BIO54 MIDTERM #2: Diabetes

Diabetes

Diabetes

high level of glucose - a type of sugar- in the blood

Hyperglycemia

elevated blood glucose level

Insulin

a hormone secreted by the pancreas, stimulates cells to take up glucose from the bloodstream and carry it into the cell where it is used or stored

- without it, cells cannot take up glucose, and blood glucose levels become permanently elevated

Type 1 Diabetes

autoimmune disease in which an individual's immune system attacks and destroys normal insulin-making cells in the pancreas, it is also called insulin-dependent diabetes

- people with this require insulin injections or infusions and must carefully monitor their diet and exercise levels

- elevated glucose levels wreaks havoc with tissues and organs in the body

- damage affects kidneys, nerves in the hands and feet, and has other serious health issues

Type 2 Diabetes

- (non-insulin dependent) the pancreas does not make sufficient insulin, or body cells are resistant to its effects and don't efficiently use the insulin that is available

- 90-95% of all diabetes cases

Gestational Diabetes

state of high blood glucose during pregnancy

Fasting Plasma Glucose (FPG)

Diabetes: 126 and above

Normal: 99 and below

Oral Glucose Tolerance Test (OGTT)

Hemoglobin A1C

- gives the average value of a patient's blood glucose over the past 2-3 months, instead of at one moment in time

Diabetes: 6.5 and above

Pre-Diabetes: 5.7-6.4

Normal: 5.7 and below
