Most often, bleeding from the nose appears as if from scratch, nothing hurts a person and does not bother anything. But in order to prevent re-bleeding from the nose, you must 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 lifestyle or even a symptom of the disease.
Bleeding from the nose can be caused by various reasons, among them :
Increased pressure is the most common cause of nosebleeds. The increase in blood pressure on the walls of fragile capillaries often tears them apart, which is why blood from the nose comes. Usually, increased pressure is often observed in people of retirement age.
Injuries
Mechanical injuries are also one of the common causes of nosebleeds. Blood can go if a person scratched his nose, or during a runny nose - when the nose is injured by handkerchiefs, easily injured vessels of the nose with SARS swell and burst.
Drying
Drying of the mucous membranes happens in the cold or with dry air in the room and can lead to bleeding.
Poor blood clotting
Bleeding from the nose can occur with poor blood clotting, as well as for those who take acetylsalicylic acid and other blood thinning drugs.
Vitamin K
Bleeding caused by poor blood clotting may be due to vitamin K deficiency. Its source is spinach, lettuce, all types of cabbage, avocado, bananas, wheat bran, soy, meat, eggs, milk and dairy products, olive oil.
Vitamin C
Vitamin C affects the state of the blood vessels, and its deficiency increases their fragility. This explains the bleeding in children after illness, when the body is weak and feels deficient in vitamins, as well as in winter and spring. Therefore, it is important to follow the diet, especially after an illness and during the cold season.
Polyps in the nose.
Polyps are proliferation in the nasal mucosa, which prevents it from functioning normally. The processes prevent breathing and put physical pressure on the vessels. With polyps, blood from the nose goes on quite often, especially in the morning. In addition, the dryness of the nose and the formation of crusts leads to scooping and new bleeding.

Vegetative dystonia
If spontaneous bleeding from the nose is preceded by headache and tinnitus, and blood from the nose comes against the background of watery discharge, then, most likely, the cause is in vascular dystonia. Many people, especially children, do not tolerate fluctuations in the weather, because of which the blood pressure also changes dramatically, the vessels either expand or contract, as a result of which their walls do not stand up and burst.
Hormones
This reason explains the nosebleeds in girls during hormonal adjustment, this phenomenon is called replacement bleeding. The tissue of the nose and the tissue of the genitals are of the same type, it is called cavernous tissue. If you examine it under a microscope, you can see the very close intertwining of the tangles of blood vessels.
Therefore, when the blood rushes to the genitals before the start of menstruation, the cavernous tissues of the nose swell reflexively, the vessels overflow with blood, sometimes they do not stand up, burst, blood comes from the nose.
Usually, with the establishment of a permanent menstrual cycle, these problems disappear in girls, but this does not prevent the gynecologist and the endocrinologist from telling them about it during the reception.
By the way, such hormonal causes of nosebleeds can also occur during pregnancy.
Overheating
Blood from the nose is often associated with overheating of the body, for example, in summer with sunstroke, and in winter - with a rise in temperature during the flu and respiratory infections.
Barometric pressure drops
Climbers and divers often suffer from nosebleeds due to the fact that they have to endure sharp pressure drops.
Overwork
Nosebleeds may occur due to severe overwork, workload or study, in the absence of fresh air, lack of sleep, stress, and so on. As a result of all these factors, the walls of blood vessels become brittle and brittle, which causes bleeding from the nose. Therefore, it is important to carefully monitor your lifestyle, fully relax and eat well.
In children, 90% of spontaneous nasal bleeding occurs from the Kisselbach plexus zone - this is the place at the lower edge of the nasal septum, where there is a very dense network of branched blood vessels. In children, the vessels are located close to the surface, while the mucous membrane is thin, so any damage to the mucosa and a sharp expansion of the vessels can cause bleeding.
