Why Do I Get Frequent Nosebleeds? Causes, Treatments and When to See a Doctor
A nosebleed (epistaxis) is a common condition that affects up to 60% of people at some point in their lives. Most nosebleeds are mild, stop on their own, and originate from the front part of the nose. However, frequent or severe nosebleeds may indicate an underlying medical condition that requires evaluation.
Dry air, allergies, frequent nose blowing, medications, and nasal injuries are among the most common causes. Less commonly, recurrent nosebleeds may be related to blood-clotting disorders, uncontrolled high blood pressure, or nasal tumors.
This guide explains the most common causes of frequent nosebleeds, how they are diagnosed, and evidence-based treatment options.
What Is a Nosebleed?
A nosebleed occurs when one or more blood vessels inside the nose rupture.
There are two main types:
Anterior Nosebleeds
These occur in the front of the nose and account for about 90% of all nosebleeds.
They are usually mild and easy to control.
Posterior Nosebleeds
These occur deeper inside the nose and are more common in older adults.
Posterior nosebleeds tend to bleed more heavily and often require urgent medical treatment.
Common Symptoms
Besides visible bleeding, you may notice:
- Blood from one or both nostrils
- Blood running down the throat
- Nasal dryness
- Crusting inside the nose
- Blocked nose
- Dizziness after heavy bleeding
- Fatigue if bleeding is frequent
What Causes Frequent Nosebleeds?
Dry Air (Most Common Cause)
Dry indoor air, especially during winter or in air-conditioned environments, can dry out the nasal lining and make blood vessels more likely to break.
Nose Picking
Frequent nose picking is one of the leading causes of recurrent nosebleeds, especially in children.
Allergies
Allergic rhinitis causes inflammation, itching, and frequent nose blowing, increasing the risk of bleeding.
Symptoms often include:
- Sneezing
- Runny nose
- Nasal congestion
- Itchy eyes
Frequent Nose Blowing
Repeated forceful blowing irritates the delicate blood vessels inside the nose.
Upper Respiratory Infections
Colds, influenza, and COVID-19 can inflame the nasal lining and increase the likelihood of bleeding.
Chronic Sinusitis
Long-term inflammation of the nasal passages and sinuses may lead to recurrent nosebleeds.
Deviated Nasal Septum
A deviated septum may dry one side of the nose more than the other, increasing irritation and bleeding.
Nasal Polyps
Large nasal polyps may occasionally contribute to irritation and recurrent bleeding.
High Blood Pressure
High blood pressure usually does not directly cause nosebleeds, but severe or poorly controlled hypertension may make heavy bleeding more difficult to stop.
Blood-Clotting Disorders
Conditions such as:
- Von Willebrand disease
- Hemophilia
- Liver disease
- Low platelet count
can increase the risk of recurrent bleeding.
Pregnancy
Hormonal changes during pregnancy increase blood flow to the nasal lining, making nosebleeds more common.
Nosebleeds as a Medication Side Effect
Several medications increase the risk of nosebleeds.
Blood Thinners (Anticoagulants)
Examples include:
- Apixaban
- Rivaroxaban
- Dabigatran
- Warfarin
These medications do not usually cause bleeding by themselves but make bleeding more difficult to stop.
Antiplatelet Medications
Examples include:
- Aspirin
- Clopidogrel
These reduce the blood’s ability to clot and may contribute to recurrent nosebleeds.
Nasal Corticosteroid Sprays
Examples include:
- Fluticasone
- Budesonide
- Mometasone
Incorrect spray technique (spraying toward the nasal septum) may increase irritation and bleeding.
Tip: Aim the spray slightly outward toward the ear on the same side, not toward the center of the nose.
Decongestant Nasal Sprays
Frequent use of sprays containing oxymetazoline or xylometazoline may dry and irritate the nasal lining.
NSAIDs
Examples include:
- Ibuprofen
- Naproxen
- Diclofenac
These may slightly increase bleeding risk.
Never stop taking prescribed blood thinners without consulting your healthcare provider.
Vitamin and Mineral Deficiencies
Vitamin C Deficiency
Vitamin C is essential for healthy blood vessels.
Severe deficiency (scurvy) can cause:
- Frequent nosebleeds
- Easy bruising
- Bleeding gums
- Poor wound healing
Vitamin K Deficiency
Vitamin K is required for normal blood clotting.
Low levels may increase bleeding.
Iron Deficiency
Frequent or heavy nosebleeds may eventually lead to iron deficiency anemia.
Symptoms include:
- Fatigue
- Weakness
- Pale skin
- Shortness of breath
Risk Factors
Your risk increases if you:
- Live in a dry climate
- Have allergies
- Frequently use nasal sprays
- Take blood thinners
- Have uncontrolled high blood pressure
- Smoke
- Have chronic sinusitis
When Should You See a Doctor?
Arrange a medical evaluation if:
- Nosebleeds occur several times each month
- Bleeding lasts longer than 20 minutes despite applying pressure
- You have recurrent bleeding from one nostril
- You bruise easily
- You have symptoms of anemia
- You take blood-thinning medication
Seek Emergency Medical Care If You Have:
- Heavy bleeding that will not stop
- Difficulty breathing because of bleeding
- Blood loss causing fainting or confusion
- A nosebleed after a significant facial injury
- A large amount of blood flowing down the throat
How Is a Nosebleed Diagnosed?
Your healthcare provider may perform:
- Medical history
- Medication review
- Blood pressure measurement
- Nasal examination
Additional tests may include:
- Nasal endoscopy
- Complete blood count (CBC)
- Clotting tests
- Iron studies
- CT scan (selected cases)
How Are Frequent Nosebleeds Treated?
Treatment depends on the cause.
Possible treatments include:
- Saline nasal spray
- Nasal moisturizing gel
- Humidifier use
- Treating allergies
- Adjusting medications (when appropriate)
- Chemical or electrical cauterization of bleeding vessels
- Nasal packing for severe bleeding
- Surgery in rare cases
How to Stop a Nosebleed at Home
- Sit upright and lean slightly forward.
- Pinch the soft part of your nose firmly with your thumb and index finger.
- Hold continuous pressure for 10–15 minutes without checking.
- Breathe through your mouth.
- Apply a cold compress to the bridge of the nose if desired.
Do not:
- Tilt your head backward.
- Lie flat.
- Blow your nose immediately after the bleeding stops.
Avoid strenuous exercise and nose blowing for 24 hours after a nosebleed.
Supplements That May Help
Vitamin C
Correcting vitamin C deficiency supports healthy blood vessels.
Vitamin K
Supplementation is only appropriate if a deficiency is confirmed or advised by a healthcare provider.
Iron
Iron supplements may be recommended if recurrent nosebleeds have caused iron deficiency anemia.
Saline Nasal Gel
Although not a dietary supplement, saline gels and moisturizing ointments can help prevent recurrent bleeding caused by dryness.

Nosebleeds in Children
Nosebleeds are common in children and are usually not a sign of a serious medical problem. Most occur in the front part of the nose (anterior nosebleeds) and stop within a few minutes with simple first aid.
Children are more likely to develop nosebleeds because the blood vessels inside the nose are delicate and can bleed easily.
Common Causes
The most common causes of nosebleeds in children include:
- Nose picking
- Dry air or heated indoor environments
- Colds and upper respiratory infections
- Allergic rhinitis (hay fever)
- Frequent nose blowing
- Minor injuries to the nose
- Irritation from smoke or other environmental irritants
Less commonly, repeated nosebleeds may be associated with blood clotting disorders, structural abnormalities of the nose, or certain medications.
What Should Parents Do?
If your child has a nosebleed:
- Keep your child calm and seated upright.
- Ask them to lean slightly forward to avoid swallowing blood.
- Pinch the soft part of the nose firmly for 10 to 15 minutes without checking too soon.
- Encourage your child to breathe through their mouth.
- After the bleeding stops, remind them not to pick, rub, or blow their nose for several hours.
Applying a cold compress to the bridge of the nose may help your child feel more comfortable, although firm pressure on the soft part of the nose is the most effective way to stop bleeding.
Preventing Nosebleeds
To reduce the risk of future nosebleeds:
- Keep the inside of the nose moist with saline nasal spray or saline gel.
- Use a humidifier if the indoor air is dry.
- Encourage your child to avoid nose picking.
- Keep fingernails trimmed short.
- Treat allergies if nasal irritation is persistent.
- Encourage gentle nose blowing during colds.
When Should You See a Doctor?
Arrange a medical evaluation if your child:
- Has frequent nosebleeds (for example, several times a week).
- Has bleeding that lasts longer than 20 minutes despite applying pressure.
- Has a nosebleed after a significant injury.
- Has nosebleeds together with easy bruising or bleeding from the gums.
- Appears pale, weak, or dizzy after bleeding.
- Has recurrent nosebleeds affecting daily life or school.
Seek emergency medical care if the bleeding is very heavy, your child has difficulty breathing, or the nosebleed follows a serious head or facial injury.
💡 Pharmacist’s Tip
Most childhood nosebleeds are caused by dryness, nose picking, or minor irritation and can be treated at home by applying firm pressure to the soft part of the nose for 10 to 15 minutes. Saline nasal sprays or gels can help keep the nasal lining moist and reduce recurrence. If nosebleeds are frequent, prolonged, or associated with unusual bruising or bleeding elsewhere, your child should be assessed by a healthcare professional.
Why do I keep getting nosebleeds?
The most common causes are dry air, allergies, frequent nose blowing, nose picking, nasal sprays, and blood-thinning medications.
Can allergies cause nosebleeds?
Yes. Allergies inflame the nasal lining, making blood vessels more likely to bleed.
Can high blood pressure cause nosebleeds?
High blood pressure is not usually the direct cause but may make severe bleeding more difficult to control.
Can blood thinners cause nosebleeds?
Yes. Anticoagulants and antiplatelet medications increase the risk and severity of bleeding.
Should I worry about frequent nosebleeds?
Repeated nosebleeds, especially from one nostril, heavy bleeding, or nosebleeds accompanied by easy bruising or anemia, should be evaluated by a healthcare provider.
Can nosebleeds in children be serious?
Most nosebleeds in children are not serious and are caused by nose picking, dry air, allergies, or colds. They usually stop within 10 to 15 minutes with firm pressure applied to the soft part of the nose. However, medical evaluation is recommended if nosebleeds are frequent, last longer than 20 minutes despite applying pressure, occur after a significant injury, or are accompanied by easy bruising, unusual bleeding, or signs of anemia.
Why does my child keep getting nosebleeds?
Recurring nosebleeds in children are often caused by dry nasal passages, nose picking, allergies, or frequent colds. Less commonly, they may be due to structural problems inside the nose, certain medications, or bleeding disorders. If your child has frequent nosebleeds or other unusual bleeding symptoms, they should be assessed by a healthcare professional.
How can I prevent nosebleeds in my child?
Keeping the inside of the nose moist with saline nasal spray or gel, using a humidifier during dry weather, treating allergies, keeping fingernails short, and discouraging nose picking can help reduce the risk of recurrent nosebleeds.
Clinical Considerations
Most recurrent nosebleeds originate from the front of the nasal septum and are associated with dryness, allergies, trauma, or medication use. A review of anticoagulant therapy, blood pressure, and nasal spray technique is important. Persistent unilateral bleeding or associated nasal obstruction warrants further evaluation to exclude structural abnormalities or, rarely, malignancy.
