What are the causes of type 2 diabetes?

Type 2 Diabetes: Insulin Resistance
In type 2 diabetes, the body's cells cannot take up glucose properly, leading to high levels of glucose in the blood.

Diabetes is a chronic disease characterized by increased blood sugar (glucose) level.  Diabetes is caused by either insufficient insulin secretion or resistance to that hormone’s action. 

Insulin is produced by the pancreas and helps process the glucose in the blood. Thus, with inadequate insulin, the bodies can’t burn all the blood sugar for energy in an efficient way. This means the glucose level in the blood rises, causing a variety of symptoms and when severe may even lead to death

An estimated 9.4% of the population in the United States (30.3 million) were affected by diabetes in 2017, according to the report by the U.S. Centers for Disease Control and Prevention (CDC).
