Question: What is (are) Growth hormone deficiency ?
Answer: Growth hormone deficiency is characterized by abnormally short height due to lack (or shortage) of growth hormone. It can be congenital (present at birth) or acquired. Most of the time, no single clear cause can be identified. Most cases are identified in children. Although it is uncommon, growth hormone deficiency may also be diagnosed in adults. Too little growth hormone can cause short stature in children, and changes in muscle mass, cholesterol levels, and bone strength in adults. In adolescents, puberty may be delayed or absent. Treatment involves growth hormone injections.
