Nosebleeds 101: What Causes Them and What You Need to Know

Nosebleeds plague many individuals’ lives, and can be a telltale sign of a medical issue. This informative article will provide you with a comprehensive guide to nosebleeds and the possible causes.

What Are Nosebleeds?

Nosebleeds (also referred to as epistaxis) refer to any type of bleeding from the nose, ranging from mild spotting to heavy bleeding. The most common type of nosebleed, which typically affects only one nostril, originates from the front of the nose in the area known as Little’s area. This is because of the large number of blood vessels present in this location. The more severe type originates deep within the nose and may require hospitalization.

Common Causes of Nosebleeds

High blood pressure: High blood pressure (hypertension) is a risk factor for nosebleeds; however, it is also possible that a nosebleed can actually trigger changes in blood pressure. The exact mechanism is not clear, but a nosebleed will cause a person to feel dizzy, lightheaded and may lead to fainting, which can result in an increase in blood pressure.

Dry air: Living in a dry climates or using a nasal spray too often or for too long can lead to nosebleeds. Cold, dry air can cause the delicate membranes in the nose to crack and bleed.

Nasal or sinus infections: Rhinitis or sinusitis can increase mucus flow from the nostrils, which can lead to irritation of the delicate nose membranes and, as a result, nosebleeds.

Allergies and colds: Allergies can lead to frequent sneezing, which can dry and irritate the delicate membranes of the nose.

Trauma: Trauma to the nose can also cause nosebleeds, especially if the trauma involves any form of force, such as a punch or a fall.

Frequent nose picking: Frequent nose picking and forceful blowing of the nose can irritate the delicate membranes, leading to nosebleeds.

Medications: Certain medications can contribute to nosebleeds. These include anti-inflammatory and anti-platelet drugs, as well as aspirin and other non-steroidal anti-inflammatory drugs (NSAIDs).

Nosebleeds Prevention

Humidify the air: Invest in a humidifier if you live in a dry climate. This can help reduce the risk of nosebleeds by keeping the nasal passage and nasal cavity moist.

Avoid nose picking: Avoid picking and rubbing your nose too much, both of which can irritate the delicate membranes of the nose.

Protect your nose: Wear a protective mask or helmet when playing sports or doing activities that can lead to a possible nose injury.

Conclusion

Nosebleeds can be caused by a variety of different factors. Being aware of the possible causes is the first step in preventing and/or treating nosebleeds. If you experience frequent or severe nosebleeds, then it is best to consult a medical professional for further information and advice.
