How does diabetes affect the risk of stroke?

If people in middle age have diabetes, this increases their chances of having a stroke later in life by almost a third.

A recent study by the Karolinska Institute in Stockholm found that middle-aged diabetes affects the risk of developing a stroke. The results of the study were published in the English-language journal "Diabetologia", the journal of the European Association for the Study of Diabetes.

Why does diabetes increase the risk of stroke?

The Swedish study found that people who have type 2 diabetes related to obesity at 40 or 50 years of age have a higher risk of stroke after reaching the age of 60. This is because diabetes triggers an accumulation of sugar and fat particles in blood vessels, which causes the arteries that supply the brain with blood to narrow. The investigation has raised concerns that the obesity epidemic, which has led to an explosive increase in cases of type 2 diabetes, could lead to an increase in strokes in the further course. Middle-aged diabetics have a stroke almost a third more often later than people without diabetes, the researchers report.

Data from 33,000 twins were evaluated for the study

For the study, the patient files of 33,000 twins born in the 1960s were analyzed. The researchers wanted to find out whether there is a connection between diabetes and strokes. It turned out that patients who had type 2 diabetes between the ages of 40 and 59 had a 30 percent higher risk of developing a stroke later in life after the age of 60. In addition, they were twice as likely to suffer from narrowing of the arteries in their brains, one of the main causes of strokes. The data from twins were evaluated in order to exclude genetic factors that increase the likelihood of a stroke. The results found underline the need to control type 2 diabetes, especially in middle age, in order to reduce the frequency of strokes caused by damage to the arteries.

How many people in Germany suffer from diabetes?

Diabetes leads to high costs for the health system, the disease has already been described as the greatest health crisis of our time. Many people suffer from type 2 diabetes related to obesity. And millions of people around the world have the disease without even knowing about it, the researchers explain. In 2012, the German health survey found that 7.2 percent of the population in Germany had diagnosed diabetes, and another 2.1 percent had diabetes that had not yet been diagnosed. The data are based on a representative national population sample of people aged 18 to 79. In the group of people over the age of 65, between 16 and 23 percent are affected by diabetes in Germany.
