Excess skin is an effect of surplus skin and fat after expansion during pregnancy or adipositas and following a massive and considerable weight loss. Further reasons can be aging effects, genetic disorders or an intentional expansion for skin reconstruction. Due to the elastic nature of the skin, there is generally some improvement over time. Excessive loose skin can be permanent to a degree but surgical treatment is an option.
Methods to remove excess skin by surgery include abdominoplasty, breast reduction and brachioplasty.
