ketoacidosis
diabetic ketoaciosis (DKA)
Definition
presence of an abnormal amount of ketone bodies (acetone, betahydroxybutyris acid, and acetoacetic acid) in the blood and uring indicating an abnormal use of carbs, such as an uncontrolled diabeties and starvation
Term

Definition
excessive thirst
Term
polyuria
Definition

Term
diabetes mellitus
Definition
metabolic disorder caused by the absence or insufficient production of insulin secreted by the pancreas resulting in hyperglycemia and glycosuria
Term
type 1 diabetes mellitus
Definition
diabetes in which there is no beta cell production of insulin, and the patient is dependend on insulin for survival
Term
type 2 diabetes mellitus
Definition
diabetes in which either the body does not produce enough insulin or there is insulin resistance (a defective use of the insulin that is produced); the patient is usually not dependent on insulin for survival
Term
pancreatitis
Definition
inflammation of the pancreas
Term
acromegaly
Definition
disease characterized by enlarged features, esp the face and hands, caused by hypersecretion of the pituitary growth hormone after puberty, when normal bone growth has stopped; most often caused by a pituitary tumor
Term
pituitary dwarfism
Definition
condition of congenital hyposecretion of growth hormone slowing growth and causing short yet proportionate stature (not affecting intelligence), often treated during childhood with growth hormone
Term
pituitary giantism
Definition
condition of hypersecretion of growth hormone during childhood bone development that leads to bone overgrowth, esp in the long bones, most often caused by a pituitary tumor
Term
goiter
Definition
enlargement of the thyroid gland caused by thyroid dysfunction, tumor, of lack of iodine in the diet, or inflammation (goiter = throat)
