Final answer:
Type 2 diabetes accounts for 90-95% of all diabetes cases and is characterized by insulin resistance and lifestyle-related risk factors. It differs from the autoimmune type 1 diabetes and can often be managed with lifestyle changes.
Step-by-step explanation:
The type of diabetes that accounts for 90-95% of all cases is type 2 diabetes. This form of diabetes is associated with insulin resistance, where the body's cells become less responsive to insulin, which is crucial for regulating blood sugar levels. Over time, this insulin resistance can be coupled with a decrease in insulin production from the pancreas. Contributing factors to the development of type 2 diabetes include genetics and lifestyle choices, such as poor diet and lack of physical activity, leading to obesity. Unlike type 1 diabetes, which is an autoimmune condition where the immune system attacks pancreatic beta cells, thus eliminating insulin production, type 2 diabetes can often be managed or even reversed with lifestyle modifications such as weight loss, increased physical activity, and a healthy diet.
