SIADH & ADH
Too much antidiuretic hormone (ADH)
DI Manifestations
- Polyuria - Urine output 5-20 L/day
- Polydipsia - Drinking 4-30 L/day
- Dehydration - Poor skin turgor, dry mucous membranes, hypotension, tachycardia, wt. loss, headache, dizziness, constipation
- Hypovolemic shock - hypotension, tachycardia, decreased CO, decreased cerebral perfusion
SIADH Manifestations
- Oliguria - excretion of Na+, reabsorption of water
- Fluid volume excess - wt gain w/o edema, crackles, distended neck veins, taut skin, tachycardia, HTN

- Early manifestations - headache, weakness, anorexia, muscle cramps, wt gain
- Late manifestations - personality changes, hostility, decreased deep-tendon reflexes, n&v, diarrhea, confusion, lethargy, Cheyne-Stokes respirations, seizures, coma, death
DI (Urine & Serum Concentration)
URINE DILUTE/SERUM CONCENTRATED

Urine
• Specific gravity less than 1.005
• Low osmolality (50-200 mOsm/kg)
• Decreased pH
• Decreased urine sodium
• Decreased urine potassium

Serum
• Increased serum osmolality (greater than 295 mOsm/kg)
• Increased serum sodium
• Increased serum potassium
• Serum Na+ & K+ are high only because serum is concentrated
SIADH (Urine & Serum Concentration)
URINE CONCENTRATED/SERUM DILUTE

Urine
• Specific gravity greater than 1.025
• High osmolality (greater than 295 mOsm/kg)
• Increased urine sodium
• Increased urine potassium

Serum
• Decreased serum osmolality (less than 270 mOsm/kg)
• Decreased serum sodium
• Decreased serum potassium
