A. Diabetes, a pro-inflammatory condition by itself, reacts with Covid-19 and increases the likelihood of an inflammatory reaction and worsening blood sugar levels. For those with known diabetes, Covid-19 causes abnormal blood glucose levels to exceed (above the normal range). Using steroids for Covid-19 made the patients' glucose levels even worse. Diabetes-related high blood sugar left untreated can have significant health effects and harm kidneys, nerves, and eyes. Patients recuperating from Covid-19 are encouraged to monitor their blood sugar levels regularly for a more accurate diagnosis.
