The cause of faintingFainting was called fainting in medicine. The causes of fainting could be divided into physiological and pathological categories.
The physiological causes included emotional stress, overwork, hunger, rapid body position changes (such as sitting for a long time or suddenly getting up after lying for a long time, which may lead to orthostatic low blood pressure and fainting), strenuous exercise, fasting, urinating, defecation (which may cause a sudden drop in abdominal pressure, reducing blood supply to the brain and fainting), etc.
Pathological causes were mainly the following:
1. Vasodilatatory disturbances, such as orthostatic low blood pressure, voiding syncope, coughing syncope, painful syncope, carotid syndrome, simple syncope, etc.
2. Cardiogenic syncope: For example, Sick Sinus Syndrome, high-grade A-V block, and other heart rhythms; or organic cardiovascular diseases such as corona-heart disease, angina-pectoria, and myocaric-heart disease. These diseases will change hemodynamics and cause Adam-Stokes syndrome, which will lead to syncope. Cardiogenic syncope is at high risk and has a poor prognosis.
3. Brain syncope: including cerebral blood supply deficiency, cerebral hemorrhage, cerebral hemorrhage, epilepsy, etc. When there is insufficient blood supply to the brain, there will be fainting due to cerebral asphyxia. Massive cerebral hemorrhage and large-scale cerebral hemorrhage can cause a sharp increase in cerebral pressure, aggravation of cerebral edema, and fainting. There will also be fainting and loss of consciousness when there is a grand mal seizure.
4. Other reasons: such as low blood sugar, anesthesia, high altitude syncope, hyperventilation syndrome, etc.
