Symptoms & Diseases Associated With Vitamin D Deficiency
Frank LipmanSeptember 15
It is estimated that anywhere from 30 to 100% of Americans, depending upon their age and community living environments, are deficient in Vitamin D. More than half of all American children are vitamin deficient. Supposedly almost 3/4s of pregnant women are vitamin D deficient, predisposing their unborn children to all sorts of problems. Worldwide, it is estimated that the epidemic of vitamin D deficiency affects one billion people. In my practice over 80% of patients whose vitamin D levels I check are deficient.
No one is exactly sure why this is happening apart from the fact that we spend too much time indoors and when we go out into the sun, we lather sunscreen on ourselves. I think it must be more than that. But whatever the reason, the reality is we have a major epidemic on our hands.
How much vitamin D do I need?
How much vitamin D you need varies with age, body weight, percent of body fat, latitude, skin coloration, season of the year, use of sun block, individual variation in sun exposure, and – probably – how ill you are.
As a general rule, old people need more than young people, big people need more that little people, fat people need more than skinny people, northern people need more than southern people, dark-skinned people need more than fair skinned people, winter people need more than summer people, sun block lovers need more than sun block haters, sun-phobes need more than sun worshipers, and ill people may need more than well people.
What I and many of my colleagues around the country are finding is that even people spending what we thought was adequate amount of time in the sun, are still showing up with low blood vitamin D levels. I am not sure why at this stage but there is an easy and cheap solution…vitamin D supplementation.
Here are some guidelines:
What are the symptoms of vit D deficiency?
There is no clear pattern of symptoms. In fact many people remain asymptomatic despite low levels. But here are the more common symptoms
What diseases are associated with Vit D deficiency?
Vitamin D deficiency has been shown to play a role in almost every major disease. This includes:
What about vitamin D toxicity?
It is impossible to generate too much vitamin D in your body from sunlight exposure: your body will self-regulate and only generate what it needs. Although very rare, it is possible to overdose and become toxic with supplementation as vitamin D is a fat soluble vitamin and therefore stored in the body for longer periods of time. Therefore if you are taking 5,000 IU or more daily, you should have your blood levels monitored approximately every 3 months.
What blood test should I have to check my vitamin D levels?
The only blood test that can diagnose vitamin D deficiency is a 25-hydroxy-vitamin D (25 OH vitamin D). Unfortunately, some doctors are still ordering the wrong test, 1,25-dihydroxy-vitamin D. In fact a common cause of high 1,25-dihydroxy-vitamin D is a low 25(OH)D or vitamin D deficiency. So when doctors see the 1,25-dihydroxy-vitamin D is normal or high and tell their patients that they are OK, they are often vitamin D deficient.
Your doctor should do this test for you. Unfortunately even some of the labs, in particular Qwest, have had problems with correct results, usually giving erroneously high results.
If you don’t want to go through your doctor, the ZRT lab does a blood spot test that you can order without going through a doctor.
What is the ideal blood level of 25 hydroxy vitamin D?
The current ranges for “normal” are 20 to 55 ng/ml. These are much too low!!! They may be fine if you want to prevent rickets or osteomalacia, but not for optimal health. The ideal range for optimal health is 50-80 ng/ml.
How often should I have a 25 hydroxy vitamin D blood test?
At least once a year especially at the beginning of winter. If you are supplementing, I suggest you monitor your vitamin D levels approximately every 3months until you are in the optimal range. If you are taking high doses (10,000 IU a day) your doctor must also check your calcium, phosphorous, and parathyroid hormone levels every 3 months.
