Dwarfism in children, also known as dwarfism, is a group of growth disorders caused by genetic or disease factors, with complex causes, with growth hormone deficiency being more common. The child should be treated after physical examination, laboratory tests and imaging tests to clarify the cause. I. The physical examination doctor will know the absolute height values of the child and both parents to initially determine the child’s genetic height range. Parents should provide the doctor with the value of the child’s recent height growth to understand whether the annual height growth is within the normal range. Second, laboratory tests 1, through blood and urine tests to improve the liver and kidney function and some other basic indicators to determine whether the child has chronic underlying diseases, such as chronic liver disease, chronic kidney disease, chronic respiratory disease, etc.; 2, check the child’s body IGF-1 level and thyroid function, these indicators have a great relationship with the child’s growth and development; 3, but also growth hormone stimulation test, such as hypoglycemia The hypoglycemic excitation test and levodopa excitation GH test can understand the secretion of growth hormone, which is the gold standard for the diagnosis of dwarfism caused by growth hormone deficiency. Third, imaging examination is recommended to improve the X-ray examination to understand the bone age status of the child and to determine the delayed or overage bone age, which is a great guidance for the diagnosis of dwarfism. MRI of the head should also be performed to exclude organic lesions. IV. In addition to the above examinations, chromosome examination and genetic testing may be required depending on the situation to rule out the possibility of chromosomal disorders and genetic defects. If the child is indeed caused by growth hormone deficiency, growth hormone should be used under the guidance of a specialist to help grow taller. During the treatment process, attention should be paid to monitoring thyroid function and IGF-1 levels, and the child should be observed for conditions such as scoliosis during height growth.
