A phenomenon like blood from the nose is quite common. Some people, when this symptom appears, rush to the clinic to find out its cause and check their health. Others do not attach importance to periodic nosebleeds. In most cases, this phenomenon is associated with injuries and general diseases of the body. It is possible to provoke bleeding from the nose under the influence of many factors.
The mechanism of the appearance of nosebleeds
The nose is an organ with abundant blood supply. Most often, the most superficial zone of the mucous membrane is damaged - the Kisselbach zone. This is due to the fact that there is a vascular plexus. With minor strokes of the nose or with damage to the mucosa during blowing, the Kisselbach zone is injured. Typically, 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, profuse hemorrhage is possible, leading to hemorrhagic shock and danger to human life.
The next development mechanism is associated with increased permeability of the vascular wall, due to which red blood cells freely leave the lumen. For this phenomenon, the presence of a nose injury is not necessary. Most often, it occurs with severe inflammation or blood disorders.
How to cause blood from the nose?
The causes of nosebleeds are many factors. They are divided into local and general. The first includes those reasons that are directly related to the body of smell. Most often, bleeding is caused by injuries of the nose, less often - inflammatory processes in the sinuses. With vascular weakness, it is possible with frequent and severe blowing or with unsuccessful attempts to get rid of crusts. This condition can also be observed normally, for example, during pregnancy.
Common causes include diseases in which epistaxis is one of the symptoms. These can be various conditions associated with a decrease in platelets, a violation of the strength of the 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 fear, surprise, stressful situations. So these conditions may well trigger bleeding.
How to make blood flow from your nose
Although epistaxis is a pathological condition, in some cases it may be helpful. A positive effect of it is observed with hypertensive crisis, which threatens the life of the patient. This method should not be resorted to if there are other ways to provide assistance. How to cause blood from the nose with a sharp increase in pressure?
In this case, only one option is possible - to strike. At the same time, it should be weak so as not to damage the septum and deep vascular plexuses. Bleeding from the Kisselbach zone will help reduce the amount of blood circulating in the body, as a result of which the pressure will decrease. In this case, you must definitely seek medical help and continue treating the patient with other methods.
Factors Leading to Epistaxis
In patients suffering from vascular pathologies, thrombocytopenia, hemophilia, chronic sinusitis, nosebleeds are not observed constantly, but periodically. Most often, this phenomenon is facilitated by provocative factors. How to cause blood from the nose with these diseases? Usually, the symptom is preceded by changes in the environment, such as cold, changes in atmospheric pressure (when rising into the mountains), strong winds. In addition to climatic conditions, a provoking factor may be cigarette smoke, pungent odors, and some medications.
Medicines that can cause nosebleeds include drugs that reduce coagulation (Acetylsalicylic Acid, Warfarin, Heparin) and anti-inflammatory drugs. The use of narcotic drugs can also cause this symptom.
Complications of nosebleeds
A symptom such as
nosebleeds 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 consequences can cause blood from the nose? With its large volume, the most life-threatening complication is possibly hemorrhagic shock. In this condition, a person loses a lot of fluid, blood pressure decreases significantly, all body functions suffer. If the blood volume is not restored in time, shock can lead to the death of the patient. Another complication is anemia - a decrease in hemoglobin, while the delivery of oxygen to organs and tissues is disrupted.
It should be remembered that bleeding is only a symptom, so be sure to consult a doctor and find out the cause of its appearance.
