49
What is anorexia?
Lack of appetite.
50
What does glycosuria/glucosuria indicate?
Glucose in urine; may indicate diabetes mellitus.
51
What is hyperalimentation?
Excessive intake of food; overeating.
52
What is hyperglycemia?
Excessive glucose in the blood.
53
What does ketonuria indicate?
Ketones in urine; may indicate diabetes mellitus or malnutrition.
54
What is paresthesia?
Abnormal sensation (e.g., prickling).
55
What is polydipsia?
Excessive thirst.
56
What is polyphagia?
Excessive appetite.
57
What is polyuria?

58
What is prediabetes?
Blood glucose is higher than normal but not enough to indicate diabetes.
59
What is tetany?
Continuous muscle spasms.
60
Diabetes Insipidus
Imbalance of fluid in the body resulting in uncontrollable thirst, and producing a large amount of urine
61
Addison’s Disease
also called adrenal insufficiency, an uncommon disorder that occurs when your body doesn't produce enough of certain hormones. Adrenal glands, produce too little cortisol and, often, too little aldosterone
62
Cystic Fibrosis (CF)
Hereditary Genetic disorder. Lungs and digestive system clogged with mucus. The diagnosis is based on sweat test results and/or genetic testing. CANNOT BE CURED
63
Cushing’s Syndrome
Too much cortisol in the body. Can result from over medication (corticolsteroid) or over production of cortisol or adrenocorticotropic hormone (ACTH) in the body - pituitary adenoma - ACTH-secreting tumor - Primary adrenal gland disease - Familial Cushing syndrome (Rare)
64
Grave’s Disease
Immune system disorder resulting in the overproduction of thyroid hormone. This causes swelling of thyroid gland, puffy eyes and rapid heartbeat
65
Pheochromocytoma
A rare, usually noncancerous (benign) tumor that develops in an adrenal gland. The tumor releases hormones that can cause high blood pressure, headache, sweating & panic attack symptoms
66
Goiter
An abnormal enlargement of the thyroid gland that causes coughing, difficulty breathing, hoarseness, and difficulty swallowing
67
Hyperthyroidism
overproduction of thyroid hormone aka thyrotoxicosis. Could result in a thyroid store fatal cardiac, hepatic, or renal consequences
68
Hypothyroidism
A condition in which your thyroid gland doesn't produce enough of certain crucial hormones. Also known as an underactive thyroid
69
Myxedema coma
Myxedema coma is a rare fatal condition resulting from long-standing hypothyroidism with loss of the adaptive mechanism to maintain homeostasis
