Aminobutyric acid usually refers to γ-aminobutyric acid in clinical practice. Some clinical studies have proved that compound γ-aminobutyric acid is effective in promoting height growth in children with short or dwarf stature by promoting increased secretion of growth hormone by the pituitary gland. Growth hormone is one of the important hormones that stimulate height growth, and γ-aminobutyric acid is an important inhibitory neurotransmitter that can promote the release of growth hormone from the pituitary gland, which can play a role in promoting height growth in children with abnormal pituitary gland function and abnormal growth hormone secretion resulting in shorter stature. Therefore, γ-aminobutyric acid can be used to promote height growth in such children after clear diagnosis. In children with normal growth hormone secretion but with delayed growth, γ-aminobutyric acid is usually not effective and may have adverse effects when administered without authorization. Height is usually related to genetics, gender, environment, and diet. Children with normal hormone levels but delayed height development can promote growth by supplementing nutrition and strengthening physical exercise: 1. Supplemental nutrition: protein, calcium and other nutrients are important substances for height growth, children with shorter stature can increase the intake of eggs, soybeans, milk, fish and shrimp in appropriate amounts to promote height growth; 2. Physical exercise: actively participate in sports and exercise to strengthen body Blood circulation, mobilize the body active, can improve the energy supply during muscle activity, promote the growth and development of muscles and bones. In addition, exercise can also stimulate the metabolism of bone cells, which helps the production of bone trabeculae and stimulates bone development, which is helpful for height growth.
