Final answer:
Type 2 diabetes is the most common form of diabetes, accounting for about 90% of all cases. It is mainly managed with lifestyle changes, but can also require medication or insulin.
Step-by-step explanation:
The most common form of diabetes is (C) Type 2 diabetes. Type 2 diabetes accounts for about 90% of all diabetes cases and is characterized by insulin resistance and impaired insulin secretion. Both genetic and environmental factors, including obesity and a sedentary lifestyle, contribute to the development of type 2 diabetes. This form of diabetes is often managed with dietary changes, physical activity, medications, and sometimes insulin injections.
While type 1 diabetes affects about 5-10% of all diabetes cases in the United States and is an autoimmune disease that requires insulin administration, type 2 can be managed and sometimes reversed with lifestyle changes. However, if not properly managed, it can lead to serious health issues such as heart attacks and kidney failure.
