🗑

🗑
Diabetes Insipidus   Disorder more common in the young, caused by inadequate secretion of the antidiuretic hormone, which causes excessive thirst and excessive secretion of urine.  
🗑
Diabetes Mellitus   A common pancreatic disorder involving insulin secretion into the blood, either in too much or too little quantities, complete insulin deficiency in children caused by destruction of beta cells.

🗑
Endocrinology   The study of ductless glands, their secretions, and their function of homeostasis.  
🗑
Epinephrine   Adrenaline-produced in the adrenal medulla. Increases heart rate, fat metabolism for energy, and dilates the bronchial tubes; raises blood pressure.  
🗑

🗑
FBS   Fasting Blood Sugar.  
🗑
FSH   Follicle Stimulating Hormone.  
🗑
GH   Growth Hormone. Also known as PGH.  
🗑
Gigantism   Abnormal overgrowth of the entire body caused by hypersecretion of Pituitary Growth Hormone before puberty.  
🗑
Glucogenesis   Formation of glucose from glycogen.  
🗑
Glucagon   Hormone secreted by the pancreas which increases the amount of glucose in the blood.  
🗑
Glucocorticoids   Steroids in the adrenal cortex that influence the metabolism of fats, carbohydrates, and protiens.  
🗑
Glycogen   Substance in which carbohydrates are stored in the liver for future conversion to sugar.  
🗑
Glucose   The most important carbohydrate(sugar) in body metabolism.  
🗑
Glucosuria   Glucose in the urine.  
🗑
Graves' Disease   Disorder of the thyroid-hyperthyroidism. Characterized by abnormal weight loss, muscular weakness, and emotional instability.  
🗑
GTT   Glucose Tolerance Test  
🗑

🗑
Hormones   Secretions of endocrine glands which regulate function of the body.  
🗑
Hyperglycemia   Excessive amount of sugar in the blood.  
🗑
Hyperinsulinism   Excessive amount of insulin in the blood-insulin shock.  
🗑
Hypersecretion   Excessive secretion.  
🗑
Hypocalcemia   Abnormally low amount of calcium in the blood.  
🗑
Hypoglycemia   Too little sugar in the blood.  
🗑
Hypogonadism   Under-development of internal secretions of male sex glands.  
🗑
Hypokalemia   Extreme depletion of potassium in the blood usually lost in diuresis.  
🗑
Hyponatremia   Extreme depletion of sodium in the blood, usually through diuresis.  
🗑
Hyposecretion   Inadequate secretion.  
🗑
ICF   Intracellular fluid.  
🗑
ICSH   Interstitial cell stimulating hormone.  
🗑
Insulin   A hormone secreted by the Islets of Langerhans. Essential for metabolism of blood sugar. A hormone that lowers blood glucose levels by enabling the cell to take glucose in. Can also be made synthetically and given by injection.  
🗑
Islets of Langerhans   Clusters of cells in the pancreas which produce insulin and glucagon.  
🗑

🗑
MSH   Melanocyte Stimulating Hormone, (melanin)  
🗑
Mineralcorticoids   Hormones in the adrenal cortex that regulate water and mineral salts (electrolytes) in the body.  
🗑

🗑
Obesity   Excessive accumulation of fat in the body.  
🗑
