Urinary incontinence with constant dribbling is related to abnormalities in the bladder itself as well as in the surrounding tissue structure. Common causes include abnormal pelvic floor muscle function, abnormal nerve function, and obstructive lesions. 1. Abnormal pelvic floor muscle function: Childbirth, aging or trauma causes abnormal pelvic floor muscle function and decreased bladder sphincter function, which will lead to the corresponding condition. 2. Abnormal nerve function: direct nerve injury or various reasons affecting the abnormal function of the nerves innervating the bladder can cause related symptoms. 3. Obstructive lesions: mainly occurring in men, prostate hyperplasia, prostate cancer and other diseases, affecting the smoothness of the urinary tract, can cause related symptoms. When urinary incontinence is accompanied by other symptoms, it is necessary to consult a doctor in time to observe and diagnose the cause of the disease and then carry out standardized treatment under the guidance of the clinician to avoid delaying the condition.
