Fainting or syncope is the term used to describe a brief loss of consciousness. It is caused by a circulatory disturbance in the brain. If syncope lasts longer than a few minutes, a doctor must be consulted as soon as possible. Approximately 40% of all people will faint at least 1 time in their lives.
Unlike a real unconsciousness (coma), the life of the affected person is usually not directly threatened.
From a medical point of view, various types of syncope are distinguished.
The most common causes of fainting are a misregulation of blood pressure (vascular syncope) and diseases of the heart (cardiac syncope).
Fainting occurs due to low blood pressure (orthostasis syndrome) or circulatory insufficiency (vasovagal syncope). Blood pressure-lowering drugs, blood loss or direct irritation of the autonomic nervous system (e.g. by severe pain, blow to the neck or abdomen) can be the trigger.
Cardiac diseases can also lead to syncope, such as:
Fainting caused by hypoglycemia (low blood sugar) or anemia (anemia), no longer count as syncope.
Short-term loss of consciousness due to epileptic seizures or transient circulatory disturbances in the brain (TIA), are counted as disorders of consciousness of other causes .
