Fainting can occur in any person, even absolutely healthy. However, most often a short-term loss of consciousness occurs due to oxygen starvation of the brain, powerful emotional experiences, as a result of heart failure. Regardless of the cause, fainting is scary and dangerous. When before your eyes a person loses control of himself and just falls, it is difficult to maintain composure. In such a situation, you need to pull yourself together, stop panic and begin to act quickly and competently.
Causes of fainting
Loss of consciousness can be triggered by anything. A one-time syncope can be the result of an emotional shock or an overstrain. But if a person loses consciousness regularly, he must be examined without fail. Among the causes that can cause syncope are the following:
- Hunger. Often a person faints due to a sharp drop in blood sugar levels. This can happen after a long fast, in the process of being on a strict diet, after serious physical exertion. Sugar decreases below the permissible rate if a person does not eat carbohydrates or their amount is sharply limited. This can be observed when women sit on the so-called protein diets. Before the onset of the “hungry” fainting, the patient breathes more quickly, trembling begins, his hands are shaking, his legs are wadded, his head hurts. There is a feeling of gratuitous anxiety.
- Low hemoglobin. Loss of consciousness may occur with anemia and severe bleeding. Reducing the number of red blood cells leads to a deterioration in the blood supply to the brain. If you feel dizzy when you tilt and abruptly rise from the bed, it is worth checking the blood for hemoglobin level. Before such a swoon, a person becomes pale, a cold sweat appears. If loss of consciousness occurs due to low hemoglobin, fainting usually lasts only for a short time.
- Lack of air. When in a stuffy, closed room with a large number of people, there is an excess of carbon dioxide, which causes oxygen starvation. Removing a person from this state is not difficult - it just needs to be taken out to fresh air and wipe his face with cold water.
- Overheat. Prolonged exposure to the sun can cause heat stroke. Thermal syncope is characterized by palpitations, reddening of the skin, sweat on the body. Before fainting, a person usually experiences thirst. If the patient has lost consciousness due to overheating, it should be moved to a cool room, splashing cold water on the face.
- Disorders of the heart. With various heart diseases and low blood pressure, oxygen starvation is often recorded. As a result, and loss of consciousness occurs.
- Overwork. When a person has been working without sleep and rest for a long time, the first symptoms of approaching fainting begin to visit him - fatigue, pallor, dizziness, redness of the eyes, weak pulse, hand trembling, low blood pressure. Moreover, such symptoms may occur from both physical and mental labor. If time does not respond to the signals of the body, there may be a loss of consciousness. If a person fainted from overwork, after regaining consciousness, he needs rest and bed rest.
- Emotionality There are people who take everything to heart. Any nervous breakdown - fear, fear, pain, joy, or unexpected news can lead to a surge of emotions and cause fainting.
- Poisoning. Loss of consciousness may occur due to intoxication of the body with drugs, alcohol, various chemical compounds.
In addition, expectant mothers often faint, especially in the first trimester of pregnancy. This is due to the woman’s low pressure, hormonal alteration of her body. A pregnant woman already does not feel very well - feels nauseous, constant weakness, dizziness. And if the body is deficient in food or oxygen, it instantly reacts to this fainting state.
Is it possible to feel the approach of fainting
Of course you can. The forerunners of unconsciousness are tinnitus, black spots before eyes, cold sweat, freezing of limbs, feeling of stuffiness and lack of air, nausea, weakness. If you feel exactly these symptoms, you must immediately take a comfortable body position that will protect you from injury during a fall. Lie on your back and raise your legs to increase blood supply to the brain. If you are on the street, you need to sit on a stop or a bench and hang your head between your knees. Unfasten the top button of the shirt, loosen the tie, belt. When you feel better, you need to drink sweet tea or water.
First Aid for Fainting
What to do if a person lost consciousness right in front of your eyes? Well, if there is a doctor nearby, he will be able to provide emergency care. But do not panic, if you are facing a one-on-one problem. Correct and consistent actions will lead the patient to fainting.
- The first thing to do is to check a person's heartbeat. If not, you need to do a heart massage and artificial respiration.
- If the heartbeat is tapped (and it can be very weak), the unconscious person must be placed with his back on a flat surface. Lift your legs, substituting for them a pillow or any other object. This position ensures maximum blood flow to the brain. In no case do not lower the patient's head below the level of the body.
- The patient's head should be turned to the side so that the tongue is not sunk - this can interfere with normal breathing.
- Open the victim's collar, remove the tie, ask the onlookers to move away. So you provide the patient with enough oxygen.
- To bring the patient to his senses, you can give him a smell of ammonia. Put some ammonia on a cotton swab and bring it to your nose. If you do not have ammonia on hand, use other liquids with a strong odor - vinegar, alcohol, gasoline.
- If the strong smell does not help, you can splash cold water on the person. In no case do not hit him on the cheeks - it is absolutely useless way.
- After the patient has come to his senses, he should not make sudden movements. You need to take a comfortable posture and drink a glass of hot sweet tea.
Do not lift the patient until he regained consciousness, do not twist and shake him. If a person does not recover within 8-10 minutes, you need to call a doctor. Before the ambulance team arrives, a doctor at the other end of the line may give some advice on how to revive a person.
If a person often loses consciousness, it is necessary to consult with a doctor on this issue. Especially if fainting occurs in a child. After finding out the true cause of fainting, you need to follow general preventive measures that will avoid provoking factors. Meals should be balanced, in no case unlimited. There should be enough carbohydrates in the diet so that the glucose level does not decrease. You should eat more red meat, pomegranate, liver and dried fruits to normalize hemoglobin levels.
Loads should be moderate, but regular - take a walk in the fresh air with a calm step. This will allow you to normalize blood pressure and saturate the body with oxygen. Give up bad habits, do not neglect weekends and vacations, do not allow overheating, try not to be in cramped and closed rooms and the risk of fainting will be minimal. In addition, consult with your doctor about taking nootropics - drugs that improve the nutrition of the brain.
When a person faints before your eyes, it becomes scary. However, first aid skills should be available to everyone, even if the person is far from medicine. Often, first aid provides a further condition of the patient, and sometimes saves his life.
