The proposed mechanisms for somatic growth alterations in OSA involve decreased levels of insulin‐like growth factor‐I, insulin‐like growth factor binding proteins, and possibly growth hormone since serum levels are decreased in children with OSA but improve following T&A or CPAP (Bar et al., 1999; Farmarzi et al., 2016; Nieminen et al., 2002). This evidence concerns the gene GH1 and obstructive sleep apnea syndrome.
