Diabetes 4 Flashcards
reduced or obliterated insulin secretion
5-10% of people with diabetes
T1DM
increased insulin resistance and the inability of beta-cell to compensate for this resistance
90-95% of people with diabetes
T2DM
first surfaces during pregnancy
gestational diabetes mellitus (GDM)
blood sugar levels are higher than normal, but not yet diagnosed as type 2 diabetes
96 million adults, more than 1 in 3
pre-diabetes
3 factors that influence diabetes
- obesity
- cholesterol
- cytokines
obesity leads to __ which leads to diabetes
obesity leads to insulin resistance which leads to diabetes
high HDL, low LDL, TG lead to __ which leads to diabetes
high HDL, low LDL, TG lead to dyslipidemia which leads to diabetes
secretion of inflammatory cytokines leads to __ which leads to diabetes
secretion of inflammatory cytokines leads to immune dysfunction which leads to diabetes
2 measures of T2DM
- beta-cell dysfunction
- insulin resistance
__ can inhibit beta-cell secretion
leptin can inhibit beta-cell secretion
what amount of leptin is ideal
mid amount
U-shaped curve (too low or high is bad)
contributors to T2DM
Diabetes genes
Adipokines
Inflammation
Hyperglycemia
Free fatty acids
Other factors
what is insulin resistance?
When cells in muscle, fat, and liver don’t respond well to insulin and can’t easily take up glucose from your blood (NIDDK)
why does insulin resistance occur?
- High amounts of blood glucose cause more insulin to be secreted by the pancreas
- Over time, the organs become less responsive to the insulin, glucose builds up in bloodstream and pancreas cannot keep up with insulin demands
2 steps of insulin resistance
1) tissues unresponsive to insulin
2) impaired insulin secretion
