According to statistics, 18-20% of people at least once in life happened short-term loss of consciousness. Moreover, fainting, as discharged, more often happen in the inappropriate place and at an inappropriate moment. The fainting condition is not dangerous and is only an adaptive when the body is insufficient blood supply or a brain nutrition, as it turns into mode «Energy savings». However, in some cases, fainting may indicate problems in the cardiovascular, nervous or endocrine system.
What could fainting?
- Reflex simple fainting may occur during the dysfunction of the autonomic nervous system, strong overwork, lack of sleep, sharp pain, nervous overvoltage, with long stay in the stuffy room. The mechanism of their development involves the expansion of the muscle blood vessels, the fall of blood pressure and the outflow of blood from the brain.
- Situational reflex fainting develop when coughing, swallowing, after meals, at the moment of urination or emptying of the intestine. To this type of short-term loss of consciousness include the carotid sinus syndrome, when a person falls into a condition of fainting because of the too tight collar or tight tie. Situational fainting can be orthostatic, arising at the time of a sharp transition from a horizontal position to vertical, especially after a long bed mode.
- Syncnoches can accompany diabetes mellitus, alcoholism, amyloidosis, characterized by damage to peripheral nerves and their dysfunction.
- Reception of drugs reduce blood pressure, soothing, vasodilators, tranquilizers can also cause loss of consciousness.
- The condition of the fainting may indicate a heart disease, a sharp impaired heart rhythm, damage to the arteries that feed the brain.
- Anemia, vegetative dystonia, epilepsy, stroke and a transient violation of cerebral circulation, diseases accompanied by an increase in intracranial pressure can be caused to loss of consciousness.
Despite the threatening list, I still want to note that most often it is necessary to deal with a conventional reflex faint. The loss of consciousness is always preceded by a pre-corporate state, which means to be afraid of possible fainting, it is not necessary, you should only take measures to restore the brain circulation.
Simple faint: what to do?
Simple fainting begins with boldness of consciousness, light dizziness, stall in ears, nausea, sowing, enhancement of intestinal peristals. The skin becomes a pale, arms and feet with cold and wet, on the face protruding sweat droplets, pupils expand, blood pressure drops, pulse frequent and weak. The following loss of consciousness is accompanied by a harsh weakness, a decrease in muscle tone and a soft, smooth fall.
Simply fainting usually lasts a few seconds, if the unconscious state lasts longer, single convulsive muscle twitching is possible, in rare cases — involuntary urination and defecation.
What to do, in the presence of a tendency to faint in transport, in stuffed facilities? First of all, avoid situations provoking the loss of consciousness. Do not stand for a long time, do not get up sharply, not overwork, do not tolerate pain, in short, avoid extreme physical and mental loads.
If in transport you suddenly feel the imminent faint, crush your feet and sharply strain the muscles of the hips and press. This will increase blood outflow from the limbs to the head and will prevent the loss of consciousness. If you are on the street, you can sit on one knee and lean forward, as if you tie the shoelaces.
Symptomatic fainting: how to avoid?
People prone to fainting, do not wear tight collar, ties, do not turn the head sharply and do not get up sharply.
Those who suffer from hypotension and has blood pressure below 100/60 mm, it is recommended to strengthen vessels and a vegetative nervous system. In training, contrasting souls will be helped, dumping cold water, bath, massage, sports. With the appearance of the first signs of the pre-corrosion, it is necessary to moisten the face with cold water, lie down, the head is located below the level of the body, and the legs and arms — Above, split collar.
Syncmore caused by hypoglycemia, or a decrease in blood sugar levels, often occur in humans suffering from diabetes. However, even a completely healthy person is possible «hungry» fainting when the blood glucose level falls below 2.8 mmol / l. Such light hypoglycemia happens after a large break in food or intensive physical work. She is accompanied by a sudden feeling «Brutal» hunger, not dangerous for life, and to improve the condition enough to eat a candy, drink a glass of sweet juice.
Attention! Frequent and long-term fainting, loss of consciousness, accompanied by a feeling of suffocation, severe heartbeat, fading the heart, headache indicate the need to consult a doctor.
