After Covid-19, it was observed that in the insulin-producing cells of the pancreas, certain cell structures responsible for the release of insulin had decreased. Some patients developed insulin resistance after the disease and had elevated blood sugar levels, even though they did not previously have diabetes. This prompted researchers to examine the data of almost nine million patients from 1,171 medical practices across Germany. It was found that among 35,865 people who had Covid-19, type 2 diabetes was diagnosed more frequently than among people with other respiratory diseases. Of those with coronavirus infection, 15.8 per 1,000 people developed type 2 diabetes, compared to only 12.3 per 1,000 people with other respiratory diseases.
Infection with SARS-CoV-2 can lead to a strong release of pro-inflammatory messenger substances (cytokines). Activation of the immune system can continue for months after infection and impair insulin action. Although type 2 diabetes is unlikely to be a problem for most people with mild Covid-19 disease, the authors recommend that anyone who has recovered from Covid-19 be screened for diabetes warning signs, such as fatigue, frequent urination and weight gain Durst respects and advise to consult a doctor’s office in case of doubt.
