Date November 19, 2019 18:04

Vitamin D deficiency may go unnoticed if it’s mild, but if your vitamin D levels have been too low over a period of time, you can start to experience unpleasant symptoms such as fatigue, bone and muscle pain.

Vitamin D is the only vitamin your body can produce on its own. Exposure to sunlight stimulates the production of this vitamin in your body. But you can also get it from certain foods or supplements. This vitamin helps to support bone health. It’s also important to have enough vitamin D to keep your muscles, nerves, and the immune system healthy.

Vitamin D deficiency is very common: 1 billion people around the world may be deficient, according to some estimates.

Vitamin D deficiency: who is at risk

The causes of vitamin D deficiency can be different. Certain groups of people are more likely than others to develop vitamin D deficiency. They include:

  • babies who are fed exclusively with breast milk for prolonged periods of time;
  • people who live in areas where there’s not enough sunlight;
  • elderly people;
  • people with dark skin;
  • overweight and obese people;
  • people with liver disease or kidney disease
  • people with Crohn’s disease, celiac disease, and other conditions that affect the absorption of vitamin D and other nutrients;
  • people who take medicines that interfere with the metabolism of vitamin D, such as anticonvulsants and glucocorticoids.

If you are at an increased risk of vitamin D deficiency, your doctor will likely recommend a supplement.

Symptoms of vitamin D deficiency

If your deficiency is mild, you will not have symptoms, or they will be hardly noticeable. But if your deficiency is more serious, you may have the following signs and symptoms:

Frequent infections

Having enough vitamin D is essential for your immune system, and if you’re deficient, you may get colds and other infections more often.

Tiredness

You can feel constantly tired for many reasons, including vitamin D deficiency. If your doctor suspects that’s the case, he or she will order a blood test to measure your levels of vitamin D.

Bone and muscle pain

Vitamin D is vital for your muscles and bones, and if you don’t have enough of it, your bones and muscles may hurt.

The connection between low levels of vitamin D and depressed mood isn’t exactly clear, but some studies suggest that taking a supplement may improve depression, according to HealthLine.

How to get more vitamin D?

Lack of vitamin D in your body can contribute to serious health problems, such as osteoporosis and cardiovascular disease. Fortunately, the problem can be treated or prevented by getting more vitamin D from diet changes and being in the sun. Being outside in the sun when it’s the least active can help stimulate vitamin D production in your body, but it’s important to keep in mind that excessive sunlight exposure is harmful.
