The Most Desirable Vitamin in Poland. This Is Why Your Breath Smells Bad

One of vitamin D's primary functions is regulating calcium and phosphorus metabolism, thus contributing to healthy bone formation in children and infants. Furthermore, vitamin D may prevent hypertension, heart disease, and diabetes. Vitamin D deficiency has also been linked to obesity, depression, and multiple sclerosis.

However, excess vitamin D is very rare. It most often occurs in people who suffer from vitamin D hypersensitivity and those who take excessive amounts of supplements over a long period of time.

Symptoms of excess vitamin D in the body

Vitamin D overdose is not possible through prolonged exposure to sunlight (our body inhibits excessive vitamin D production thanks to melanin) or by consuming products that are natural sources of the vitamin (vitamin D is found in very small amounts in food). Overdose only occurs through taking higher than recommended doses of dietary supplements or medications.

Symptoms of vitamin D overdose can be difficult to diagnose. The first sign may be that a person with hypervitaminosis D may experience constant weakness and fatigue.

Other symptoms include:

• biliousness,
• loss of appetite,
• itchy skin,
• excessive sweating,
• dehydration,
• tinnitus,
• enlargement of the liver and spleen,
• hyperactivity and irritability,
• metallic taste in the mouth,
• polyuria (increased urine output),
• polydipsia (excessive thirst and drinking large amounts of fluids during the day).

However, in infants and children, overdose may result in stunted growth.

What can a vitamin D overdose cause? Possible treatments

The dangerous effects of a vitamin D overdose include:

• hypercalciuria (increased urinary calcium excretion);
• Hypercalcemia (high blood calcium levels) can lead to calcium deposition in tissues, which can lead to heart and central nervous system disorders. Excessive urination, in turn, increases the risk of dehydration, while calcium deposition can lead to symptoms of kidney stones and kidney failure.

Another equally dangerous effect of vitamin D overdose may be, for example, calcification of blood vessels, the occurrence of heart rhythm disturbances and hypertension .

Vitamin D overdose requires first limiting calcium and phosphorus intake. If vitamin D levels are high, diuretics are used to support calcium excretion.

It may be necessary to administer corticosteroids or bisphosphates, and in extreme cases the doctor may decide to use hemodialysis.
