Vitamin D deficiency can have various signs and symptoms, but it's important to note that many people with a deficiency may not exhibit any noticeable symptoms until the deficiency becomes severe. Some common signs and symptoms of vitamin D deficiency include:
Feeling excessively tired or fatigued is a common symptom of vitamin D deficiency.
Vitamin D plays a crucial role in maintaining healthy bones and muscles. Deficiency can lead to muscle aches, weakness, and bone pain.
Vitamin D plays a role in the immune system. A deficiency may result in more frequent infections or longer recovery times from illnesses.
In some cases, hair loss or excessive hair shedding may be associated with vitamin D deficiency.
Some studies suggest a link between low vitamin D levels and mood disorders such as depression and seasonal affective disorder (SAD).
Vitamin D deficiency can contribute to dental problems, including gum disease and tooth decay.
Deficiency can lead to a softening of the bones, which can cause bone pain and increase the risk of fractures.
Joint pain, particularly in the knees and hips, can be associated with a deficiency.
Some individuals with low vitamin D levels may experience sleep disturbances, such as difficulty falling asleep or staying asleep.
A decreased appetite can be associated with vitamin D deficiency, which can lead to unintended weight loss in some cases.
