Vitamin D deficiency can be deadly: study with shocking results

  • Vitamin D deficiency can serious health consequences to get
  • Study shows: deficiency perhaps premature death carry out
  • One group of people is particularly at risk

Too little sun, almost no time outdoors: Especially in the winter months, the vitamin D level in many people drops dramatically. Because the body’s production of vitamin D is only triggered by direct sunlight. However, when it is cold, many people leave their homes less often, which can be an additional risk factor for vitamin D deficiency if there are fewer hours of sunshine. A vitamin D level that is too low is often underestimated or even overlooked. However, a study from the Medical University of Vienna reveals how dangerous a deficiency can be.

Vitamin D deficiency: early death possible under certain circumstances

However, it should first be mentioned that the Vitamin D supplementation can never do everything. A research team from Massachusetts General Hospitals Harvard Medical School found that vitamin D supplementation had no effect on a person’s susceptibility to depressions is or not. Contrary to what you initially thought. The team refuted a common misconception.

To that end, around 18,000 middle-aged men were observed over a five-year period in the most extensive study on this subject to date. The results were published in the journal JAMA and allow clear conclusions to be drawn about what Prevention of depression with vitamin D concerns.

Vitamin D occupies a special position among all vitamins: it can not only be ingested through food, but is also produced by the body itself – mainly through the absorption of sunlight. the pure intake through food often not enough to meet the body’s vitamin D needs.

Vitamin D deficiency and increased mortality: their link

What consequences a Vitamin D deficiency was examined by Austrian scientists – the results of the study are worrying. Scientists from the University of Vienna have analyzed whether there is a link between vitamin D deficiency in the body and increased mortality. They presented their results at the annual conference of the “European Association for the Study of Diabetes”.

The study came to the following conclusions: Increased mortality and vitamin D deficiency go hand in hand close the connection. Parallels could be found especially in young and middle-aged people. It is also alarming that vitamin D deficiency has been associated in particular with deaths from diabetes.

The link between increased mortality and vitamin D deficiency has already been proven in numerous studies. However, much of the research can be attributed to the study of older test subjects. Here, an influence on the results by an increased rate of vitamin D supplementation cannot be excluded.

Vienna study on vitamin D deficiency

At the Department of Laboratory Medicine Vienna General Hospital measurements were taken between 1991 and 2011 on a total of 78,581 patients (31.5% male, mean age 51 years). Vitamin D content in the body executed. Researchers in the new study used data from the records and compared it with Austria death register. Where possible, patients were followed for up to 20 years (mean duration was 10.5 years).

The mean value of the vitamin D blood level was 50 nmol/l (nanomoles per litre). This value could then be compared to a low blood level (10 nmol/l) and a high blood level (90 nmol/l) of vitamin D.

It is apparent from these observations that low levels of vitamin D in the blood associated with a two to three times increased risk of death became. The greatest effect (2.9-fold increased risk) was observed in patients aged 45-60 years. It dropped up to 40% all-cause mortalitywhen a vitamin D blood levels of 90 nmol/l was present. Here, too, the greatest effect was seen in test subjects between the ages of 45 and 60. Only in patients over the age of 75 did high vitamin D blood levels not result in a statistically significant link.

Vitamin D deficiency increases the risk of death: diabetics are particularly affected

Part of the study also looked at the links between vitamin D and various diseases. For this purpose, the mortality values ​​by cause, i.e. the number of death due to a specific disease in relation to the size of the population, in relation to the blood content. Surprisingly, the biggest connection here is not between cardiovascular illnesses or Cancer.

A completely different disease has reacted particularly intensely to vitamin D deficiency: diabetic patients. diabetic those in the vitamin D deficiency group (less than or equal to 50 nmol/L) had a 4.4 times higher risk of dying from the disease than those in the diabetic comparator group. For people with diabetes, it is therefore particularly important that the vitamin D content in the body is well regulated and that no deficiency symptoms appear.

At the end of the study, the scientists came to a clear conclusion: a strong link can be confirmed between vitamin D deficiency (below 50 nmol/l) and increased mortality. It is therefore recommended that everyone always monitor their own level of vitamin D in the body in order to avoid deficiency symptoms and an increased risk of death.
