Acidosis
a pathologic condition that results from the accumulation of acids in the body
Diabetic Ketoacidosis (DKA)
A form of hyperglycemia in uncontrolled diabetes in w hich certain acids accumulate when insulin is not available.
hemophilia
a congenital abnormality in which the body is unable to produce clots, which results in uncontrollable bleeding.
hormone
a chemical substance produced by a gland that regulates the activity of organs and tissues.
hyperglycemia
an abnormally high blood glucose level.
hyperosmolar hyperglycemic nonketotic syndrome (HHNS)
a life-threatening condition resulting from high blood glucose that typically occurs in older adults, and which causes altered mental status, dehydration, and organ damage.
hypoglycemia
an abnormally low blood glucose level
insulin
a hormone produced by the islets of langerhans (endocrine gland located throughout the pancreas) that enables glucose in the blood to enter cells; used in synthetic form to treat and control diabetes mellitus.
kussmaul respirations
deep, rapid breathing; usually the result of an accumulation of certain acids when insulin is not available in the body.
polydipsia
excessive thirst that persists for long periods, despite reasonable fluid intake; often the result of excessive urination.
polyphagia
excessive eating; in diabetes, the inability to use glucose properly can cause a sense of hunger
polyuria
the passage of an unusually large volume of urine in a given period; in diabetes, this can result from the wasting of glucose in the urine.
sickle cell disease
a hereditary disease that causes normal, round red blood cells to become oblong or sickle shaped.
symptomatic hyperglycemia
a state of unconsciousness resulting from several problems, including ketoacidosis, dehydration becasue of excessive urination, and hyperglycemia.
symptomatic hypoglycemia
severe hypoglycemmia resulting in changes in mental status.
thrombophilia
a tendency toward the development of blood clots as a result of an abnormality of the system of coagulation
thrombosis
a blood clot, either in the arterial or venous system.
type 1 diabetes
an autoimmune disorder in which the individual's immune system produces antibodies to the pancreatic beta cells, and therefore the pancreas cannot produce insulin; onset in early childhood is common.
type 2 diabetes
a condition in which insulin resistance develops in response to increased blood glucose levels; can be managed by exercise and diet modification, but is often managed by medications.
vasoocclusive crises
ischemia and pain caused by sickle-shaped red blood cells that obstruct blood flow to a portion on the body.
