The cause of urinary syncope is the rapid filling of blood to the bladder after urination, which causes transient cerebral insufficiency of blood supply and low blood pressure and leads to syncope. The main measures to prevent urinary syncope are: when you get up to urinate, you should take a sitting position and rest for a while before going to urinate. Men who have frequent syncope episodes can take a squatting or sitting position to urinate. It should also be noted that one should not hold urine for too long.

It is necessary to actively regulate various chronic diseases on the body, strengthen physical exercise and outdoor activities, enhance physical fitness, and avoid alcohol abuse and overwork.
