The mechanism of nasal bleeding

The nose is an organ with abundant blood supply. Most often, the most superficial zone of the mucous membrane, the Kisselbach zone, is damaged. This is due to the fact that there is a vascular plexus there. With minor blows to the nose or damage to the mucosa during the bleeding, the Kisselbach zone is traumatized. Usually, such bleeding is insignificant in volume and does not take much time.

More dangerous are damage to the deep vascular plexuses of the nose, since they differ in duration and penetration into adjacent tissues and into the respiratory tract. In addition, with such bleeding, heavy blood loss is possible, leading to hemorrhagic shock and danger to human life.

The next development mechanism is associated with an increased permeability of the vessel wall, thanks to which the erythrocytes freely leave the lumen. For this phenomenon, there is no need to have a nose injury. Most often it occurs with severe inflammation or violations of the blood itself.

How to cause blood from the nose?

The causes of nasal bleeding are many factors. They are divided into local and general. The first include those causes that are directly related to the olfactory organ. Most often bleeding is caused by trauma to the nose, less often - inflammatory processes in the sinuses. With the weakness of the vessels it is possible with frequent and strong blowing out or with unsuccessful attempts to get rid of crusts. This condition can also be observed in normal, for example, during pregnancy.

Common causes include diseases in which nasal bleeding is one of the symptoms. It can be various conditions associated with a decrease in platelets, a violation of the strength of the blood vessels of the body. The most common cause is high blood pressure. It can be spontaneous or permanent. How to cause blood from the nose with increasing blood pressure? Hypertension is not always a disease. It can be caused by fright, surprise, stressful situation.

A positive effect from it is observed in hypertensive crisis, which threatens the life of the patient. Such a method can not be resorted to if there are other ways of providing assistance. How to cause blood from the nose with a sudden increase in pressure?

In this case, only one option is possible - to strike. At the same time, it should be not strong, so as not to damage the septum and deep vascular plexuses. Bleeding from the Kisselbach zone will help to reduce the volume of circulating blood in the body, resulting in a decrease in pressure. It is always necessary to seek medical help and continue treatment of the patient by other methods.

Factors leading to nasal bleeding

In patients suffering from vascular pathologies, thrombocytopenia, hemophilia, chronic sinusitis, bleeding from the nose is not constant, but periodically. Most often this phenomenon contributes to provoking factors. How to cause blood from the nose with these diseases? Usually the symptom is preceded by changes in the environment, for example, cold, changes in atmospheric pressure (when climbing mountains), strong wind. In addition to climatic conditions, a provoking factor may be cigarette smoke, sharp odors, some medicines.

To drugs that can cause nosebleeds, include drugs that reduce clotting ("Acetylsalicylic acid", "Warfarin", "Heparin") and anti-inflammatory drugs. The use of narcotic drugs can also cause this symptom.

Complications of nasal bleeding

Such a symptom as nasal bleeding is not always harmless and can lead to dangerous complications. In some cases, it is a sign of a disease that is difficult to diagnose (vasculitis, thrombocytopathy).

What can trigger blood from the nose consequences? With its large volume, the most life-threatening complication is a hemorrhagic shock. With this condition, a person loses a lot of fluids, blood pressure significantly decreases, all body functions suffer. If the time is not restored to the volume of blood, a shock can lead to the death of the patient. Another complication is anemia - a decrease in hemoglobin, while disrupting the delivery of oxygen to organs and tissues.

It should be remembered that bleeding is only a symptom, therefore it is absolutely necessary to consult a doctor and find out the cause of his appearance.
