What is Nutritional Rickets Treatment in Children?

Nutritional rickets is the failure of bone mineralization in growing children due to vitamin D, calcium, or phosphate deficiency. It remains one of the most common metabolic bone diseases globally and is often associated with low socioeconomic status, dark skin pigmentation, exclusive breastfeeding without supplementation, limited sunlight exposure, and dietary calcium intake below 300 mg/day.

Children present with delayed walking, leg bowing, frontal bossing, rachitic rosary, wrist widening, dental abnormalities, hypocalcemic seizures in infants, and growth failure. Diagnosis is based on radiographic features (cupping and fraying of metaphyses), low 25-OH vitamin D, low calcium or phosphate, elevated alkaline phosphatase, and elevated parathyroid hormone.

Treatment per the 2016 Global Consensus uses age-based vitamin D dosing (2000 IU/day under 1 year, 3000-6000 IU/day 1-12 years, 6000 IU/day in adolescents) for 12 weeks followed by maintenance, plus elemental calcium 500-1000 mg/day for at least three months. Severe hypocalcemia requires intravenous calcium. Prevention emphasizes routine vitamin D supplementation in all infants and at-risk children, fortified foods, and sun exposure as locally appropriate.
