Abstract

Critical illness is any illness, sickness or a disease or a corrective measure or situation which is life threatening or potentially life threatening.
During critical illness, the state of stress results in increased energy expenditure, hypermetabolism, hyperglycemia and muscle loss.^{(1, 2)}
The mechanisms of these successive adaptive changes are increasingly understood and are now gathered into a general theory of the metabolic response to stress.
