, *Over secretion of ADH, Kidneys
retain water causing hypervolemia
(dilute sodium- hyponatremia)
CAUSES- cancers, lung cancer,
duodenum, etc
SIADH
Infection in lungs or CNS ->
(syndrome of
pneumonia, meningitis,
inappropriate
AVP gene mutation, any surgerys
antidiuretic
medication- Chlopropamide (oral
hormone)
antidiabetic)
Causes
S/S
S/S- THIRSTY, DEC urine (very
Treatment
concentrated) , anoerxia, (not
hungry/uncomfortable) fluid
overload, dyspnea fatigue vomiting,
hyponatremia, confusion, seizures
Treatment - Treat hyponatremia
, *DECREASED secretion of ADH,
diluted and excessive urine output,
(concentrated -> Hypernatremia,
INC plasma osmalality),
CAUSES- ** Nephrogenic -
problems with the kidneys- Genetic
(Vasopressin & Aquaphorin genes),
diseases- amyloidosis &
pylenephritis
Diabetes
Drug- lithium carbonate (can
Insuipidus (DI)
damage kidney tubules)
Patho
** Neurogenic - lesions or trauma to
Causes
hypothalamus, posterior pituitary,
S/S
TBI complications
Treatment
Pregnancy- body produces
vasopressinase which causes ADH
to break down (decrease)
S/S- polydispisa (extreme thirst), Inc
Urine output (Polyuria) diluted,
hypotension,
Treatment- If tolerable, Drink alot of
water to correct the problem
, Antidiuretic Produced by the hypothalamus
Hormone secreted and stored by the
Where is it posterior pituitary
produced? regulates the amount of water in the
Where is it body
stored/secreted (can also constrict blood vessels
? and also called vasopressin)
Normal function
(Disease of the anterior pituitary)
Cause- ischemia/infarction, edema,
adenoma, aneyursm of the pituitary
- pituitary enlarges due to edema
which causes more damage
(pituitary is in an enclosed space) ->
Tiusse damage, decreased blood
supply, fibrosis
Hypopituitarism
Dec in all pituitary hormones-
(Panhypopituitarism)
ACTH - Adrenocorticotropic
TSH- thyroid stimulating hormone
FSH & LH follicle stimulating &
Lutenizing
GH- Growth hormone
