Diabetes-Pino Flashcards
Diabetes
Define
Chronic disorder. Of metabolism (carbs, fat)
Absolute/relative deficiency of insulin secretion
Ineffective response to insulin
Hyperglycemia
T1DM
Gene ass
HLA
DM
Risk factors
Viruses
Diet
Higher SES
Obesity
Vit D deficiency
Insulin
Get carbs into cell
Opens receptors for glucose
conversion of glucose to glycogen
T1DM
Pathogenesis
Genetic (HLA DR3/4) + environmental trigger
DM
Presentation
Polyuria
Polydipsia
Polyphagia (w weight loss)
Can be DKA
DM
Why do you get polyuria, polydipsia, polyphagia
Glucose goes above renal threshold. Goes into urine so draws water with it. Causes you to drink more.
Cells starve due to no glucose (no uptake). Cells shift to fat (polyphagia w weight loss)
