Identify mechanisms that explain defects of insulin secretion & insulin action in type 2 DM
Insulin secretion defect :pulsatility, 1st phase of insulin secretion in response to glucose
-relate to abnormal function of glucokinase & ion channels.
Insulin resistance :
- Excess FFA & a disturbed adipocytokine secretion by adipose tissue insulin-signalling pathway defect
Oversecretion of glucagon & an active fatty acid oxidation in liver
-overproduction of glucose & increased gluconeogenesis.
