Tip 70: hyponatraemia

Hyponatraemia is common in preterm babies, with up to a third of very low birth weight infants being hyponatraemic in the first week after birth.

This is commonly due to: impaired reabsorption of sodium at the proximal tubule; immature up-and-down regulatory mechanisms of Na+/K+/ATP pump; limited aldosterone responsiveness at the distal tubule. Intestinal absorption is also limited.
