What is the first medication choice for a T2D?
Metformin
How does metformin decrease BG?
1) Suppress glucose output by liver
2) Improve insulin sensitivity in peripheral tissues
3) Decrease intestinal absorption of glucose
What T2D med is well-tolerated, and does not cause weight gain or risk of hypoglycemia?
DPP-4 Inhibitors
What is insulin produced by?
Beta cells
What are the functions of insulin?
1) Stims active transport of glucose into muscle & fat cells
2) Promotes conversion of glucose to glycogen for storage
3) Stims protein synthesis
4) Promotes conversion of fatty acids into fat

Hypoglycemic agent
What kind of agent is glucagon?
Hyperglycemic agent
True or False:
Glucagon works in opposition of insulin
True
What are the counterregulatory hormones?
Cortisol
Epinephrine
Growth hormone
Why does T1DM occur (patho)?
D/t destruction of beta cells, so not enough insulin can be produced
What autoimmune diseases usually trigger T1DM?
Celiac, Crohns, and Lupus
Why does T2DM occur (patho)?
Defects at the cell membrane prevent insulin action – causing insulin resistance
