E67.3: Hypervitaminosis D

You have been found to have an increased vitamin D value.

Vitamin D is important for bone hardness, for example. Calcium and phosphate are stored in the bones by vitamin D. Bone thus hardens. Vitamin D moreover has effects on the intestines, skin or blood cells.

The body can create vitamin D itself. Sunlight is required for that. The intestines, liver and kidneys are involved in creating vitamin D. You can also take vitamin D with food. However, this normally only makes up a small part of your body’s vitamin D. It is also possible to take vitamin D as a food supplement.

The vitamin D value can be increased if you take too much vitamin D as a food supplement. The vitamin D value can also be increased by a treatment with vitamin D.

Various symptoms may develop due to too much vitamin D in the body. For example, you may often be tired or feel an urge to vomit. Furthermore, the calcium value in the blood may increase as a result. The excess calcium may impair the work of the kidneys, among other things. As a result, you may have to pass more urine than usual. Excess calcium may also be deposited at various sites in the body, for example in the kidneys or blood vessels. That may cause permanent damage to the kidneys or result in high blood pressure.
