What causes frequent nosebleeds and how to prevent them

I believe everyone has experienced the symptoms of nosebleeds from childhood to adulthood. This has a great impact on our physical and mental health. Although no harm can be seen in the short term, it must be a sign of some kind of disease. Therefore, let us take a detailed look at the reasons for frequent nosebleeds and how to prevent them.

What causes frequent nosebleeds?

Dry weather, nose picking, nasal inflammation, external force collision, foreign objects in the nasal cavity, certain acute infectious diseases, blood diseases, vitamin C deficiency, etc. can all cause nosebleeds. In addition, the following situations can also cause nosebleeds.

1. Trauma. Trauma to the nose and sinuses may be accompanied by fractures of the anterior cranial fossa or middle cranial fossa, damaging the anterior ethmoid artery or internal carotid artery. Bleeding is generally severe and life-threatening. Blood vessel damage during nasal or sinus surgery that is not discovered in time or not properly treated, or nose picking, forceful nose shaking, violent sneezing, foreign objects in the nasal cavity, nasal intubation, and sudden changes in air pressure that damage the nasal mucosal blood vessels can all cause bleeding.

2. Tumor. Malignant tumors of the nose, sinuses, or nasopharynx may ulcerate and bleed, with repeated small amounts of bleeding in the early stages. In the late stages, large blood vessels may be damaged and cause massive bleeding. Bleeding from benign vascular tumors such as nasopharyngeal angiofibroma and hemangioma is generally more severe. Therefore, when it comes to nosebleeds, not only heavy bleeding needs attention, but small amounts of bleeding should also raise awareness. When a small amount of nosebleed is found, the cause of the bleeding must be carefully investigated.

3. Many systemic diseases can cause nosebleeds, such as vascular sclerosis, hypertension, vitamin deficiency, blood disease, thrombocytopenia, etc. Therefore, when you have a nosebleed, you cannot just look for the cause locally, but you should also conduct necessary examinations on the whole body in order to treat the real cause.

How to prevent nosebleeds

Don't pick your nose often, because there are many nose hairs in the nostrils, which have the function of cleaning and filtering the air, and can prevent dust from entering our lungs. If we pick our noses often, the nose hairs will be damaged, and dust will enter our lungs directly, causing lung diseases. When the nostrils become dry or nasal crusts appear, we can use a cotton swab to apply some anti-inflammatory eye ointment in the nasal cavity. This can not only keep the nasal cavity dry and moisturize it, prevent nasal bleeding, but also fight some bacteria in the nasal cavity and have an anti-inflammatory effect.

In addition, you should eat more fruits and vegetables rich in vitamin C, such as kiwi, grapes, strawberries, cucumbers, etc., because vitamin C can maintain the integrity of blood vessels, reduce nasal bleeding and exudation, and is also beneficial for wound repair. You should also drink more water, because in autumn, the weather is dry and water evaporates easily. We often have dry nose, mouth and skin. Normal people generally need to drink 7 to 8 glasses of water a day to maintain normal metabolism of the human body. To prevent nasal bleeding, you must first keep the nasal cavity moist.
