Abstract

Growth hormone (GH) secretion declines during normal aging, resulting in lower circulating levels of insulin-like growth factor (IGF)-I. The mechanism for this decrement in GH status is complex. Although the physiologic sequelae to decreased somatotrope function are not fully understood, many of the catabolic changes seen in normal aging, including osteopenia, muscle atrophy, and decreased exercise tolerance, may in part be caused by the decreased action of the GH-IGF-I axis. The age-related decline in the activity of the hypothalamic-somatotrope-IGF axis may thus result in a catabolic diathesis leading to falls, fractures and frailty in the elderly, a syndrome complex which we have named “the somatopause.”
