Type 1=HYPERGLYCEMIA (elevated blood glucose levels), POLYDIPSYA (excess thirst), polyuria (excess urination), GLYCOSURIA (glucose in the urine), dehydration, increased appetite, and weight loss.
Type 2 =GENETIC TENDENCY, increased RESISTANCE to the action of INSULIN by body
cells, and pancreatic cell defects. Characterized by ABNORMAL INSULIN SECRETION by the pancreas coupled with cellular resistance to insulin.
As body cells become more and more resistant to insulin, the pancreas adapts by producing ever increasing amounts. The pancreatic cells eventually become exhausted, and insulin production drops.
