Pancreas 2 Flashcards
Where is there more genetic predisposition, DM1 or DM2?
- DM2 (90%) vs DM1 (50%)
Why are K+ levels normal or low in DM1?
- Because there is also ⬆️ ⬆️ urine loss of K+
Why are Na+ levels normal on Type 1 DM?
- ⬆️ H2O=Na+ loss
Relationship between DM1 and DM2 and hyperosmolar coma and DKA?
DM2 = hyperosmolar coma DM1= DKA
Hyperosmolar Coma Mechanism?
- ⬆️Glucose levels —> ⬆️hyperosmolarity
- Shift of H2O from ICF—> ECF
- ⬆️Polyuria
- ⬆️Water loss (dehydration)
- ⬆️Osmolarity
⬇️ICF—> COMA!!
DK mechanism?
- ⬇️Insulin
- ⬆️Lipolysis
- ⬆️Ketogenesis
At what pH does Kussmaul Breathing start?
<7.2 pH
Ratio of Hyperglycemia/ Na+ loss?
- For every ⬆️100 mg/dL of Glucose —> ⬇️1.6 mEq/L of Na
Why are DM1 patients more at risk to develop Hyperglycemia, aside from null insulin levels?
- Glucagon response is absent
How to differentiate Insulinoma hypoglycemia from exogenous use of insulin?
- C-peptide levels ⬆️⬆️ with insulinoma
2. C-peptide ⬇️⬇️ in exogenous use of insulin
Leptin is otherwise known as the _____hormone ?
Satiety hormone
Leptin is in charge of keeping us thin by 2 mechanisms, ⬇️Hunger and _____?
- Mobilizing fatty tissue
Mechanism of action of Adiponectin?
- ⬆️Insulin sensitivity
Ghrelin/Leptin and NPY relationship?
- ⬆️Ghrelin —> ⬆️NPY
2. ⬆️Leptin —> ⬇️NPY
Ghrelin levels in fat individuals?
- Actually ⬇️ dude
