The Cause of Hypopituitary Dwarfism: Uncovered
Since that time, scientists have discovered that this condition of proportionate short stature is usually caused by a deficiency of growth hormone. It may be present from birth due to an abnormal pituitary gland (the gland that makes growth hormone) or may be part of a syndrome. It may also be acquired from brain injury, brain infections, or other diseases.Today, the condition is known as growth hormone deficiency, hypopituitary dwarfism, or hypopituitarism.
Hypopituitary Dwarfism Is Difficult to Diagnose
During the first two years of life, a child with growth hormone deficiency may grow at a normal rate. As the child becomes older, however, parents may notice that their child does not seem to be growing properly. The child is small compared to other kids his age and may look younger than them.A child who grows less than 2 inches per year, or who is only as tall as children two or more years younger, should be evaluated by a physician for growth hormone deficiency after other possible causes (such as hypothyroidism) have been ruled out. Testing for growth hormone deficiency is done by stimulating the body to produce the hormone and then measuring how much hormone is actually released.
Treatment Available
Growth hormone deficiency is treated by injections of a growth hormone preparation such as Humatrope (somatropin). A child may receive daily or weekly injections. The child's growth rate increases soon after the injections are started. The treatment continues over several years until the child's maximum growth potential is achieved. Most children will reach an "acceptable" adult height.The average adult height for someone with untreated severe growth hormone deficiency is 4 feet, 8 inches in men and 4 feet, 3 inches in women.
