There are many causes of short stature, including: idiopathic short stature, delayed puberty, precocious puberty, small children at full term, chromosomal disorders, insufficient secretion of growth hormone and chronic diseases. If the epiphysis is closed, there is no room for growth and further examination is not necessary. If the epiphysis is not closed, endocrine function tests such as thyroid function measurement, growth hormone stimulation test, growth hormone production test, IGF-1 measurement, IGF-BP3 measurement, chromosome examination, sex hormone stimulation test, cranial magnetic resonance imaging, etc. should be done according to the condition. Only when the cause of the disease is clearly identified, the corresponding treatment can be given for different causes.
