Diabetes Definitions Flashcards
Diabetes mellitus
A metabolic disorder that affects how the body uses sugar (glucose)
Type 1 diabetes mellitus
An autoimmune disease that originates when cells that make insulin are destroyed by the immune system
Type 2 diabetes mellitus
A chronic condition that occurs when the body becomes resistant to insulin or when the pancreas fails to produce enough insulin
insulin
Peptide hormone produced by the beta cells of the pancreatic islets
Exogenous insulin
Insulin that comes from outside the body
Endogenous insulin
Insulin that the pancreas makes to regulate blood sugar levels
Insulin resistance
Pathological condition in which cells either fail to respond normally to the hormone insulin or downregulate insulin receptors in response to hyperinsulinemia
Insulin insufficiency
Your body makes insulin but not the amount that you need
Hypoglycemia
Low blood sugar, levels less than 70 mg/dl
Hyperglycemia
High blood sugar, levels greater than 200 mg/dl
Lipohypertrophy
Is a lump under the skin caused by accumulation of extra fat at the site of many subcutaneous injections of insulin
Glycolysis
Process through which glucose is broken down into water and carbon dioxide with the release of energy
Glycogenolysis
Refers to the breakdown of glycogen to glucose
Gluconeogenesis
Process of producing glucose from non-carbohydrate sources (protein and fat)
Glucagon
Hormone that triggers liver glucagon to convert back to glucose and use for energy
Glucose
Sugar in blood stream
Glycogen
Is the stored form of glucose (energy)
Polyuria
Excessive urine
Polyphagia
Excessive hunger/eating
Polydipsia
Intense thirst
Microvascular
Relating to the smallest blood vessels
macrovascular
Relating to the larger blood vessels
Retinopathy
Disease of the retina which results in impairment or loss of vision
Nephropathy
Damage to the small blood vessels in the glomeruli of the kidney
