Nanosomia (Pituitary Dwarfism)

Nanosomia (Pituitary Dwarfism)In rare cases, children do not grow properly because the pituitary gland does not produce enough growth hormone (there are other causes of stunted growth, which are more common than hormone deficiency).

Growth hormone deficiency may be present from birth, but it can also occur at any time during childhood or adolescence (disease does not affect adults because they already stopped growing).

Nanosomia can be due to a pituitary tumor and other, at the moment still unknown causes. In some cases, the lack of growth hormone is accompanied by weak secretion of other hormones, leading to residual sexual development.

What to do?

In infant, dwarfism is often detected during regular inspections which undergoes every baby after birth. If something is wrong, medical examinations and blood tests will determine if the weaker growth is the result of some other cause which is more common than growth hormone deficiency. Growth hormone deficiency is detected by measuring the amount of hormones in the blood sample, both before and after stimulation of pituitary with drugs or by physical activity. Tests can determine the possible presence of a tumor of the pituitary gland.

If the cause is not a pituitary tumor, child or infant are administered human growth hormone injections twice a week. It lasts until the end of adolescence, i.e. age when normal growth ceases. Most children respond perfectly to this kind of treatment, and these children grow up in a normal healthy person.
