<prompt> Early stage of trauma is characterized byCatabolismAnabolismGlycogenesisLipolysis  <response>: Injury Phase Phase of catabolism:-- Begins at the time of injury and lasts for 2-5 days-- Phase of hypermetabolism-- Stress hormones coisol, catecholamines and glucagon and volume control hormones renin-angiotensin, aldosterone and ADH are increased. This leads to proteolysis, lipolysis, hyperglycemia and wound healing despite of negative nitrogen balance. Turning Point:-- Transient period marked physiologically by turning off of the neuroendocrine response and clinically by the appearance of getting well. Early Anabolic Phase:-- Marked by gain in muscular strength or positive nitrogen balance. Late Anabolic Phase:-- Marked by gain in weight and body fat or positive caloric balance
