Diabetes Flashcards
What does glucagon do
Primary role is to regulate glucose metabolism
Glucagon increase hepatic glucose output & BS concentration
4 types odd cells and fun
- Alpha cells: produce glucogan
- Beta cells: insulin & Amylin
- Delta: cell produce Somatostatin
- F & G: gastric & pancreatic peptides
What is classis anabolic hormone
Insulin, energy storing
Mech of insulin secretion
- Glucose is transported via GLUT2
- Phosphorylation occurs
- Ca influx causes release of insulin
K close - membrane depolarization
Type I DM
Juvenile
Destruction of beta cells- no circulating insulin
Glyconeogenesis & glycolysis- constant glucose delivery to blood
Adipose tissue- ketones
Metabolic acidosis
Type I DM s/s Rx
Tired, unwell, wt loss,
Polyuria, polydipsia
Ketoacidosis
Rx insulin
Inhaled insulin
Exubera
Rx for hypoglycemia
1mg glucagon IM/SC not for skinny pt
D50 IV
Type II. DM
> 90% of diabetes
Insulin production is decreased by 50%
Obesity, genetic predisposition
What’s the difference between sulfonamide & biguanides
Sulfonylamides - glyburide - inc release of insulin
Biguanides - metformin - dec hepatic production of glucose
Which PO meds for DM don’t depend on functioning pancreas
Biguanides - glucophage
Which DM PO med has black box label & why
Avandia - rosiglitozone
Fluid retention, HF
