    Can be caused by CAH (Congental Adrenal Hyperplasia)

  10. With Diabetes Insidipus, will production of ADH increase or decease if serum osmolarity is low? What will this cause?
    • Low serum osmolarity = Decreased ADH
    •  - Causes increased urine output
  11. With Diabetes insipidus, will ADH production increase or decrease when serum osmolarity is high? What can this cause?
    • High Osmolarity = increased ADH
    •  - This can cause increased water retention and decreased urine output
  12. Match:

    1. ADH deficiency
    2. Kidneys insensitive to normal ADH levels

    a. Central DI

  13. What is central DI and what are its causes?
    • Central diabetes insipidus is a form of DI that occurs when the body has a lower than normal amount of antidiuretic hormone (ADH). 
    • It involves extreme thirst and excessive urination.
    • - Causes: Head trauma, tumor, infection of brain, brain surgery
  14. What is Nephrogenic DI?
    In nephrogenic diabetes insipidus, the kidneys produce a large volume of dilute urine because the kidney tubules fail to respond to vasopressin (antidiuretic hormone) and are unable to reabsorb filtered water back into the body.
  15. This condition is when ADH is oveproduced, causing water retention (further causing hyponatremia d/t diluted serum levels)
    SIADH (Syndrome of Inappropriate Antidiuretic Hormone)
  16. List causes of SIADH
    tx of DI, head trauma, CNS infection, tumors, generalized seizures
  17. Fill in:
    Children who have had surgery involving the hypothalamus or pituitary will first exhibit a transient __a__, followed by a permanent DI.

    True
  19. What is the tx for SIADH
    • Correcting lytes, mainly the diluted serum sodium
    •  - fluid restrictions
    •  - Possible NaCl infusion

    2. Increased urination

    3. Fluid loss
    4. Fluid retention
