An adult diaper is a diaper made to be worn by a person with a body larger than that of an infant. Diapers can be necessary for adults with various conditions, such as incontinence, mobility impairment, severe diarrhea or dementia. People with medical conditions which cause them to experience urinary or fecal incontinence often require diapers or similar products because they are unable to control
their bladders or bowels. People who are bedridden or in wheelchairs, including those with good bowel and bladder control, may also wear diapers because they are unable to access the toilet independently. Those with cognitive impairment, such as dementia, may require diapers because they may not recognize their need to reach a toilet. Absorbent incontinence products come in a wide range of types (drip collectors, pads, underwear and adult diapers), each with varying capacities and sizes. The largest volume of products that is consumed falls into the lower absorbency range of products, and even when it comes to adult diapers. As such, they select products that meet their frequent-changing needs, rather than products that could be worn longer or more comfortably. Specialty diapers are required for swimming or pool therapy. These are known as swim diapers or containment swim briefs. They are intended mainly for fecal incontinence, however they can also be useful for temporary urine containment, to maintain dignity while transferring from change room to pool. The stretch allows for increased adjustability for a snug fit. They are washable and reusable. There are no disposable adult swim diapers.
