Why does a person s nose bleed for no reason

Nosebleeds are a very common symptom. This is because there is a septum in the middle of the nostrils on both sides of the nasal cavity, where several pairs of blood vessels meet, especially in the anterior and lower part of the nasal septum, there is a small area called the nasal vestibule, the small blood vessels in the nasal vestibule are densely networked, protected by a very delicate mucous membrane, so the small blood vessels are easy to rupture and bleed. When the amount of bleeding is small, the blood drips out in a punctate pattern, and when the blood is high, the blood spurts out in a columnar shape.

There are several factors that usually trigger nosebleeds:

1. The climate is dry. The nasal mucosa likes to be moist and avoid dryness, whether it is in the autumn season or in the cold wax moon season, as long as the indoor and outdoor climate is dry, it is easy to cause nosebleeds.

What are the causes of nosebleeds?

Nosebleeds have both localized and systemic causes. Trauma, inflammation, and tumors are the most common local causes. In traumatic hemorrhage, you can often know the cause of the injury, but people who often pick their nostrils with their fingers may not feel that the mucous membrane has been injured by picking their nostrils.

Inflammatory bleeding is more common in colds, flus, or acute rhinitis, and chronic atrophic rhinitis and anterior rhinitis sicca are more likely to bleed.

There are two main cases of neoplastic nosebleeds: one is hemangioma bleeding, which sometimes has a large amount of blood (hemangioma is benign and can be surgically removed**); The second is bleeding from malignant tumors (i.e., cancerous tumors), which may have small amounts of bleeding in the early stages of cancer, sometimes mixed with blood streaks only in the secretions.

Therefore, for nosebleeds, not only heavy bleeding needs to be paid attention to, but also small bleeding should be vigilant. When a small amount of nosebleeds is found, the cause of the bleeding must be carefully sought. As for systemic causes, they are mainly seen in systemic diseases.

There are many systemic diseases that can cause nosebleeds, such as arteriosclerosis, high blood pressure, vitamin insufficiency, blood diseases, thrombocytopenia, etc.

Therefore, when nosebleeds occur, the cause should not only be found locally, but also the necessary examination of the whole body in order to treat the real cause.

Common causes of nosebleeds are: good nose picking; deviated nasal septum; picky eating, lack of vitamin C or K; Hematologic pathologies such as aplastic anemia and leukemia can lead to nosebleeds.

In order to clarify the diagnosis and treatment, you should go to the otolaryngology department of a qualified hospital for treatment, first use a rhinoscope to check the local situation of the nasal cavity, if necessary, you can test the blood picture, and then deal with it as appropriate after a clear diagnosis.
