Pants-wetting is usually related to stress incontinence, filling incontinence, urge incontinence and other causes. 1. Stress incontinence: Stress incontinence is usually due to pelvic floor muscle relaxation or pelvic organ prolapse and other reasons, usually preferred in older patients. 2. Filling incontinence: It is usually caused by difficulty in urination, when the amount of urine in the bladder increases, it will overflow. 3. Urge incontinence: Urge incontinence is usually caused by urinary tract infection or overactive bladder syndrome. A common cause is the high sensitivity of the bladder, which sends out a voiding reflex when there is a small amount of urine, causing peeing in the pants. There are many reasons for pants-wetting, and no matter which type of incontinence you have, you need to pay attention to it and need to go to a regular hospital as soon as possible for the relevant examination and proper treatment under the doctor’s advice.
