Why Hormones Decline?
At age 21, we have ten times more growth hormone in our blood than at age 60. This hormone decline accelerates in our thirties (about 14% per decade after age 25) and consequently, the obvious signs of aging. The complex endocrine system of our body controls the hormones that regulate many body processes. As we age, these systems become less efficient, leading to changes in our bodies such as menopause and andropause. After age 35, our body continues to manufacture human growth hormone (HGH) but releases less of it. The decline of HGH with age, sometimes referred to as somatopause, is directly associated with many of the symptoms of aging such as: gray hair, shrinking of organs (i.e. brain, kidneys; heart), increased risk of cardiovascular disease and osteoporosis. It should be understood that aging (or senescence) changes are frequently associated with an increase in likelihood of mortality, but this is not necessarily the case. For example, graying of hair is a symptom of aging, but
