acromegaly
rare hormonal disorder in adulthood, usually caused by a GH-secreting pituitary tumor (adenoma) that promotes the soft tissue and bones of the face, hands, and feet to grow larger than normal
diuresis
increased formation and secretion of urine
glycosuria
abnormal amount of glucose in the urine
Graves disease
Multisystem autoimmune disorder characterized by pronounced hyperthyroidism usually associated with enlarged thyroid gland (goiter) and exophthalmos (abnormal protrusion of the eyeball)

excessive distribution of body hair, especially in women
hypercalcemia
condition in which the calcium level in the blood is higher than normal

abnormal increase in the volume of blood plasma (liquid part of the blood and lymphatic fluid) in the body
hyponatremia
lower than normal level of sodium in the blood
insulinoma
tumor of the islets of langerhans of the pancreas
obesity
excessive accumulation of fat that exceeds the body’s skeletal and physical standards, usually an increase of 20 percent or more above ideal body weight
morbid obesity
body mass index (BMI) of 40 or greater, which is generally 100 or more pounds over ideal body weight
panhypopituitarism
total pituitary impairment that brings about a progressive and general loss of hormone activity
pheochromocytoma
small chromaffin cell tumor, usually located in the adrenal medulla causing elevated heart rate and blood
thyroid storm
crisis of uncontrolled hyperthyroidism caused by the release into the bloodstream of an increased amount of thyroid hormone
virilism
Masculinization or development of male secondary sex characteristics in a woman
exophthalmometry
measures the degree of forward displacement of the eyeball as seen in Graves Disease
transsphenoidal hypophysectomy
endoscopic procedure to surgically remove a pituitary tumor through an incision in the sphenoid sinus without disturbing brain tissue

excision of one or more of the parathyroid glands usually to control hyperparathyroidism
thymectomy
excision of the thymus gland
thyroidectomy
excision of the entire thyroid gland, a part of it or a lobe
fasting blood sugar test
test that measures glucose levels in a blood sample following a fast of at least 8 hours
glucose tolerance test (GTT)
Screening test in which a dose of glucose is administered and blood samples are taken afterward at regular intervals to determine how quickly glucose is cleared from the blood
insulin tolerance test (ITT)
diagnostic test in which insulin is injected into the vein to assess pituitary function, adrenal function, and to determine insulin sensitivity
thyroid function test (TFT)
test that detects an increase or decrease in thyroid function
total calcium test
test that measures calcium to detect bone and parathyroid disorders
radioactive iodine uptake (RAIU)
administration of radioactive iodine (RAI) in pill or liquid form is used as a tracer to test how quickly the thyroid gland takes up iodine from the blood
