Vitamin D deficiency can cause a range of symptoms, including fatigue, muscle weakness, bone pain, and an increased risk of fractures. Vitamin D deficiency can also cause depression, difficulty concentrating, and a weakened immune system. Long-term vitamin D deficiency can lead to osteoporosis, a condition in which the bones become weak and fragile.
Other signs and symptoms of vitamin D deficiency include bone and joint pain, bone deformities, an increased risk of infections, and an increased risk of autoimmune diseases. Vitamin D deficiency can also lead to changes in the skin, such as dark patches, and hair loss. Severe vitamin D deficiency can lead to rickets, a condition in which the bones become soft and weaken.
It is important to note that some people with vitamin D deficiency may have no symptoms at all. This is why it is important to get your vitamin D levels checked if you are concerned about a possible deficiency.
