Deficiency of vitamin D
Severe deficiency of vitamin D can cause rickets on children and osteomalacia, a similar disorder, in adults.
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.
In one study, there are indications that vitamin D deficiency is much more wide spread than previous thought, especially in older adults.
In a group of people of whom few had risk factors of vitamin D deficiency, 57 percent were found to have below normal levels of vitamin D.
Sixty seven percent of those reporting a vitamin D intake below the RDI had deficiencies categories as moderate to severe.
