Many parents of children have concerns about the use of growth hormone and are afraid to talk about “hormones”. However, this is not a hormone. Growth hormone is the only effective drug approved in the United States for the treatment of dwarfism. The European Society of Pediatric Endocrinology has shown over 30 years of clinical observation that it has a very good safety profile in conventional replacement therapy. Growth hormone promotes growth, regulates bone metabolism and regulates substance metabolism, and it also has anti-aging and brain function effects. The recombinant human growth hormone produced by secretory technology using E. coli has perfect structural consistency with the growth hormone secreted by human pituitary gland. Tens of thousands of people have received long-term treatment with this drug in China, and few adverse events have been reported. Therefore, parents can use it for their children with short stature without worrying too much.
