A child’s height is mainly regulated by genetic factors, and acquired nutrition and exercise can affect height to a certain extent. It is easy to change the influence of acquired factors on height. You can eat more foods rich in protein and calcium, such as milk, fish and shrimp, and pay attention to more exercise, which can help increase height. The hormone that has a greater impact on height increase is growth hormone, which is mainly synthesized and secreted during sleep at night, so maintaining sufficient sleep can help height development. If the parents are short, you can do manual intervention during the baby’s developmental period, injecting growth hormone to assist in increasing height, which can improve the short height due to genetic factors to a certain extent. Growth hormone injections must be applied before epiphyseal closure, and cannot increase height after epiphyseal closure. When applying growth hormone, attention should be paid to calcium supplementation to avoid inducing osteoporosis.
