What are the causes of dwarfism? I believe that many parents do not want their children to suffer from diseases such as dwarfism, once suffering from such diseases this makes parents very painful, but also to the child formed a great impact, then dwarfism is what causes it? (l) Systemic diseases: During childhood, if you suffer from chronic diseases for a long time, or have severe malnutrition, or lack of vitamins and certain trace elements, will affect growth and cause short stature. In addition, some parasitic diseases, such as schistosomiasis, hepatic schistosomiasis, hookworm disease, etc., can also cause short stature and cause dwarfism. (2) Endocrine diseases: The whole process of human growth and development is closely related to endocrine. The endocrine function disorder can affect the growth and development of children and cause short stature if some reason is formed. For example, the lack of growth hormone can cause pituitary dwarfism, and the lack of thyroid hormone can cause cretinism. There is also a lack of insulin, glucocorticoid overproduction, etc., will affect the growth of children; (3) nutritional metabolic diseases: such as slow parasitic disease, malabsorption syndrome, rickets, anti-vitamin D rickets, renal rickets, slow severe malnutrition, diabetes, etc.; (4) skeletal diseases: the growth and development of the skeleton is very important to a person’s height and body shape, once the skeleton attacked pathology, it directly affects the growth of children and adolescents, causing short stature and causing dwarfism. For example, diseases such as chondrodysplasia, multiple epiphyseal dysplasia, osteogenesis imperfecta, and crestal deformation; (5) blood circulation disorders and prolonged hypoxia: such as congenital heart disease, chronic lung disease, etc.; (6) chromosomal diseases: they are diseases caused by chromosome number anomalies or structural aberrations, and are hereditary diseases. There are many chromosomal disorders that can manifest as short stature. For example, congenital gonadal dysgenesis syndrome, catcall syndrome, etc.; (7) Other causes: Among people with short stature, there are some who are attributed to normal variants may be related to heredity. There are also many other syndromes with short stature as their presenting feature. The cause of these diseases is not understood and may be related to genetic predisposition, such as progeria.
