Vitamin D Deficiency

Vitamin D is unique because we not only get it from food, but also the sun! Also known as the “sunshine vitamin,” it is essential for strong bones and preventing diseases like rickets, osteopenia, and osteoporosis. Exposure to sunlight and a proper diet will often prevent Vitamin D deficiency, but not always.

In many cases, there are no symptoms to reveal that Vitamin D deficiency exists.   However, in some situations, symptoms may include:

  • Depression
  • Fatigue
  • Muscle weakness or twitching
  • Muscle or bone pain
  • Thin and brittle bones

While symptoms may be vague, prolonged Vitamin D deficiency can lead to other conditions like hyperparathyroidism.  In the older population, it can also lead to symptoms of osteoporosis like fragile-bone fractures.


There are several causes of Vitamin D deficiency.   The most common causes include:

  • Abnormal bowel conditions (i.e. inflammatory bowel disease)
  • Chronic liver, kidney, or pancreatic disease
  • Decreased sun exposure
  • Dietary diseases (i.e. celiac disease)
  • Insufficient diet
  • Some medications

In any situation, when the body is not able to absorb or properly use Vitamin D, it may be in a state of deficiency.

Risk Factors

The most common risk factors to Vitamin D deficiency include:

  • Age
  • Chronic liver, kidney, or pancreatic disease
  • Dark skin
  • Indoor lifestyle 
  • Strict vegan diet
  • Obesity

Understanding the risk factors will provide insight into prevention and treatment plans.  While some risk factors, like aging or skin color, cannot be controlled, some can be managed with lifestyle adjustments.


The most common way to diagnose Vitamin D deficiency is with a blood test.  Blood tests accurately measure the levels of Vitamin D in the blood.  In some cases, an x-ray or bone-density scan may be ordered in situations when bone strength is in question.   Our providers can review your health history and, with one or more of these tests, accurately diagnose Vitamin D deficiency.

Of course, treatments will vary based on the unique condition of the individual.  However, the most common treatment is prescribing Vitamin D supplements.  Other supplements, like calcium and phosphate, may be considered.

The most effective treatment of Vitamin D deficiency is prevention.  Lifestyles that include sun exposure and a healthy diet of Vitamin D rich foods like fish, eggs, milk, and other animal-based foods, will help prevent the deficiency.

In other situations, like that of a chronic disease, proper treatment of the condition along with supplements will be necessary.
