Knowing what the causes that may be behind a fainting and as well as know their symptoms, will help us know how to act. If we have suffered an episode of fainting, should consult a doctor to rule out that there may be behind some kind of health disorder.
The faintness generally occurs in certain situations that predispose us to do so. In fact, there are people who are more likely to have fainting, even in youth. In other cases, it is a specific episode. The most common causes are related to stress, strong emotions, excessive heat, fever, and stay in an enclosed space and without ventilation, continued fasting or excessive consumption of alcoholic beverages. In some cases, it may occur after performing blood extraction.
