Several risk factors (old age, hypertension, cardiovascular disease, immunodeficiency) have been related with coronavirus disease 2019 (COVID 19). Among them, Diabetes Mellitus (DM) and obesity are recognized to increase the susceptibility and severity of the infection. A higher inflammatory response observed in these patients, the immune system dysfunction and increased expression of angiotensin converting enzyme 2 (ACE2) which is a the target for SARS-CoV-2, contribute to the worse outcome of diabetic and obese patients. Adequate blood glucose control improves the prognosis, while critically ill COVID 19 patients with high metabolic risk should be monitored for new onset DM.
