Low body w eighy/ malnutrition leads to tissue breakdown and sensitivity of skin to lesion formation: moisture affects tolerance incontinent individuals are 5 times more likely to develop skin breakdown; increased sensitivity to friction and shearing. Stage i - non-blanchable erythema stage ii - partial thickness tissue loss.
