Severe deficiency of vitamin D can cause rickets in children and osteomalacia, a similar disorder, in adults.
This due to deficient vitamin D levels resulting reduced calcium absorption, to only 10 to 15 percent of dietary calcium, and less than 50 percent absorption of dietary phosphorus. As a result, the protein scaffold made by osteoblasts can’t be mineralized.
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.
There was a hypothesis that vitamin D deficiency may increase the risk of prostate cancer, based on the finding that mortality rates of this cancer in the United States were inversely proportional to ultraviolet radiation.
Vitamin D deficiency has been linked to increased risk for cardiovascular disease, multiple sclerosis, rheumatoid arthritis and type 1 diabetes.
