1

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

2

diuresis

increased formation and secretion of urine

3

glycosuria

abnormal amount of glucose in the urine

4

graves disease

multisystem autoimmune disorder characterized by pronounced hyperthyroidism usually associated with enlarged thyroid gland (goiter) and exophthalmos (abnormal protrusion of the eyeball)

5

hirsutism

excessive distribution of the body hair, especially in women

6

hypercalcemia

condition in which the calcium level in the blood is higher than normal

7

hyperkalemia

condition in which the potassium level in the blood is higher than normal

8

hypervolemia

abnormal increase in the volume of blood plasma (liquid part of the blood and lymphatic fluid) in the body

9

hyponatremia

lower than normal level of sodium in the blood

10

insulinoma

tumor of the islets of langerhans of the pancreas

11

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

12

morbid obesity

body mass index (BMI) of 40 or greater, which is generally 100 or more pounds over ideal body weight

13

panhypopituitarism

total pituitary impairment that brings about a progressive and general loss of hormone activity

14

pheochromocytoma

small chromaffin cell tumor, usually located in the adrenal medulla, causing elevated heart rate and blood

15

thyroid storm

crisis of uncontrolled hyperthyroidism caused by the release into the bloodstream of an increased amount of thyroid hormone; also called thyroid crisis or thyrotoxic crisis

16

virilism

masculinization or development of male secondary sex characteristics in a women

17

exophthalmometry

Measures the degree of forward displacement of the eyeball (exophthalmos) as seen in graves disease

18

parathyroidectomy

excision of one or more of the parathyroid glands, usually to control hyperparathyroidism

19

transsphenoidal hypophysectomy

endoscopic procedure to surgically remove a pituitary tumor through an incision in the sphenoid sinus (transsphenoidal) without disturbing brain tissue

20

thymectomy

excision of the thymus gland

21

thyroidectomy

excision of the entire thyroid gland (thyroidectomy), a part of it (subtotal thyroidectomy), or a single lobe (thyroid lobectomy)

22

fasting blood sugar

test that measure glucose levels in a blood sample following a fast of at least 8 hours

23

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

24

insulin tolerance test (ITT)

diagnostic test in which insulin is injected into the veins to assess pituitary function, adrenal function, and to determine insulin sensitivity

25

thyroid function test (TFT)

test that detects an increase or decrease in thyroid function

26

total calcium test

test that measures calcium to detect bone and parathyroid disorders

27

computed tomography (CT)

imaging technique that rotates an x-ray emitter around the area to be scanned and measures the intensity of transmitted rays from different angles

28

magnetic resonance imaging (MRI)

noninvasive imaging technique that uses radio waves and a strong magnetic field, rather than an x-ray beam, to produce multiplayer cross-sectional images

29

radioactive iodine uptake (RAIU)

administration of a radioactive iodine (RAI) in pill or liquid form is used as a tracer to test how quickly the thyroid gland takes up (uptake) iodine from the blood

30

Thyroid scan

images of the thyroid gland are obtained after oral or intravenous administration of a small dose of radioactive iodine
