Recent research found that people who have had a COVID-19 infection are 40 percent more likely to be diagnosed with diabetes in the following year, and how severe the case was doesn’t seem to play a major factor. The risk of diabetes was higher for individuals who experienced more severe forms of COVID-19, but the increased risk was also found in patients with milder cases. Most patients in the study developed Type 2 diabetes—symptoms can include frequent urination, increased thirst, fatigue, blurred vision, extreme hunger, wounds that are slow to heal, and numbness or tingling in the hands or feet.
