What is the prognosis for rickets? Outcomes for children with nutritional rickets are excellent, especially if diagnosed early. Appropriate supplementation with calcium and vitamin D will lead to healing of the bony defects within days to months. [medicinenet.com]

The outlook (prognosis) is usually excellent. Both the vitamin levels and the symptoms usually respond well to treatment. However, it can take time (months) for bones to recover and for symptoms such as pain to improve. [patient.info]

Prognosis Children with rickets are likely to suffer from stunted growth, bone abnormalities and bone pain, however these symptoms often disappear with treatment. [medical-dictionary.thefreedictionary.com]

Etiology The disease is due to inactivating mutations in the CYP27B1 gene (12q14) that codes for 1-alpha-hydroxylase which converts the vitamin D precursor calcidiol to calcitriol, the vitamin D active metabolite. [orpha.net]

Etiology Vitamin D‑dependent forms Vitamin D deficiency Low exposure to UV radiation Low oral intake Low dietary intake Infants younger than 1 year: breast milk has low amounts of vitamin D (see the learning card on breast milk ) Low intestinal absorption [amboss.com]

Etiology In addition to inadequate dietary intake or malabsorption of vitamin D, deficiency can also be related to: limited sun exposure (causes include not just climate but cultural traditions such as protective or religious clothing or keeping babies [kidsnewtocanada.ca]
