N2 - Background/Objectives: Hypothyroidism can profoundly affect growth, particularly if it insidiously arises during early childhood. Congenital hypothyroidism is now detected through newborn screening, significantly improving the overall growth outcomes of these children. Conversely, acquired hypothyroidism often results in delayed somatic growth and shorter stature, with many affected children initially remaining non-symptomatic. The main objective of this review is to summarize the current knowledge about the impacts of acquired hypothyroidism on children’s growth outcomes. Methods: We performed a literature review to analyze growth and final height in children with acquired hypothyroidism, matching the following keywords: “hypothyroidism & growth”, “hypothyroidism & height”, “hypothyroidism & stature”, “hypothyroidism & development”, “hypothyroidism & auxological parameters”. We reviewed each article that met the eligibility criteria, and after a thorough selection, we included 16 studies. Results: Growth arrest is frequently noted as a symptom in hypothyroidic children, with substantial portions of affected children presenting below the third percentile for height. The timing of diagnosis significantly influences growth outcomes: those diagnosed during puberty tend to experience less catch-up growth due to accelerated skeletal maturation. Even if thyroxine replacement can induce rapid catch-up growth, it may be incomplete if treatment begins during puberty or if there is a markedly prolonged deficiency of thyroid hormones. While levothyroxine therapy typically results in some degree of catch-up growth, many children do not reach their expected genetic height. Conclusions: This review highlights the necessity of both early diagnosis and treatment of acquired hypothyroidism. Even if many children show improvements in height velocity post-treatment, the complete normalization of growth may remain elusive.
