  3. Responses to stress and injury
  4. Internal balance of body systems (homeostasis)

Conditions that Require Emergency Care

  • Diabetes Mellitus - results from an insulin deficiency, blood sugar rises (hypoglycemia) and excess is excreted in the urine.
  • Type I - insulin dependent diabetes mellitus or juvenile onset diabetes, often caused by an inherited immune disorder that destroys pancreatic cells
  • Type II - mature onset diabetes (usually after the age of 40), often individuals are overweight, can be controlled with diet and exercise
  • Hypoglycemia - low blood sugar, can be caused by too much insulin
