Syncope, lipothymy or fainting are practically synonymous and are defined as loss of consciousness. In lipothymy, patients are aware that they are becoming weaker and that at any moment their body can collapse and lose consciousness. In the case of syncope, the patient suddenly loses consciousness without previous symptoms. The causes of syncope can be very diverse, from cardiovascular such as arrhythmias or cardiac conditions, to neurovascular, such as migraines and pharmacological or metabolic causes. Its treatment consists of keeping the patient with the legs elevated and the head lowered in a well-ventilated place and without too many people around. Secondly, if this is not enough, the primary cause of the patient's lymphocyte must be treated. As for treatment, there is no drug that prevents fainting.
