Incontinence is a common and embarrassing problem which has a profound effect on social and psychological well-being. Many people wear absorbent products to contain urine and/or faeces and protect their clothes and dignity. Users of absorbent pads are very diverse, including younger women, particularly those who have had children, older men with prostate disease, people with neurological conditions and older people with mobility and mental impairment. Whilst small absorbent pads for light incontinence are adequate for some users with low volumes of urine loss, for others with higher volumes more absorbent products are needed. A practical definition of moderate-heavy incontinence is urine or faecal loss that requires a large absorbent pad (typically with a total absorbent capacity of 2000 g to 3000 g) for containment.
