One of the most common risks associated with obesity is the propensity for the development of pressure ulcers and skin infections. Because excess fatty tissue prevents the body from naturally releasing heat, people that carry excess weight are prone to more profuse sweating. This perspiration builds up in the folds of the skin, most commonly under the hanging flap of tissue in the abdominal area. Because washing beneath these folds can sometimes be difficult due to the weight of the fatty folds, the constant friction and lack of cleanliness can lead to the patient suffering breakdown rashes in the skin, inflammation, lesions and skin infections. Because those that are morbidly obese have limited mobility, limited range of movement and, quite often, breathing problems, the ability to lie flat may be inhibited. Lying in one position can lead to pressure ulcers. Left untreated, pressure ulcers will result in severe and, sometimes life threatening, infection. To prevent the growth of fungus and bacteria in the folds of excess skin and to avoid the development of pressure ulcers and skin infections, careful intervention is required. Oftentimes, the excess skin must be removed surgically to prevent serious skin infections and pressure ulcers. Because the excess fat restricts adequate flood supply to the site, wound healing can be very difficult and very slow.
