What is human growth hormone?
Human growth hormone (hGH) is a signaling protein with a specific shape, comprised of 191 amino acids in a unique sequence. Secreted by pituitary, immune, fat and bone cells, hGH promotes growth, regulates the heart and metabolism, and coordinates psychological and physical health. HGH levels decrease significantly with age.
What organs respond best to hGH?
HGH predictably affects the liver, intestines, skin, Islets of Langerhans, prostate and uterus (hormonal). Additionally, hGH targets the heart, brain, eyes, and specific immune cells (nervous and immune). All of these organs decline in health during the aging process. Organs actually shrink in size during the aging process. It is well documented that hGH stimulates organs to return to their original, youthful sizes.
What happens to hGH levels as people age Health Questions?
The presence of hGH in a healthy adult declines at a rate of about 14% per decade after age 30 and is frequently non-existent by age 80. The American Association of Endocrinology and the American College of Endocrinology suggest that growth hormone deficiency is an age-related event characteristically defined as a cluster of easy to recognize symptoms that include:
Increased weight and abdominal obesity
Decreased lean body mass, muscle mass, and strength
Decreased exercise capacity and physical performance
Impaired sense of well-being
Emotional instability, anxiety
