Frequent bedwetting requires further examination at the hospital to clarify the specific causes.1. If the child is younger than 12 years old and has frequent bedwetting, further examination of neurodevelopment is required, as well as the presence of deep sleep, sacral column occlusion, and the presence of spinal cord bulge after birth, etc. If this disease is present, it may be caused by neurological developmental disorders or excessive sleep, and specialist treatment is required.2. If the bedwetting is frequent in adults, such as men, it may be chronic urinary retention due to prostate enlargement and overflow incontinence, and it is recommended to perform bladder residual urine measurement to understand whether there is urinary tract obstruction and excessive bladder residual urine caused by incontinence. In the case of women, it may be caused by stress incontinence, as women with relaxed pelvic floor muscles have a lower bladder and urethra, and the pressure of urethral closure decreases, they will experience urinary incontinence and bedwetting when using abdominal pressure.
