Zusammenfassung:To discuss the etiology and growth consequences of small size at birth and the indications, effects, and safety of biosynthetic growth hormone therapy in children born small for gestational age. A comprehensive and non-systematic search was carried out in the PubMed, LILACS, and SciELO databases from 1980 to the present day, using the terms “small for gestational age,” “intrauterine growth restriction,” and “growth hormone”. The publications were critically selected by the authors. Although the majority of children born small for gestational age show spontaneous catch-up growth during the first two years of life, some of them remain with short stature during childhood, with high risk of short stature in adult life. Treatment with growth hormone might be indicated, preferably after 2–4 years of age, in those small for gestational age children who remain short, without catch-up growth. Treatment aims to increase growth velocity and to reach a normal height during childhood and an adult height within target height. Response to growth hormone treatment is variable, with better growth response during the pre-pubertal period. Treatment with growth hormone in short children born small for gestational age is safe and effective to improve adult height. Efforts should be done to identify the etiology of small size at birth before treatment. Discutir a etiologia e as consequências para o crescimento e as indicações, os efeitos e segurança da terapia com hormônio de crescimento biossintético em crianças pequenas para idade gestacional. Uma busca abrangente e não sistemática foi feita nas bases de dados PubMed, LILACS e SciELO de 1980 até a presente data, com os termos “small for gestational age” (pequeno para a idade gestacional), “intrauterine growth restriction” (restrição de crescimento intrauterino) e “growth hormone” (hormônio do crescimento). As publicações foram selecionadas criticamente pelos autores. Embora a maioria das crianças nascidas pequenas para idade gestacional apresente recuperação espontânea do crescimento durante os dois primeiros anos de vida, algumas delas permanecem com baixa estatura durante a infância, com alto risco de baixa estatura na vida adulta. O tratamento com hormônio de crescimento pode ser indicado, preferencialmente após os dois aos quatro anos, naquelas crianças sem recuperação espontânea do crescimento e com baixa estatura. Seus objetivos são aumentar a velocidade de crescimento e atingir uma altura normal durante a infância e um
