Abstract:
The prevalence of chronic metabolic diseases in Mexico is high, being type 2 Diabetes mellitus (T2DM) as the most common disease. Several studies have shown that, compared with healthy individuals, patients with T2DM suffer a higher severity and mortality of Coronavirus disease 2019 (COVID-19). Therefore, it is important to the knowledge of the bidirectional relationship between these diseases. T2DM can increase SARS-CoV-2 virus pathogenicity in part due to metabolic disturbance. As a result, COVID-19 susceptibility and severity rise in diabetic individuals, which makes them a high-risk population. On the other hand, the infection caused by SARS-CoV-2 can lead individuals to hyperglycemia or new-onset diabetes. In order to understand the relationship between COVID-19 and T2DM, this review aims to emphasize the tropism of the SARS-CoV-2 virus to pancreatic beta-cells, as well as the physiologic effects of these.

Carbohydrate Metabolism
Starch accounts for approximately 60% of the carbohydrates consumed by humans. Since amylase enzymes cannot function in the stomach's acidic environment, starch can only be digested in the mouth and small intestine. Simple sugars are found naturally in milk and fruits in...

Type 1 diabetes is an autoimmune disease in which the immune system mistakenly attacks and destroys the insulin-producing beta cells in the pancreas. As a result, the body is unable to produce sufficient insulin, and individuals with...
Pathophysiology of Diabetes
Type 1 diabetes is characterized by autoimmune-mediated destruction of pancreatic β cells, with environmental factors potentially triggering this process in genetically susceptible individuals. Despite many not having a family history, certain genes increase susceptibility,...
