Such a phenomenon, as blood from the nose, occurs quite often. Some people, when this symptom appears, rush to the clinic to find out its cause and check the health. Others do not attach importance to periodic nasal bleeding. In most cases, this phenomenon is associated with injuries and common diseases of the body. To provoke a bleeding from a nose it is possible under the influence of many factors.
Mechanism of the appearance of nasal bleeding
The nose is an organ with abundant blood supply. Most often, the most superficial zone of the mucosa, the Kisselbach zone, is damaged. This is due to the fact that there is a vascular plexus there. With minor strokes of the nose or mucosal damage during the bleeding, the Kisselbach zone is traumatized. Usually, such bleeding is insignificant in volume and does not take much time.
More serious damage to the deep vascular plexuses of the nose, as they differ in duration and penetration into adjacent tissues and in 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 increased permeability of the vessel wall, thanks to which the red blood cells 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 a number of factors. They are divided into local and general. The first include those causes that are directly related to the sense of smell. 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 an increase in blood pressure? Hypertension is not always a disease. It can be caused by fright, surprise, stressful situation. So these conditions may well provoke bleeding.
How to make the blood go from the nose
Although nosebleeds are a pathological condition, in some cases it can be useful. The positive effect of 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 reduce the volume of circulating blood in the body, resulting in the pressure decrease. It is always necessary to seek medical help and continue treatment of the patient by other methods.
Factors leading to nasal bleeding
Patients suffering from vascular pathologies, thrombocytopenia, hemophilia, chronic sinusitis, nosebleeds are not constantly, 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.
Drugs that reduce coagulability( "Acetylsalicylic acid", "Warfarin", "Heparin") and anti-inflammatory drugs are drugs that can cause nasal bleeding. The use of narcotic drugs can also cause this symptom.
Complications of nasal bleeding
This symptom, like 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 effects? With its large volume, the most life-threatening complication is possible-hemorrhagic shock. In this condition, a person loses a lot of fluid, blood pressure significantly decreases, all the functions of the body 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.
