Nosebleed Causes

Nosebleed, also known as epistaxis and nasal hemorrhage, is worrisome but rarely indicative of a serious medical problem. Our nose has many blood vessels at the front and back of the nose. The blood vessels are delicate and can bleed easily. Nosebleeds are more common in children between the age of 3 and 10 years. There can be many reasons behind nosebleed, but most times they do not require medical attention. If your nosebleeding lasts longer than 10 minutes, occurs persistently day after day or occurs after an injury, you should seek medical attention.

Dry Air

One of the most common causes of nosebleeds is dry air. If you are living in a dry climate area and using a central heating system, you are at risk of nosebleeds. These two factors dry the nasal membranes and as a result the membranes become susceptible to bleeding and infections. In order to prevent nosebleeds, turn down the heat. The less dry heat you have in your house, the less susceptible you will be to nosebleeds. Moreover, you need to stay hydrated and drink enough fluid to keep your nose from drying.

Nose Picking

Nose picking is the most common cause of nosebleeds in children. The blood vessels that most often bleed are in the front part of the nasal septum (the middle part between your nostrils). These fragile blood vessels have a tendency to bleed easily when traumatized. A persistent nosebleed in children could be a sign of a bleeding disorder, such as haemophilia (a medical condition in which the blood does not clot normally).

Sinusitis is an inflammation of the nasal sinuses, which can dry out the nasal membranes and cause nosebleeds. The condition is caused by a viral or bacterial infection.Triggering of sinusitis is caused by either an allergy or an environmental irritant. There are two types of sinusitis – acute and chronic – both with complications like nasal congestion and nasal discharge. To prevent complications, you should reduce inflammation in your mucus membranes by taking a decongestant and humidify the air in your home.

Allergies can trigger nasal bleeding. Just like the common symptom (runny nose) of allergies, there can be other symptoms too. Allergy that has made your nose watery can also cause nosebleed. Constant irritation from rhinorrhea, blowing your nose, rubbing can cause wear-and-tear of the nasal tissues. Over time, this can lead to bleeding. Get your allergies under control to prevent nosebleeds.

Aspirin and Blood Thinners

One of the after-effects of the use of aspirin and blood thinners is nosebleeds. They are common in people taking anti-coagulants (blood-thinning medications, such as Aspirin). If someone is taking anti-coagulants, has hypertension (high blood pressure), or a blood-clotting disorder, nosebleeds can be difficult to contain and can last for 15 to 20 minutes. Mild allergies that affect the nose can be treated with over-the-counter medication.

Common Cold

One of the several reasons for nosebleeds is common cold. Cold can make you more likely to irritate the lining of the nose as a result of repeated blowing. Irritation of the lining of the nose along with dry winter air is what makes the ideal situation for nosebleeds. It is advised to blow your nose (especially when you have a cold) gently into a soft tissue and not forcefully or pick your nose.

Trauma to the Nose

We pick up injuries during play, sports, accidents, fights and falls. Sometimes, it may not seem like your nose is broken, but there can still be nosebleeding. If your nose bleeds after an injury and lasts for more than 10 minutes, you must see a doctor. An injury to your head, such as a blow or a fall can cause nosebleeding.
