Absorbent products, sometimes called "adult diapers" help caregivers to manage incontinence in their eldery parents. Absorbent products are not a treatment of incontinence, but rather a management tool.
If your parent has incontinence, it is always important to speak to a medical professional so that they can properly rule out any serious underlying cause, and help you find the treatment option that works best for your parent. Sometimes there may not be an appropriate treatment option available that can lessen or even cure incontinence in the elderly.
