Addison's disease-a disease of the adrenal glands characterized by low blood pressure, weight loss, anorexia, and weakness; without replacement hormonal therapy, it is usually fatal

Autoimmune disease-condition in which the body's immune system reacts against one's own tissues or organs

Carpal tunnel syndrome-a condition in the wrist due to biomechanical factors, causing pain and burning or tingling in the fingers and hands

Hashimoto's thyroiditis-chronic inflammation of the thyroid caused by the immune system reacting against its own tissues

Hyperthyroidism-excess production of thyroid hormone due to abnormal thyroid gland function, most commonly due to stimulation by the immune system or due to a nodule

Hypothalamus-the part of the brain lying below the thalamus that regulates autonomic activities such as body temperature and certain metabolic processes

Hypothyroidism-deficiency of thyroid activity

LDL-(low density lipoprotein)-"bad cholesterol"; the higher the LDL levels in the blood, the higher the risk for coronary artery disease

L-triiodothyronine (T3)-a key thyroid hormone that is the more biologically active hormone

Myasthenia gravis-a disease affecting the muscles, including the eyes, face, lips, tongue, throat, or neck, causing muscle weakness, disability, and fatigue

Pernicious anemia-reduction in red blood cells generally occurring in later adult life due to the inability to absorb B12 from the gastrointestinal tract

Rheumatoid arthritis-a chronic disease characterized by stiffness and inflammation of the joints, loss of mobility, weakness, and deformity

Secondary hypothyroidism-thyroid underactivity due to a deficiency of pituitary TSH secretion resulting from insufficient thyrotropin releasing hormone secretion

Subclinical hypothyroidism-a mildly elevated TSH level with normal T3 and T4 levels, and either no symptoms, or very minor symptoms of hypothyroidism

Thyrotoxicosis-a toxic condition resulting from excessive amounts of thyroid hormones in the body; this occurs in hyperthyroidism

Thyroxine (T4)-an iodine-containing hormone produced by the thyroid gland to regulate metabolism; also made synthetically for treatment of thyroid disorders

TSH (thyroid stimulating hormone)-thyrotropin; a pituitary hormone that promotes the growth of and stimulates hormonal secretion of the thyroid gland
