The blood sugar levels fluctuate in the Covid patients. If the patient also has diabetes, then the chances are that their sugar levels shoot up. This is also happening in non-diabetic or pre-diabetic patients. Diabetes lowers the body’s immune defences.
At the same time, to help fight Covid-19, patients are prescribed steroids which act like fuel to the fire. The use of steroids reduces immunity and push up blood sugar levels in both diabetics and non-diabetic Covid-19 patients. This drop in immunity could be the reason behind rising cases of mucormycosis.
