“…Diabetes mellitus (DM), including type 1 DM (T1DM) and type 2 DM (T2DM), is a common but complex disease, associated with lots of comorbidities and a leading cause of mortality. 1–8 Risk factors associated with developing DM, especially T2DM accounting for >90% of all cases of DM worldwide, include elderly population, 9–11 family history (multiple genes), 11–18 overweight, 3,4,17–21 obesity, 3,4,17–21 pregnancy, such as the development of gestational DM, 21–24 dietary (calories intake, fibers, essential micronutrition, and mineral elements), 25–29 lifestyle factors (exercise, rest, and others), 3,4,30–32 environmental factors, interactions with other microorganisms (microbiotas), and many others. 33–35 The key pathophysiologic mechanism of DM is based on the inability of faulty pancreatic β-cells to secret a normal amount of insulin to maintain normal body consumption, and/or peripheral tissue has a decreased susceptibility to insulin, resulting in hyperglycemia and insulin resistance.…”
