Final answer:
Type 2 diabetes is the most common form of diabetes, characterized by insulin resistance, often linked to obesity. Prevention and treatment involve lifestyle changes and medications/insulin injections.
Step-by-step explanation:
Type 2 diabetes is the most common form of diabetes, accounting for 90% of cases. It is characterized by insulin resistance, which means the body's cells become unresponsive to insulin. This condition is often linked to obesity and can lead to serious health problems if poorly controlled. Prevention and treatment of type 2 diabetes involve making lifestyle changes such as following a healthy diet, engaging in regular physical activity, and maintaining a normal body weight. Medications and insulin injections may also be used as part of the treatment.
