The amount of Growth Hormone (GH) we have in our bodies changes with age, and also can shift at various times during the day. Nutrition, exercise, sleep and stress also have an impact on our GH levels. GH plays a critical role in our metabolism and the health of our body tissue throughout our lives, and fuels our growth when we are children and young adults. Consequently, it is critical that we maintain adequate levels of GH, and not allow ourselves to become growth hormone deficient as we age. In some cases, patients may elect to elevate their growth hormone through Virility, Inc’s Growth Hormone Optimization protocols.
How is HG Measured?
Human Growth may be assessed and measured by blood tests. Because GH levels change from day to day and at different times during a 24-hour cycle, many physicians may find it necessary to take more than one blood sample, and do so on different days. A type of GH, known as insulin-like Growth Factor 1 (IGF-1) is tested separately. IGF-1 levels generally do not fluctuate as rapidly.
Aging and GH
Two glands located in the human brain – the pituitary and hypothalamus – are the main actors in the creation and continued production of growth hormone. The pituitary gland, which produces growth hormone, secretes the highest levels of GH during puberty. The continued production of GH is controlled by various hormones produced by the hypothalamus, and to a lesser degree in the pancreas and intestinal tract. The rate of GH production declines steadily after puberty. A number of physiological changes contribute to this decline, including a decrease in the serum levels of IGF-1. A decline in the production in the hypothalamus of hormones that stimulate GH production also plays a role in the reduction of growth hormone in our bodies as we age.
