Type 2 diabetes is most commonly caused by which of the following?

• A. A Deficiency Of Insulin Production Alone
• B. A Combination Of Lifestyle And Genetics
• C. A Bacterial Infection
• D. Exclusively Genetic Factors

Answer: (B)

Type 2 diabetes arises from multiple interacting factors, with insulin resistance tied to lifestyle and a person’s genetic makeup. When cells don’t respond well to insulin, the body tries to compensate by producing more insulin, but over time the pancreas can’t keep up, and blood glucose rises. Obesity, physical inactivity, and unhealthy eating patterns increase insulin resistance, while genetics can set a higher baseline risk. Because both environment and genetics contribute, it’s not just a deficiency of insulin production, nor caused by an infection, nor determined exclusively by genes. The combination of lifestyle factors and genetics best explains why Type 2 diabetes develops in most people.
