What is Vitamin D Deficiency?
Vitamin D is a vital nutrient that helps your body absorb calcium. It keeps your bones, teeth, and muscles healthy. When you do not get enough vitamin D, you may develop a condition called vitamin D deficiency. This can lead to weak bones and other health problems. Many people do not realize they have low vitamin D until symptoms appear. According to the World Health Organization (WHO), vitamin D deficiency is common worldwide.
Why is Vitamin D Deficiency Common in Winter?
During winter, vitamin D deficiency becomes more common. This is because your skin makes vitamin D when exposed to sunlight. However, in winter, days are shorter and the sun is weaker. People also spend more time indoors. In some regions, especially those far from the equator, sunlight is very limited. As a result, your body may not make enough vitamin D. Additionally, heavy clothing and cloudy weather can block sunlight. For these reasons, vitamin D deficiency in winter is a growing concern.
Common Symptoms of Vitamin D Deficiency
Vitamin D deficiency can cause many symptoms. Some people may not notice any signs at first. However, as the deficiency worsens, you may experience:
For example, children with low vitamin D may have bone problems like rickets. Adults may develop soft bones, a condition called osteomalacia. If you notice these symptoms of low vitamin D, it is important to seek help.
Diagnostic Tests for Vitamin D Deficiency
If you suspect vitamin D deficiency in winter, your doctor may suggest a test. The most common way to check is with a vitamin D blood test. This test measures the level of 25-hydroxyvitamin D in your blood. Here are the main steps:
According to the Centers for Disease Control and Prevention (CDC), a normal level is usually above 20 nanograms per milliliter (ng/mL). Levels below this may mean you have a deficiency. If you want to know how to test for vitamin D deficiency, ask your healthcare provider about the vitamin D blood test.
When to See a Doctor
