CHANGES WITH AGING: ENDOCRINE SYSTEM
The endocrine system consists of several glands and
organs that produce hormones, which act as messengers
to help regulate and coordinate activities throughout
the body. The levels and activity of some hormones decrease
with age. In particular, the level of HGH,
the growth hormone decreases, causing a decrease in
muscle mass. The level of aldosterone, a hormone produced
by the adrenal glands, also decreases contributing to
the tendency of older people to become dehydrated more
Most hormonal changes do not affect how the body functions.
However, during certain circumstances, the body's functions
may be affected. For example, the pancreas is not as
effective in managing insulin levels, especially after
large meals. This change may have no noticeable effect,
but can be an early warning of diabetes.
- Ages 25 to 35 - Most hormone levels
start to decrease. Growth
Hormone [HGH] level falls approximately 14% by
Ages 35 to 45 - By age 45, production
of many hormones has fallen by more than 25%, and
biomarkers are beginning to show signs of aging.
- Ages 45 and Above - Most hormone
production continues to decline, including DHEA, Melatonin,
Hormone[HGH], and male and female sexual hormones.
The rate of decline accelerates as we get older until
around age 70.
Growth Hormone supplements are seen by many as a
way to counter the bodies own natural decline. Some
products attempt to replace the hormone itself, whilst
most act as pre-cursors to stimulate the bodies own
production of HGH.
