Why is there a deficiency of Vitamin D in the body? 8 reasons may be responsible for this.

News Topical, Digital Desk : Vitamin D deficiency has become a major problem today, with most Indians grappling with it. It causes symptoms like weakened immunity, weak bones, muscle pain, and depression. But have you ever wondered why Indians are so vitamin D deficient despite so much sunshine? 

Actually, there's no single factor responsible for this (Factors behind Vitamin D Deficiency). There are many factors that affect the levels of Vitamin D in our bodies. Let's explore the reasons behind Vitamin D deficiency.  

Reduce sun exposure

The best source of vitamin D is sunlight, but today's lifestyle often means people spend most of their time indoors, whether at home or in the office. Furthermore, wearing scarves, long-sleeved clothing, and excessive sunscreen to protect themselves from the sun also hinder vitamin D absorption. Increasing pollution also reduces outdoor exposure, which can lead to vitamin D deficiency. 

Vitamin D deficiency in the diet

Foods naturally rich in vitamin D are very limited. Fish like salmon, tuna, mackerel, eggs, cod liver oil, and some mushrooms naturally contain vitamin D. Some fortified foods, such as milk and orange juice, also contain vitamin D. A lack of these foods in the diet can also cause this problem. 

skin color

The melanin pigment in the skin affects the absorption of sunlight. Darker skin has more melanin, which protects against sunlight but also hinders the production of vitamin D. Therefore, people with darker skin need more sun exposure than those with lighter skin.

Effect of age

As we age, the body's ability to make vitamin D declines. Older people's skin becomes thinner, and the kidneys become less able to convert vitamin D into its active form. 

obesity

Vitamin D is a fat-soluble vitamin. Due to excess body fat, this vitamin is absorbed by fat cells. Therefore, obese individuals are at higher risk of vitamin D deficiency.

Medical conditions and medications

Certain health conditions affect the body's ability to absorb or convert vitamin D. These include celiac disease, Crohn's disease, cystic fibrosis, kidney or liver disease. Additionally, certain medications, such as anti-seizure medications, anti-fungals, and glucocorticoids, can also interfere with vitamin D metabolism.

Weather and geographical conditions

For those living in northern or southern regions far from the equator, the sun's rays are more oblique during the winter months. This weakens UV-B rays, which reduces vitamin D production. In India, too, vitamin D levels can drop due to weak sunlight during the winter season.

pregnancy and breast feeding

Pregnant and breastfeeding women have an increased need for vitamin D. If the mother is deficient in vitamin D, the baby may also be affected.
