep small objects out of reach of babies and children, and to keep them under supervision, especially during meals. 

4. Low platelets

People who have a low platelet count will have higher risk for bleeding, as they have a lower capacity for blood clotting. They can have symptoms like bruising, redness in the skin, bleeding gums, nose bleeds, blood in the urine or stool, heavy periods and wounds with hard-to-control bleeding.

What to do: Treatment for a low platelet count will depend on the cause, therefore it should be assessed by your family doctor or a hematologist. Treatment may involve the use of medications or even a platelet transfusion. 

5. Deviated septum

A deviated septum can occur for many reasons, like previous trauma to the nose, local inflammation or birth defects. It decreases the width of the nostrils, and can cause difficulty breathing, sinusitis, fatigue, nose bleeds and difficulty sleeping due to snoring. 

What to do: This can generally be corrected with a simple surgery. 

6. Hemophilia

Hemophilia is a genetic and hereditary illness that results in clotting abnormalities. Common symptoms include bruising, joint swelling, joint pain spontaneous nose or gum bleeding, and difficult-to-control hemorrhaging. Even a small cut may result in heavy bleeding, and menstruation is often excessive and prolonged.

What to do: Although it does not have a cure, hemophilia can be treated with coagulation factors that the body is lacking, like factor factor VIII in hemophilia A, and factor IX in hemophilia B. 

7. Sinusitis

Sinusitis is an inflammation of the nasal cavities. It can cause nose bleeds, headaches, and a feeling of facial heaviness, especially around the forehead and cheeks. Generally, sinusitis is caused by an influenza virus, but it can also be caused by the growth of bacteria within nasal secretions, which become stuck in the sinuses. Learn more about the symptoms associated with a sinus infection.

What to do: Treatment should be monitored by a doctor, and usually consists of nasal sprays, analgesics, oral steroids or antibiotics. Check out ways you can relieve symptoms of sinusitis at home.

8. Medication use

Frequent use of some types of medications, like nasal sprays for allergies, anticoagulants or aspirin can interfere with blood clotting and cause easy bleeding, even in the nose. 

What to do: If the nose bleed causes a lot of discomfort or occurs frequently, you should speak to you doctor to discuss the benefits and risks of the medication and assess whether there is an alternative available.

When to see a doctor 

Nose bleeds should be assessed by a doctor when:

  • Bleeding does not stop within 30 minutes 
  • They occur frequently and interrupt activities of daily living, like going to work, sleeping or exercising 
  • You take medication to prevent clots or thin your blood 

You should proceed directly to a hospital if you have a nosebleed that does not clot and you estimate it can fill a cup with blood. You should additionally seek urgent attention if your nosebleed causes symptoms like dizziness, palpitations, shortness of breath.
