Why does the nose bleed?

Most often, bleeding from the nose appears as if from scratch, a person does not have anything to hurt and nothing to worry about. But in order to prevent repeated bleeding from the nose, you need to know its causes and try to get rid of them.

Many people think that bleeding from the nose is not dangerous, and in fact it is always a sign of a deviation in the way of life or even a symptom of the disease.

Bleeding from the nose can be caused by different reasons, so, among them :

Elevated blood pressure is the most common cause of nosebleeds. Increasing the pressure of blood on the walls of fragile capillaries often breaks them, which is why the blood comes from the nose. Usually, high blood pressure is often observed in people of retirement age.

Injuries. Mechanical injuries are also one of the common causes of epistaxis. Blood can go if a person picks in the nose, or during a cold – when the nose is injured by handkerchiefs, easily traumatized vessels of the nose in ARVI swell and burst.

Drying. Drying of the mucosa occurs in the cold or in dry air indoors and can lead to bleeding.

Poor blood clotting. Bleeding from the nose can occur with poor blood coagulability, as well as those who take acetylsalicylic acid and other blood thinning drugs.

Vitamin K. Bleeding due to poor blood clotting can be associated with a lack of vitamin K. Its source is spinach, lettuce, all kinds of cabbage, avocados, bananas, wheat bran, soy, meat, eggs, milk and dairy products, olive oil.

Vitamin C. Vitamin C affects the condition of the vessels, in case of deficiency, their fragility increases. This explains the bleeding in children after illness, when the body is weakened and feels a lack of vitamins, as well as in winter and spring. Therefore, it is important to monitor food, especially after illness and during the cold season.

Polyps in the nose. Polyps are a growth in the nasal mucosa that does not allow it to function normally. The shoots interfere with breathing and exert physical pressure on the vessels. With polyps, blood from the nose goes quite often, especially in the mornings. In addition, dryness of the nose and the formation of crusts leads to scraping and new bleeding.

Vegetosovascular dystonia. If spontaneous bleeding from the nose is preceded by headache and noise in the ears, and the blood from the nose goes against the background of watery discharge, then, most likely, the cause of vegetovascular dystonia. Many people, especially children, do not tolerate weather changes, because of which blood pressure also changes dramatically, the vessels then expand, then narrow, resulting in their walls can not stand and burst.

Hormones. This reason explains the nosebleeds in girls during hormonal adjustment, this phenomenon is called replacement bleeding. Nose tissue and genital tissue – one type, it is called a cavernous tissue. If you look at it under a microscope, you can see the tightest tangle of blood vessel balls.

Therefore, when the blood flows to the genitals before the start of menstruation, the cavernous tissues of the nose are reflexively swollen, the blood vessels overflow with blood, sometimes they can not stand, burst, and blood comes from the nose.

Usually, with the establishment of a constant menstrual cycle, these problems for girls pass, but this does not prevent them from telling the endocrinologist and the gynecologist at the time of admission.

By the way, similar hormonal causes of bleeding from the nose can also be during pregnancy.

Overheating. Blood from the nose is often associated with overheating of the body, for example, in the summer with a sunstroke, and in the winter – with a rise in temperature during influenza and respiratory infections.

Sharp changes in barometric pressure. Nasal bleeding is often affected by climbers and divers due to the fact that they have to endure sudden pressure drops.

Overwork. Nasal bleeding may occur due to severe fatigue, workload or learning, in the absence of fresh air, with lack of sleep, stress and so on. As a result of all these factors, the walls of the vessels become brittle and brittle, which causes blood from the nose. Therefore, it is important to carefully monitor your lifestyle, fully rest and eat well.

In children, 90% of spontaneous nasal bleeding occurs from the Kisselbach plexus area – this is the place at the lower edge of the septum of the nose where a very dense network of branched blood vessels is located. In children, the vessels are located close to the surface, with the mucous membrane thin, so any damage to the mucosa and a sharp vasodilation can cause bleeding.
