E N D
Gigantism • hyper GH before 25 • extreme skeletal size
Acromegaly • hyper GH during adulthood • gradual enlargement or elongation of facial bones and extremities
Pituitary Dwarfism • Hypo GH before 25 • aka proportional dwarfism • Usually normal mental & sexual functions
Cushing syndrome • hyper glucocorticoids like cortisol • fat deposits on upper back; striated pad of fat on chest and abdomen; “moon” face • may be caused by tumor of Ant. Pit (increased ACTH) • different form may be caused by hyper aldosterone (low K)
Hyperthyroidism • hyper thyroid hormone • nervous, tremor, weight loss, excessive hunger; fatigue; irritability
Graves disease • hyper thyroid hormone • inherited or possibly autoimmune • weight loss, nervousness, increased heart rate, esophthalmos goiter
Hypothyroidism • hypo thyroid hormone • sluggish, weight gain; slowing of body function
Cretinism • hypo thyroid hormone during early development • aka deformed dwarfism • retarded mental development; facial puffiness; lack of muscle coordination
Goiter • lack of iodine in diet • enlargement of thyroid
Winter depression • hyper melatonin • Usually in winter when days are shorter (sunlight inhibits melatonin) • Aka Seasonal affective disorder (SAD) • sadness resulting from exaggerated melatonin effects • expose to high-intensity light
Diabetes insipidus • hypo or insensitivity to ADH • decrease in kidney’s retention of water • excessive urination • excessive thirst
Diabetes Mellitus • “pass through honey” • Insulin allows glucose to transfer into cell • Hypo insulin OR target cell insensitivity to insulin • Hyperglycemia glycosuria polyuria polydipsia • Hyperglycemia no glucose for energy polyphagia & use of protein & fat ketoacidosis
Type I diabetes • hypo insulin due to destruction of B cells in pancreas • Inherited • sudden childhood onset • polydipsia, polyuria, weight loss, fatigue • Daily insulin injections • Aka insulin dependent daibetes mellitus (IDDM)
Type II diabetes • insensitivity to insulin or decreased production • slow adulthood onset; • genetic and environmental factors • polydispia, polyuria, overeating, fatigue • Non-insulin dependent (NIDDM) • Lifestyle change or oral hypoglycemic agents
