In pure dwarfism, life expectancy is the same as that of a normal person. Dwarfism combined with primary or secondary diseases may affect life expectancy. Short stature is categorized into physiological short stature and pathological short stature. Physiological factors may be caused by heredity or somatic growth retardation; pathological factors are mainly caused by growth hormone deficiency, malnutrition or precocious puberty, and inherited metabolic diseases. Once short stature is found, significantly lower than the average height of normal peers, it is recommended to consult a doctor in time, according to the cause of the disease. If short stature is caused by heredity or developmental delay and other physiological reasons, it does not affect life expectancy. However, if the short stature is caused by pathological factors, it is necessary to judge whether it affects the life expectancy according to the cause of the disease. If it is only a primary decrease in the secretion of growth hormone, it basically will not affect the life expectancy; if it is caused by other diseases, it may have an effect and needs to be treated at the same time for the primary disease, such as cranio-cerebral trauma, radiotherapy, tumors and other secondary growth hormone deficiencies. Patients with short stature combined with primary or secondary diseases are recommended to go to regular hospitals for diagnosis and standardized treatment as prescribed by doctors.
