Even mild COVID-19 infection raises blood sugar and risk of incident diabetes
The human pancreas is a target of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Following SARS-CoV-2 infections, reduced numbers of insulin secretory granules in beta cells and impaired glucose-stimulated insulin secretion have been observed.
To add further value, a recent study suggests that individuals with COVID 19 had increased type 2 diabetes incidence than patients with acute upper respiratory tract infections (AURI). The study findings were published in the journal Diabetologia on March 16, 2022.
New-onset hyperglycaemia or high blood sugar and insulin resistance have been reported in patients with coronavirus disease-2019 (Covid-19) without a history of diabetes. However, it is unclear whether such metabolic alterations are transient or whether individuals with Covid-19 have an increased future risk of persisting diabetes. Therefore, Dr Wolfgang Rathmann and his team conducted a study to investigate diabetes incidence after infection with Covid-19. Individuals with AURI, which are frequently caused by viruses, were selected as a non-exposed control group.
