More than 30 men bedwetting is not a normal condition, caused by the corresponding condition, may be related to physiological factors, such as overwork or drinking a lot of alcohol, etc.; to exclude physiological factors, may be caused by diseases, such as prostate hyperplasia, cystitis, and spinal cord lesions. 1. Physiological factors: (1) Overwork: overwork will cause a decrease in innervation ability, and sometimes involuntary urination will occur and cause corresponding symptoms. (2) Drinking a lot of alcohol: Drinking too much alcohol will cause the nerve function to be inhibited, which will further lead to the production of involuntary urination and cause the corresponding conditions. 2. Pathologic factors: (1) prostate hyperplasia: prostate hyperplasia, resulting in urinary tract obstruction, prolonged urination abnormalities, will also cause a decrease in innervation, resulting in involuntary urination. (2) Cystitis: the occurrence of chronic bladder inflammation affects the contractile function of the bladder, resulting in the production of urinary retention, and long time without recovery will also have the corresponding condition. (3) Spinal cord lesions: The presence of spinal cord lesions directly affects the state of nerve function, which can also cause the corresponding symptoms. Men in their 30s who repeatedly experience bedwetting and a decline in their physical condition need to go to a regular hospital in time to diagnose the specific physical condition and under the guidance of the clinician to carry out standardized treatment to avoid delays in the condition.
