My son is currently being investigated for CF due to repeat lung infections, 2 episodes of acidosis with hyponatremia and now reduced growth. He's had respiratory issues since he was 3 or 4 months old, but grew very well until more recently. Can growth issues happen later, or do they usually start right away? It seems weird to me that he'd be a big kid for 6 years, then suddenly slow way down! He used to be in the 95th percentile for height, and is now at the 50th. He's also being investigated for adrenal issues since his cortisol is very low. Thanks for any thoughts.
