Diabetes

The clinical course and prognosis of COVID-19 in patients with diabetes are in line with average standards, however in some particular cases severe consequences may occur. In particular, in individuals hospitalized with diabetic ketoacidosis (DKA), the prognosis is significantly worse for those who also suffer from COVID-19, and data show that death in the hospital was six times greater among patients with DKA who also had COVID-19 than those who were not affected.

Type 2 diabetes mellitus consists of a series of dysfunctions characterized by hyperglycaemia and resulting from the combination of insulin resistance, inadequate insulin secretion and excessive or inappropriate glucagon secretion. Poorly controlled type 2 diabetes is associated with a number of microvascular complications and neuropathic symptoms.

Diabetes is a group of clinical syndromes with glucose metabolism disorder as the main manifestation caused by genetic and environmental factors. There are mainly two types of diabetes, type 1 and type 2. There are certain differences in the etiology, morbidity, symptoms, disease characteristics, management, and impact of these two types of diabetes.

A person suffering from diabetes is like entering a vicious circle of falling down: On the one hand, a low level of insulin secreted by the pancreas, the amount secreted into the blood increases as the blood glucose rises, on the other hand, high blood sugar will further damage the islet, aggravating the lack of insulin secretion. Prolonged high blood sugar can damage nerves and organs and result complications.
