Q5 DM Flashcards
Alpha cells secrete ____
Beta cells ____
Delta cells _____
PP cells _____
Glucagon
Insulin
Somatostatin
Pancreatic polypeptide (PP)
In an insulin resistant person, a ____ amount of insulin is needed to push glucose into cells.
Larger than usual
C-peptide in type I DM?
C-Peptide in type II DM?
Not present in T1
Present in normal or high amounts in T2
Secreted by delta cells, inhibits release of insulin and glucagon?
Stored and secreted with insulin, delays gastric emptying, regulates food intake?
Somatostatin
Amylin
T/F: Incretins are released from cells in the pancreas
Degraded by?
False. They are released in the GUT. Examples:
GIP, GLP1.
DPP-4
Normal A1C =
Prediabetic A1C
DM A1C
<5.7
5.7-6.4
>=6.5
goals for diabetics:
A1C, FBG, and 2h PPBG?
A1C <7
FBG 80-130
2h PPBG <180
Why do diabetics with high blood sugar get DKA?
without enough insulin to get glucose into the cells, the cells think they are starving so the body starts to break down fats for energy, but the ketones overwhelm.
All DM patients should lose _____
5% of body weight
T1DM basal and bolus dosing: calculate?
Calculate the total daily dose (TDD) = 0.4-0.5u/kg/day.
Usual TDD = 0.4-1u/kg/day.
Give 40-50% of TDD as basal insulin and the remaining 50-60% as bolus insulin.
Which insulins have no peak?
Long acting glargine, and degludec.
Most common SEs of insulin:
CI?
Weight gain, peripheral edema, hypoglycemia, hypoK, local injection site reactions.
Monitor for HypoK with concomitant loop diuretic use.
Metformin is a Biguanide. 1st line in DM. MOA? SE? CI? BBW?
Decrease hepatic glucose production, decrease intestinal absorption of glucose and increase sensitivity to insulin.
SE: d/n, upset stomach, vit b12 deficiency.
CI - eGFR <30, DKA, chronic metabolic acidosis.
BBW: Lactic acidosis.
Contrast procedures, HF, impaired kidney fxn can increase risk for ________ when taking metformin.
Lactic acidosis
Sulfonylureas - Glipizide, Glimepiride, Glyburide.
MOA, SE, CI
Used to be 2nd line but not anymore (does not preserve Bcell fxn)
Stimulate insulin release from pancreas
SE: Hypoglycemia, weight gain
CI: T1DM, DKA, sulfa allergies.
