Treatment of Rickets in Dietary Phosphate Deficiency and Impaired Dietary Phosphate Availability (Phosphopenic Rickets)

This protocol covers phosphopenic rickets driven by dietary phosphate deficiency or impaired dietary phosphate availability — including infants on amino acid-based elemental formulas and patients with conditions that limit phosphate absorption from the gastrointestinal tract.

Management centres on correcting the phosphate deficit through phosphate supplementation or dietary modification, with the specific form and route of intervention determined by the underlying cause.

The full protocol defines the complete intervention sequence, escalation criteria, and route-specific guidance — available below.
