Vitamin D Deficiency: Cause, Symptoms, and Treatment post thumbnail image

Vitamin D Deficiency can cause many disorders in the body. Vitamins are the types of nutrients (others are protein, fat, carbohydrate, minerals, etc.) that our body requires to grow and develop normally.

There are several vitamins required in the body like vitamins a, b, c, d, e k, etc. Out of these, Vitamin D can be produced by the human body in the presence of sunlight. Vitamin D can also be taken from certain food items included in the diet.

Vitamin D is a fat-soluble vitamin that is also known as “calciferol” and is present naturally in some foods and available as a dietary supplement.

Vitamin D actually is not a true vitamin but a prohormone (a precursor of a hormone) as our body can produce it like other hormones. It is produced in your skin as a response to sun exposure, that is why sometimes it is called a “sunshine vitamin”.

Deficiency of vitamin D

Although your body can create Vitamin D, many factors can cause the deficiency of Vitamin D in the body, which includes –

  • Use of Sunscreen: Any sunscreen with an SPF (sun protection factor) of 30 or above reduces the ability of the body to synthesize the vitamin D naturally.
  • Covering your body: If you are covering the skin with clothing, it can also inhibit vitamin D production in the body.
  • Living indoors: If you are spending more time indoors like in home, offices, school, etc., chances of vitamin d deficiency increase.
  • Livening in high polluted Areas: People living in areas of high pollution or who work in night shifts are more prone to vitamin D deficiency.
  • Obesity: Obese persons having BMI (body mass index) greater than 30 are more likely to have vitamin D deficiency. Fat cells prevent the release of vitamin D by isolating it.
  • Skin type: Darker skin has a high level of melanin (skin pigmentation). The higher the level of melanin, the less vitamin D the skin can absorb. Sunlight absorption through the skin is essential to produce vitamin D in a healthy body.
  • Some medical conditions: A few diseases like Crohn’s disease, Cystic fibrosis, and celiac disease, cause a problem in the absorption of Vitamin D through the intestines which result in deficiency of Vitamin D.

Due to the above factors vitamin D deficiency is increasing nowadays in most people. You can take Vitamin D supplements, but natural sources are best and it’s free of course.
