Vitamin D deficiency
t has been known since about the 1990s that vitamin D occurrence extends to several organs and various tissues in humans. The essential function is the regulation and support of cell division in all areas of the body.
Vitamin D occurrence and diseases in the organism
The functions of the hormonal system and the immune system depend in part on the vitamin D supply.
An undersupply of the body with vitamin D has various consequences. A frequent symptom is long-term high blood pressure. Furthermore, there are numerous diseases of the cardiovascular system, which are related to the vitamin D occurrence. The metabolic syndrome also has a binding character.
By the metabolic syndrome, the medical profession understands an association of factors that form the risk factor for heart disease. These include a large accumulation of fat in the abdominal area, high blood pressure, elevated blood lipid levels and forms of diabetes. In the area of heart disease, vitamin D deficiency also increases the risk of posterior wall infarcts.
The risk of numerous other diseases is increased by a deficiency in vitamin D occurrence. These include allergies or diseases of the immune system. Diseases that are increasing in frequency, such as multiple sclerosis or Crohn’s disease, are more likely due to the weakening of the immune system.
Asthma in young adults and the elderly is also linked to vitamin D deficiency. Older individuals continue to be at increased risk for bone diseases such as osteoporosis and dementia. According to studies, the body’s decreased exercise and light intake in today’s society has contributed to the increase in dementia.
Vitamin D and diseases
These consequences must be distinguished from acute vitamin D deficiency. Here, myalgias and adynamia are the consequences. The former refers to symptomatic muscle pain. The latter refers to fatigue, which occurs predominantly in everyday life.
The prevention of vitamin D deficiency
Basically, the body of vertebrates, including humans, forms the majority of vitamin D deposits via the skin surface. Accordingly, the prerequisite is that the body receives sufficient sunlight.
The classic disease in the context of a vitamin D deficiency is rickets. This is a reduced formation of bones and bone marrow. To prevent this, the body needs exercise and sunlight.
According to studies, the risk of some cancers is also increased due to the lack of vitamin D. A diet with foods containing vitamin D supports the immune system and helps prevent serious diseases.
The predominant therapy is a treatment with artificial sunlight for a long period of time. To prepare for the dark season, sunny days should be used effectively. According to medical specialists, exposure of about 20-30% of the body for a few minutes is sufficient. For this, this must be done regularly.
Storage of the vitamin D supply
Once vitamin D has been absorbed, the human body stores it for several months. In the diet, vitamin D is predominantly present in fatty fish. These include salmon and mackerel, for example. In addition, physicians advise taking dietary supplements that contain vitamin D. The dosage is important, because too large a dose also increases the calcium content in the blood.
To date, it has not been fully researched whether these supplements can actually replace the intake of vitamin D from sunlight. Accordingly, the body should still get regular sunlight. In solariums, the body receives artificial sunlight, but almost exclusively UVA radiation. This tans the skin, but is not necessary for the metabolism of vitamin D.
Vitamin D properties
Vitamin D occurrence does not actually denote a vitamin by definition. Rather, there are different types of vitamin D. It is a hormone that performs tasks as a prohormone. A normal vitamin D occurrence has several positive effects on the human body.
For one, studies show that the risk of asthmatic diseases and diabetes is lower. On the other hand, an increased vitamin D occurrence helps against periodontal disease. Scientists also see links between psychiatric diseases such as schizophrenia and depression.
The vitamin D occurrence and the supply with this hormone has an important role in the body. The extensive consequences of a deficiency have not yet been fully clarified. On the contrary, studies show that the intake of vitamin D weakens the course of many diseases. These also include long-term diseases. Sunlight and a healthy diet with foods containing vitamins support the immune system and also sustainably increase the vitamin D supply.
