Adult onset or acquired growth hormone deficiency, AGHD, can be triggered and accelerated by the normal decline of GH released, as one grows older. As adults age into their 30’s and 40’s there is a natural decline in Growth Hormone (GH) production and release, decreasing the amount of IGF-1 needed to live a normal healthy life. This natural decline does not necessarily mean there is a deficiency. A true GH deficiency can be caused by any disease or injury that directly impacts the pituitary glands ability to release Growth Hormone, such as a genetic condition or syndrome, traumatic brain injury (TBI) or certain types of brain tumors. Since growth hormone continues to play a vital role as we age and if a deficiency is detected, HGH can be prescribed to regain the loss of IGF-1 levels.
