Mucormycosis and Covid 19. ... continues from last post. Approx 7.7 crore people have Diabetes Approx 47 percent are unaware of diabetic status and only 25 per cent have good sugar control. Corona itself is a hyperglycemic state. I have seen sky high levels of blood sugars in COVID patients with known diabetes. Hyperglycemia leads to polymorph( fighting white blood cells) dysfunction, impaired their moving ability towards site of infection, and their killing ability. Lesson we all must learn is STRICT SUGAR CONTROL DURING AND AFTER RECOVERY FROM COVID IS CRUCIAL TO AVOID DEADLY COMPLICATION OF MUCORMYCOSIS. I have operated several cases of Mucormycosis both in covid and non covid. Diabetes control is even crucial for better surgical outcome.
