10 interesting Vitamin D deficiency causes
Some interesting Vitamin D Deficiency causes are coming to light as increasing research reveals just how valuable Vitamin D is to our health.
Sun rising for Vitamin D
Vitamin D is not known internationally as "the sunshine vitamin" without reason. The lack of sufficient exposure to the sun's UVB rays is more readily accepted globally now as research looks into so many ways the sun and Vitamin D are able to improve people's health issues, from relatively mild health disorders to serious life threatening ones.
Discovering whether you are Vit D deficient has therefore become a lot more serious in the medical world. But it's not all as easy as that and is in fact quite complex, as there are so many possible causes.
Extracted from a report by health organizations in the UK, I have chosen 10 interesting points to highlight about vitamin D deficiency causes.

UK Joint statement on Vitamin D deficiency causes
A statement was issued jointly by the following organizations in the UK on Vitamin D deficiency causes:
This substantial statement is remarkable in itself in that this collection of reputable health organizations has acknowledged the importance of stating publicly how vital Vitamin D is for human health.
The fact that they may be criticized by many for being too conservative is countered by the fact that there was comparative silence from their counterparts elsewhere in the world.
The following are 10 items I found most interesting in this report.
Top 10 vitamin D deficiency causes:
Staying indoors a cause for Vit D deficiency
- The report states that "the best way to obtain your vitamin D is by UVB sunlight falling on unexposed skin in doses that do not cause sunburn". The reverse of this implies no sunlight on your skin will cause a deficiency.
- Darker skinned people require a much longer time in the sun for their skin to absorb Vitamin D. Without this extended exposure a deficiency may be caused.
- Obesity may cause a deficiency by Vitamin D being absorbed by the fat tissue and not allowing uptake into the blood stream.
- As we get older, our ability to absorb Vitamin D becomes impaired. Thus the elderly are more at risk for a deficiency in Vitamin D and perhaps explains to me why they tend to love sitting in the sun as often as possible?
- People who wear whole-body covering clothing everyday and thus have extremely limited exposure to the sun are likely to be Vitamin D deficient.
- Infants born to Vitamin D deficient mothers are at risk of being deficient in Vitamin D, especially if they are exclusively breast fed as they are not likely to obtain any Vitamin D at all through their mother's milk.
- Health institutions that deny anyone access to the sun, are likely to cause a deficiency of Vitamin D in their patients and thereby compromise a healthy recovery.
- Personal sun intolerance conditions that cause a person to avoid the sun will also likely cause a Vitamin D deficiency. A catch 22 surely?
- Living in a geographical area where sunlight is limited or even zero in some months, without any dietary supplements containing Vitamin D or even sun-bed usage, will surely result in a Vitamin D deficiency.
- Lastly, overuse of sunscreen, to the extent that exposure to the sun is seriously limited, will more than likely result in a Vitamin D deficiency. Careful balance is required here - just enough UVB exposure without getting sun burnt.
What level is defined as Vitamin D deficient?
The same UK based joint statement believes "there is currently no standard definition of an 'optimal' level of Vit D. The consensus is that levels of 25(OH)D below 25 nmol/L indicate deficiency. Many have argued that this level is far too conservative". Raising the levels of 'deficiency' or "sufficiency" will depend on the outcome of future research they say.
There is even a case reported whereby a 12-year-old girl called Tyler Attrill, diagnosed with the vitamin D deficiency disease Rickets, was told that her condition could have been caused by using an SPF 50 sunscreen for most of her life and depriving her of the essential vitamin and ultimately causing the bone disease.
See the BBC's video report about this: Sun cream caused vitamin D deficiency'
So, the bottom line is that sunlight exposure is good for you and that people should seek to expose themselves to the sun's UVB rays, without sunscreen, in order to produce more vitamin D. Just don't overdo it and get sun burnt!
Statistics of USA Vitamin D deficiency causes
Statistics for Vitamin D deficiency causes in the USA revealed some interesting results, (although how the statistics were obtained is always another interesting aspect):
- 32% of doctors and medical school students are Vitamin D deficient.
- 40% of the U.S.A population is Vitamin D deficient.
- 42% of African American women of childbearing age are deficient in Vitamin D.
- 48% of young girls (9-11 years old) are Vitamin D deficient.
- Up to 60% of all hospital patients are Vitamin D deficient.
- 76% of pregnant mothers are severely Vitamin D deficient, causing widespread vitamin D deficiencies in their unborn children, which predisposes them to type 1 diabetes, arthritis, multiple sclerosis and schizophrenia later in life. 81% of the children born to these mothers were deficient.
- Up to 80% of nursing home patients are Vitamin D deficient.
