Fainting is a simple term in common use that is used to describe a loss of consciousness that can occur at any time in life for countless reasons, more or less serious and worrisome.
Except in cases in which it is triggered by definitely non-pathological phenomena, such as standing and standing still for a long time in a very hot environment, fainting always deserves to be brought to the attention of the family doctor or an emergency health service (Medical Guard, Emergency Room), depending on the associated symptoms, the age and characteristics of the patient, and the circumstances under which it occurred.
