Vitamin D deficiency is a common condition affecting a large number of people. Vitamin D is important in maintaining bone health. Its deficiency leads to bone marrow and contributes to fractures caused by fragility. Vitamin D deficiency is associated with a wide range of conditions related to In the skeleton, vitamin D can be readily determined in patients by serum 25-hydroxyvitamin, and vitamin D intake should be prescribed to the patient. The amount taken is dependent on the severity of the deficiency. Exposure to toxicity due to vitamin D intake is unlikely.
In the Middle East, it is known that sunlight is available, so it may be surprising that vitamin D deficiency is a common condition affecting a large proportion of the Orientals. The result that usually shows vitamin D deficiency is bone marrow, which contributes to osteoporosis, This is what we meant earlier by saying fractures of fragility, in part by increasing the risk of vitamin D deficiency as in other cases including cardiovascular disease, increased risk of cancer and death, diabetes, multiple sclerosis, arthritis, epilepsy and cognitive impairment.
Vitamin D: The main forms are vitamin D3 (colicciferol) and vitamin D2 (ergocalciferol). These are transferred to the liver and are represented to 25 hydroxyvitamin D3 and 25 hydroxy vitamin D2, which are the main forms of vitamin D and are measured in most measurements, The second is produced in the kidneys to form D25 1.25 dihydroxy, also known as calcitriol, and 1.25 dihydroxy D2, these are the forms of vitamin D activation – any forms that the body utilizes and absorbs. It has three main functions:.
1. Enhance the absorption of calcium and phosphate from the small intestine.
2. Inhibiting the manufacture and secretion of thyroid hormone.
3. It is also related to minerals found in bones.
The results do not show that the weakness in renal function with a decrease in production of 1.25 dihydroxyd, has a significant effect on vitamin D metabolism.
Sources of vitamin D: The main source of vitamin D comes from the exposure of the skin to the sun, so there is a significant seasonal difference with higher concentrations at the end of the summer compared with other seasons, and there is vitamin D3 in fatty fish such as herring, salmon and mackerel, found in other sources eggs, meat and fortified foods such as vegetable margarine .
