How Hormones Regulate Calcium

The human body contains more than 2.2 pounds of calcium, mostly in the bones. As most people know, calcium is vital for human health. 

In fact, it is such an important mineral that our bodies are designed to use various hormones to ensure adequate calcium levels in both the bloodstream and the bones. 

The hormones responsible for maintaining calcium levels include vitamin D, calcitonin, and parathyroid hormone. 

Specifically, vitamin D enhances absorption of calcium from the gastrointestinal tract; calcitonin stimulates the absorption of calcium into bones; and parathyroid hormone causes calcium to be released by the bones. 

The complex interplay between these three hormones are responsible for ensuring: 

• Adequate calcium absorption

• Integration of calcium into the bones

• Normal serum calcium levels

Parathyroid hormone — which is secreted by the parathyroid glands — increases the concentration of calcium in the bloodstream by releasing calcium from the bones. This process is called “bone resorption.” 

In the kidneys, parathyroid increases reabsorption of calcium. In other words, it decreases calcium excretion in the urine. 

Hyperparathyroidism — an excess of parathyroid hormone — is known to cause both osteopenia and osteoporosis. In treating osteoporosis, it is important to closely monitor parathyroid hormone levels. 

It should be supplemented only when levels are very low.

Vitamin Supplements

This article appeared in the first Johns Hopkins Health Review  

“Save your money—and possibly your good health—by skipping the vitamin supplements. Study after study has shown that taking vitamins won’t stave off chronic diseases or untimely death. So from a medicinal perspective, there is no reason for well-fed people to take them, according to researchers at Johns Hopkins and several other institutions. It’s not just that the experts have deemed vitamins useless: They’ve also determined that taking bonus beta-carotene, vitamin E, and vitamin A may contribute to a heightened risk of death. For many lifetime vitamin poppers, this news is hard to swallow. After all, mom doled out that chalky, vaguely fruity multivitamin tablet every morning as part of a nutritious breakfast. It’s time to cast sentimentality aside because the facts show that vitamins are not a magic bullet, even though they might be shaped like one.” http://www.johnshopkinshealthreview.com/_docs/JHHR_Fall_2104.pdf 

So what is well fed, good life style?  The “Garden of Eden” would be a great choice – full body sunshine, nothing but greens and citrus, and no stress.  Since we are not in Eden, consider taking 1000-2000 units of vitamin D3 daily (full body sunshine), 1mg (1000 ug) Folic Acid (vegetarian diet), 500 unit of vitamin C (citrus), and sublingual B12 only if it is low (compensation for stress).  A normal diet contains more than enough calcium, making calcium tablets useless, possibly increasing risks for kidney stones.   

I check levels of vitamin D, Vitamin B12 and Vitamin B9 (Folic Acid) in most of my patients and more often than not the vitamin D level is low and the Folate level is low normal.  B12 varies and often is at a low normal level.  So, without checking to see if you need any vitamins at all, consider supplementing D3, C, Folate, and B12.

Menopause Myths Debunked!

Menopause Myth #1: Going through menopause is horrible

Perimenopause, the years leading up to menopause can be a time of biochemical chaos in the body as your estrogen, progesterone and testosterone levels work to establish balance, and  fertility begins to decline and finally ceases altogether. During this period, women can experience things like:

  • Hot flashes 
  • Lowered libido
  • Unusual mood swings or depression
  • Weight that goes on easy and is hard to get rid of
  • Lower energy levels

That may sound ghastly at first, but keep in mind that women rarely experience all of the above. Most experience one or two and they occur gradually over time, at varying degrees of inconvenience. In fact, only about 40% of women say they experienced significant symptoms of menopause, and most of them only experienced symptoms for a brief span of time. That means the majority of women never have anything more than mild symptoms.

Menopause Myth #2: Menopause symptoms never stop

It is very rare that menopause symptoms don't disappear or significantly retreat once menopause has been reached. While most of those hot flashes occur very sporadically. If your doctor has determined you have reached menopause (when you have ceased menstruating for 12 months in a row) and you are still experiencing menopause symptoms, it is a sign that your hormones are out of balance. Have them tested by using MedAmiLabs today to find out a treatment option.

Menopause Myth #3: Menopause means the end of your sex life

The hormone shifts that occur during menopause can cause a decrease in your natural lubrication and a thinning of the vaginal tissues. However, this is rarely enough to ruin a woman's sex life. And, in fact, many women report that their post-menopausal sex life is better than ever because they no longer need birth control, they are more comfortable with their bodies, financial worries and other stresses have diminished and the kids are out of the house (or will be soon!), which means you are no longer worried about privacy. Most of the post-menopausal changes that affect libido, or your physical comfort, can be addressed using over-the-counter lubricants, position changes or mild natural hormone therapy.

Don't fall prey to scary menopause myths. Instead, talk openly and honestly with a trusted healthcare professional regarding your fears, symptoms and concerns. Better yet, consult with our office and use accurate hormone testing to determine whether or not you would benefit from the bioidentical hormone therapy that can stop those dreaded hot flashes after menopause.

The more educated and informed you are, the more empowered you will be to embrace this new phase in your life.
