What is Diabetes Insipidus (Arginine Vasopressin Deficiency/Resistance)?

Diabetes insipidus (DI) is defined by the inability to concentrate urine, leading to excretion of large volumes of dilute urine and compensatory polydipsia.

Central DI (AVP deficiency) results from hypothalamic-pituitary damage; nephrogenic DI (AVP resistance) results from renal tubular resistance.

Differential diagnosis includes primary polydipsia and osmotic diuresis; water deprivation or hypertonic saline with copeptin measurement is used for confirmation.

Prompt recognition prevents severe hypernatremia and dehydration, especially in hospitalized patients with altered thirst or access to water.

Symptoms

Polyuria (>3 L/day) and nocturia
Polydipsia with preference for cold water
Dehydration signs if water access is limited
Hypernatremia symptoms: lethargy, irritability, seizures
Growth failure in children with chronic unrecognized DI
Mild weight loss and fatigue

Risk Factors

Central: traumatic brain injury, pituitary surgery, craniopharyngioma, infiltrative disease (sarcoidosis, histiocytosis)
Nephrogenic: lithium therapy, chronic hypercalcemia/hypokalemia, hereditary AQP2/V2R mutations
Autoimmune hypophysitis or infundibuloneurohypophysitis
Genetic (familial central DI, Wolfram syndrome)
Pregnancy-related (transient gestational DI from placental vasopressinase)
Obstructive uropathy or sickle cell disease (partial nephrogenic)

When to See a Doctor?

If you experience any of the following symptoms, seek medical attention promptly:

  • Unexplained polyuria >3 L/day with polydipsia
  • Hypernatremia or dehydration in a patient with neurologic history
  • New polyuria after head injury, pituitary surgery, or lithium therapy

Treatment Methods

01
Confirm diagnosis with water deprivation test or hypertonic saline/copeptin stimulation
02
Central DI: desmopressin (intranasal, oral, or subcutaneous) titrated to urine output and serum sodium
03
Nephrogenic DI: adequate fluid access, low-solute diet, thiazide diuretics, NSAIDs (indomethacin), discontinue offending drugs
04
Treat underlying cause: correct electrolytes, stop lithium when possible, treat structural lesions
05
Careful perioperative management and sick-day rules to prevent hypernatremia
06
Endocrinology follow-up; family genetic counseling for hereditary forms
