The interrelationship of these glands is complex. An experienced health professional should be consulted to help improve the functioning of your hormone producing glands. Calcitonin opposes PTH, by promoting the transfer of calcium from the blood back into the bones. Thyroxin regulates the rate of body metabolism including that of bone metabolism. Either an over- or underactive thyroid can cause bone loss.
Stress can lead to thinning of the bones.
The adrenals also make many other hormones. They become a very important site for production of male and female sex hormones after menopause. At menopause, hormone production of estrogen and progesterone drop precipitously. They filter nearly 200 quarts of liquids daily, excreting waste materials and returning calcium, proteins and other substances to the blood. The kidneys are necessary for the production of vitamin D and together with the adrenals, for maintaining mineral balance.
