Why do they faint?

Causes of fainting can be covered both inshort-term malaise, and in serious diseases requiring immediate treatment. What is syncope, why this condition arises, how to recognize it and how to help a person, read on.

Causes of fainting

Fainting is a short-term loss of consciousnessas a result of cerebral circulation disorders. You can list a large number of different types of fainting, but we will dwell on a few of its most common causes.

Pathological syncope

A similar definition is given by frequent faintingconditions due to complex chronic diseases. So, for example, patients with diabetes can fall unconscious with an overdose of insulin or, conversely, skipping an injection. Also fatalities include epilepsy, ectopic pregnancy, heart attack or stroke, an asthmatic asthma attack, intoxication with substances contained in alcohol, drugs, drugs (overdose), and so on.

Vasovagal syncope

Of the total number of faints, as many as 50%this variety. Causes explaining why they faint, in this case are stress, fear (in particular, various phobias), pain, fatigue, hunger or thirst, stuffiness and so on. Often, the cause of unconsciousness can be a long-term stay near the computer, especially when it comes to a child, a teenager, a sick weakened person.

Orthostatic fainting

Similar conditions occur due to a violationnervous regulation of blood vessels. For example, if a person suddenly rose from a sitting / lying position, turned his head too fast, gave excessive physical exertion (lifted weights, re-entered the gym, ran a long distance, etc.). Faints of this nature most often occur in old people, people of any age after a serious illness with bed rest, people with low blood pressure, diseases of the cardiovascular system. Frequent orthostatic fainting may indicate a threat of stroke.

Symptoms of fainting

To understand that the loss of consciousness is approaching, it is possible both by inner self-perception and by external characteristics.

  • sharp weakness, arms and legs begin to tremble;
  • in the eyes of darkens;
  • A chill runs through my body;
  • sometimes the head may ache sharply and very much;
  • there may be pain or discomfort in the thoracic area or in the abdomen;
  • nausea is rolling.

How to recognize a pre-fog condition from:

  • he staggers.

First aid in fainting

Because to understand why a person falls infainting, correctly diagnose the cause of the disease state, and therefore effectively help the patient a simple man can not, then his main task is not to harm. And so it follows:

  • Check for a person having a pulse (if it is absent, it is not a faint).
  • Immediately call an ambulance, accurately describing the condition of the person (if there is no pulse, then this must be said - then you will need to provide first aid, saving life).
  • Gently put the person on their side - this will exclude the sinking of the tongue and further choking. If a person sits or is semi-articulated, then it is better to bring it to a flat horizontal position.
  • You can raise your legs a little.
  • Provide fresh air.
  • Wait with the person of the doctor. Do not let a person go home even if he feels better - he must be examined by a doctor. Otherwise, there is a risk of death.

Usually, loss of consciousness lasts no more than 3 minutes. After the person has come to himself, convince him to lie down quietly for a while - if he abruptly gets up, then a new syncope may follow.

It is possible, before the doctor's arrival, to conduct a basic test forstroke. To do this, ask the person to smile, stick out his tongue, say something. In stroke, most often the face and tongue are more or less distorted, the symmetry is broken, the person can not clearly and correctly pronounce the words.
