What causes nose bleeding?

Nose bleeding is a very common problem. When it happens, you need to stop the bleeding in time so that there will be no harm to yourself. However, if you often have nose bleeding, you also need to go to the hospital for examination so that you can understand the specific situation. In this way, you can know what method is best to choose when treating it. So what is the cause of nose bleeding?

Many people do not know the causes of nose bleeding, so they don’t know what to do after nose bleeding occurs. The following is a detailed introduction so that you can have a good understanding of this problem.

What causes nose bleeding:

1. Trauma: Trauma to the nose and paranasal sinuses may be combined with fractures of the anterior cranial fossa or middle cranial fossa, damaging the anterior ethmoid artery or internal carotid artery, and generally causing severe bleeding. Picking the nose, shaking the nose forcefully, sneezing violently, foreign objects in the nasal cavity, nasal intubation, and sudden changes in air pressure can damage the nasal mucosa and blood vessels and cause bleeding.

2. Nasal and sinus inflammation: Various nasal and sinus inflammations can cause bleeding due to mucosal lesions damaging blood vessels.

3. Nasal septum lesions: Various types of nasal septum deviation, nasal septum erosion, ulcer or perforation are common causes of bleeding.

4. Tumor: Malignant tumors of the nose, sinuses or nasopharynx may ulcerate and bleed. In the early stage, there will often be repeated small amounts of bleeding. In the late stage, large blood vessels will be damaged and may cause massive bleeding. Bleeding from benign vascular tumors such as nasopharyngeal angiofibroma and hemangioma is generally more severe. Therefore, for nosebleeds, not only heavy bleeding needs attention, but small amounts of bleeding should also be of higher concern. When a small amount of nose bleeding is found, the cause of the bleeding must be carefully investigated.

Through the above introduction, we have a good understanding of the causes of nose bleeding. Therefore, after the problem of nose bleeding occurs, it must be treated. However, it should be noted that during treatment, when choosing food, some spicy foods should be reduced, as these foods can easily cause nose bleeding.
