    Study Notes

    • Endocrine disorders can be diagnosed through diagnostic tests such as lab/blood tests, urinalysis, imaging tests, radioactive tests, thyroid scans, and biopsy.
    • Disorders of the anterior lobe of the pituitary gland include acromegaly, gigantism, short stature (formerly known as dwarfism), and Simmonds disease (panhypopituitarism).
    • Acromegaly is characterized by the overgrowth of growth hormone in adults, causing enlargement of cranium and lower jaw, bulging forehead, enlarged tongue, enormous hands and feet, thick lips, and large nose.
    • Gigantism occurs when excessive GH production happens prior to puberty, leading to abnormal growth in height.
    • Short stature can result from GH deficiency in childhood, causing a person to grow to only a few feet in height but with normal proportions, along with fatigue, weakness, excess body fat, decreased muscle and bone mass, cardiovascular and cerebrovascular disease, psychological disturbances, and decreased quality of life.
    • Diuretics are substances that promote diuresis, the increased production of urine, while antidiuretics help control fluid balance by reducing urination.
    • Syndrome of Inappropriate Antidiuretic Hormone (SIADH) is a condition where the body produces too much ADH, leading to water intoxication and sodium deficiency, causing symptoms such as oliguria, headache, cramps or tremors, seizures, nausea or vomiting, irritability, depressed mood, memory impairment, stupor or coma, personality changes, lethargy, increased specific gravity, and weight gain.
    • Diabetes Insipidus is a condition where the body underproduces ADH, leading to the excretion of large amounts of dilute urine, causing symptoms such as thirst, dehydration, dry mucous membranes, and low urine output.
    • Thyroid disorders include hyperthyroidism (Graves disease, exophthalmos, thyroid storm), hypothyroidism (myxedema, cretinism, goiter, Hashimoto), and disorders of the parathyroid gland (hyperparathyroidism, hypoparathyroidism).
    • Hyperparathyroidism involves increased secretion of parathyroid hormone, leading to hypercalcemia and hypophosphatemia, causing symptoms such as osteomalacia, pathological fractures, weakness, nausea and constipation, kidney stones, UTI, disorientation, and tetany.
    • Hypoparathyroidism results from inadequate circulating PTH, leading to hypocalcemia and hyperphosphatemia, causing symptoms such as tremors, muscular irritability, labyrinthian spasm, decreased cardiac output, dysrhythmias, Chvosteks and Trousseau signs.
    • Cushing's Syndrome is caused by excess cortisol in the body, leading to round and hairy appearance, buffalo hump, moon face, thin arms and legs, wavy abdomen, hyperglycemia, depression, suicidal ideations, and bone demineralization.
    • Addison's disease is a condition where the adrenal glands produce insufficient cortisol and aldosterone, leading to fatigue, weight loss, low blood pressure, and hypoglycemia.
    • Addisonian crisis is a medical emergency caused by a sudden drop in cortisol levels, leading to symptoms such as dehydration, electrolyte imbalance, hypotension, and hypoglycemia.
    • Hyperaldosteronism is a condition where the adrenal glands produce too much aldosterone, leading to increased sodium reabsorption and potassium excretion, causing symptoms such as high blood pressure, muscle cramps, and weakness.
    • Pheochromocytoma is a rare tumor of the adrenal medulla that produces and secretes excessive amounts of catecholamines, leading to symptoms such as high blood pressure, sweating, tremors, and palpitations.- Adrenal glands do not produce sufficient cortisol and aldosterone due to destruction or degeneration of the adrenal cortex.
    • Causes of Addison's disease include massive infections (e.g. tuberculosis), hemorrhage, pituitary malfunction, long-term steroid therapy, and cancer.
    • Addison's disease symptoms: dark pigmentation of skin, dehydration, hypoglycemia, hyponatremia, hyperkalemia, nausea, anorexia, hypotension, weight loss, dizziness, craving for salt, intolerance to cold, and adrenal crisis when functions reach critically low levels.
    • Glucocorticoids (cortisol) and mineralocorticoids (aldosterone) are important hormones secreted by the adrenal cortex.
    • Cortisol helps regulate metabolism, immune response, and stress response. Aldosterone helps maintain water and electrolyte balance.
    • In Addison's disease, the adrenal glands do not secrete enough cortisol, leading to hypoglycemia, dehydration, and other symptoms. They also do not secrete enough aldosterone, leading to fluid and electrolyte imbalances.
