Vitamin D is an important nutrient that helps keep your health and well-being in check. Unfortunately, many people worldwide don’t get enough of it. This makes testing an important part of staying healthy.
Let’s discuss what Vitamin D is, its functions in the body, causes and symptoms of deficiency, groups at risk, and steps to get tested.
What is vitamin D, and how does it work in the body?
Vitamin D is a fat-soluble vitamin that helps the body absorb calcium and keep bones healthy. Vitamin D can be made by the skin when it is exposed to sunlight. It can also be found in some foods, such as mushrooms, eggs, salmon, and more.
Vitamin D is changed into an active form once the body takes it in. This helps control how much calcium and phosphorus are in the blood.
Causes of vitamin D deficiency
Vitamin D deficiency is common and can be caused by several things, such as:
- Lack of sun exposure
- Medical conditions
- Medications
- Poor dietary intake
- Age
You should note a combination of these factors increases the likelihood of developing vitamin D deficiency.
Symptoms of vitamin D deficiency
If you don’t get enough Vitamin D, you might have several symptoms that can affect your health and well-being. Some of the most common symptoms include:
- Fatigue and weakness: Vitamin D is essential for maintaining energy levels and combating fatigue, so a deficiency can leave you feeling tired and weak.
- Bone and muscle pain: Vitamin D helps the body absorb calcium, essential for maintaining strong bones. A deficiency can lead to weak bones and muscle pain, particularly in the legs, back, and hips.
- Depression: Vitamin D has been linked to mental health, and a deficiency has been associated with an increased risk of depression and other mood disorders.
- Impaired wound healing: Vitamin D is essential for the immune system and can help wounds heal more quickly. A deficiency can slow down the healing process.
- Hair loss: Vitamin D is important for maintaining healthy hair, and a deficiency can lead to hair thinning and loss.
- Autoimmune disorders: Vitamin D helps regulate the immune system, and a deficiency has been linked to an increased risk of autoimmune diseases, such as multiple sclerosis and rheumatoid arthritis.
These symptoms may be caused by other health problems and not directly by a lack of vitamin D. This is why it’s always best to consult a healthcare provider for a proper diagnosis.
Groups at risk of vitamin D deficiency
People with dark skin, elderly individuals, those who are overweight or obese, and those who have had gastric surgery are all at a higher risk of vitamin D deficiency.
Vitamin D testing
Two tests can be used to measure Vitamin D levels in the body: blood tests and saliva tests. Blood tests are the most common and are done by drawing a small blood sample from a vein in your arm. Saliva tests are a newer form of testing measuring vitamin D levels in saliva, and may involve an oral swab or spitting into a tube.
Before a vitamin D test, it is best to stay away from alcohol and dietary supplements for a few days. It’s also important to tell your doctor about any medications you’re taking since some can change your vitamin D levels.
The test results will tell you how much vitamin D is in your blood. Normal levels typically range between 20 ng/mL and 50 ng/mL, but can vary depending on a number of factors. A doctor can administer a vitamin D test. The results can help the doctor determine the appropriate course of action if vitamin D levels are low.
Final thoughts
Vitamin D plays a crucial role in maintaining overall health and well-being. With vitamin D deficiency being a common issue, knowing the symptoms and groups at risk is important. Vitamin D levels can be tested through a simple blood or saliva test. Early detection and treatment can help prevent further health complications and keep vitamin D levels normal.
