The developmental delay depends on the type of child, whether it is a delay in growth and development, or a delay in language, neurological or motor behavior development. For children with growth retardation, the sub-degree is generally a slight delay in growth and development, and there is no disease cause, you can adjust from the diet as well as exercise, balanced and reasonable diet, appropriate increase in physical activity, and can be supplemented with drugs such as lysine vitamin B12 pellets, to adjust the problem of backward development of children in a comprehensive manner. If the problem is caused by disease, such as growth hormone deficiency, or adrenocorticotropic hormone or thyroid function disease, the problem of developmental delay can be solved only after treatment according to the disease. In the case of neurological, language, or motor developmental delay, this condition requires regular guidance and treatment at a regular child health clinic or rehabilitation clinic to address the child’s actual condition.
