Growth retardation in children refers to the slowing down of growth rate or abnormal sequence in the process of growth and development. Part of it is related to congenital genetic factors or intrauterine dysplasia, such as familial dwarfism, late development, low birth weight children, which has a basically normal growth rate and does not require special treatment, just pay attention to the daily nutritional balance. The other part is caused by pathological reasons, such as chromosomal abnormalities, metabolic diseases, chondrodysplasia, growth hormone deficiency, hypothyroidism, chronic diseases, etc. You should go to the pediatric department of the hospital in time to have blood routine, liver function, endocrine, trace elements, X-ray and other examinations to understand the growth and development of children, so that the doctor can make a clear diagnosis. Common causes and treatment 1. Chondrodysplasia: It is a congenital developmental abnormality due to defective ossification in cartilage, mainly affecting long bones, and clinically manifests as a special type of short-limbed dwarf with good intellectual and physical development. The child’s trunk and limbs are disproportionate at birth, with a large head and short limbs and a normal trunk length. Some children can be treated with growth hormone, and if growth hormone is ineffective, leg growth surgery can be performed to increase the height of some patients. 2. Vitamin D deficiency: Vitamin D deficiency in children’s bodies causes delayed growth and development of bones and muscles, and can be supplemented with appropriate amounts of vitamin D preparations and calcium under the guidance of a doctor.
