Symptoms of vitamin D deficiency

The major source of vitamin D for humans is exposure to sunlight. Anything that diminishes the transmission of solar UVB radiation to the earth’s surface or anything that interferes with the penetration of UVB radiation into the skin will affect the cutaneous synthesis of vitamin D3.

Very few foods naturally contain vitamin D, and foods that are fortified with vitamin D are often inadequate to satisfy either a child’s or an adult’s vitamin D requirement.

Symptoms that point to vitamin D deficiency are muscle spasms, bone pain and joint pain. Lesser degrees of deficiency may be characterized by loss of appetite, a burning sensation in the mouth and throat, diarrhea, insomnia, visual problems, and weight loss.

Vitamin D deficiency causes bone to demineralize. In children, vitamin D deficiency causes rickets, a disease in which the bones become soft, weak, deformed, and painful.

Adults with osteomalacia may experience global bone discomfort and muscle aches, often leading to a misdiagnosis of fibromyalgia, chronic fatigue syndrome, or arthritis.

Long-term shortages of vitamin D and calcium cause human bones to become fragile and break more easily. This condition is called osteoporosis.
