What is fainting?

fainting is generally a short and unexpected loss of consciousness that can be caused by a number of factors. Sometimes fainting does not indicate serious problems, and at other times this may indicate certain dangerous physiological factors.

Often people often describe initial dull symptoms such as felt hot, maybe hear a rushing sound, a feeling of dizziness and see stains. These symptoms, if quickly resolved, can help a person. It is usually recommended that people lie on the floor with their feet slightly raised.

In some cases, fainting is easy to find too fast to stop. Before you know it, they can simply wake up on the floor a few seconds after they have fainted. This can be disorienting because the memory of how it got on the floor may be affected, and it may be difficult to understand what has just happened.

There are so many causes of faint, which sometimes makes it difficult to identify the cause. Some common causes are extreme emotional stress, too small food or drinks that lead to lowMM of blood sugar or dehydration, normally low blood pressure, excessive physical activity, tensioning of the intestine, then get up quickly or simply get up too quickly. Medical causes may include arrhythmias, heart attack, stroke, severe injuries or conditions such as narrowing aortic valve.

The

fainting is divided into several groups often defined by the cause and is often called "syncope". Vasovagal syncope tends to occur when blood pressure or heart rate is destroyed significantly. Some people tend to have vasovagal reactions to stress, like they have seen blood, injury or vision of someone else to get hurt. This type of fainting, when the vasovagal syndrome is known, is usually not dangerous.

pressure, externally on the nerves surrounding the carotid arteries, can lead to carotid sinus syncope. Some people have a very sensitive nerve ending aroundjiceH carotid arteries that can cause even a small amount of pressure to lead to fainting.

In some cases, fainting may occur directly after using the bathroom. When fainting occurs after someone is urging, the syncope is called Micturition. Other forms of fainting were associated with excessive cough or even excessive laughter. In most of these cases, blood pressure decreases rapidly and for a moment, causing loss of consciousness.

Sometimes fainting can indicate a serious condition such as stroke or heart attack. If consciousness is not restored within seconds, one should immediately alert a doctor. This is especially the case, if the person seemed to be disproportionately upset before fainting, is older or a known heart condition.
