📖What is Vitamin D Deficiency?
Vitamin D deficiency occurs when the body has insufficient levels of vitamin D, a nutrient essential for calcium absorption, bone health, and immune function. Despite abundant sunshine, deficiency is remarkably widespread in India due to limited sun exposure from indoor lifestyles, skin pigmentation, and cultural clothing practices, along with low dietary intake of vitamin D-rich foods. The vitamin is synthesised in the skin upon sun exposure and also obtained from certain foods and supplements, and its deficiency affects nearly every system given vitamin D's role beyond just bone metabolism. Long-standing deficiency can lead to weakened bones, muscle pain, and increased fracture risk, and has also been linked to broader effects on immunity and mood. Diagnosis is made through a simple blood test, and correction with supplementation is generally straightforward and effective.
