fainting during urination
Introduction
Introduction Urinary syncope, also known as urinating, is commonly known as "urinary halo." The main manifestation is that people suddenly fainted when they wake up at night or in the morning due to a brief loss of consciousness; there is always a short-term disturbance of consciousness, which is easy to induce urinary syncope. Mainly due to vasodilation and contraction disorders caused by hypotension, caused by a lack of brain blood supply, the patient can wake up two minutes after the occurrence of syncope, leaving no sequelae. Urinary syncope is more common in middle-aged and older men. It usually occurs at night and often happens suddenly. There is no warning before.
Cause
Cause
First, when people are urinating, a large amount of blood is concentrated in the vicinity of the bladder. The blood vessels near the bladder store a lot of blood, resulting in insufficient blood supply to the brain, which may cause syncope due to sudden ischemia and hypoxia.
Second, during the period of urinating, the human vagus nerve will emit, causing the heartbeat to slow down, and it will also cause the blood supply to the brain to decrease.
Third, the body's abdominal pressure is high before urination, but after urination, the body pressure is rapidly reduced, which will also affect the blood supply to the brain.
Fourth, when lying in bed, the body will be very relaxed, the head position is very low, from the lying position to the standing position, the adjustment of the blood vessel itself may not keep up, the blood flow can not keep up with the rhythm, can't Blood pumping into the brain is also one of the causes of cerebral ischemia.
