Evidence about the impact of COVID-19 in people with diabetes is limited, but it continues to develop. We know that people with diabetes are at higher risk of severe COVID-19 infection and complications from COVID-19. Furthermore, higher HbA1c and being overweight are linked to worse outcomes from a COVID-19 infection. COVID-19 can also contribute to worse diabetes outcomes due to factors related to the pandemic, including increased stress, changes to routine care, diet, and exercise. Also, there is a big potential for COVID-19 to worsen the inequalities in health that already exist. Researchers are now learning from previous major natural disasters to see how to reduce the impact from COVID-19 going forward.
