What condition can be exacerbated by excessive insulin in the blood?

Excessive insulin in the blood is closely linked to conditions like insulin resistance and contributes to the progression of diabetes, particularly Type 2 diabetes. When high levels of insulin persist over time, the body's cells become less responsive to the hormone, leading to a cycle of elevated blood sugar levels and even more insulin production. This condition not only complicates the management of diabetes but can also increase the risk of severe complications associated with the disease, including cardiovascular issues and nerve damage. Therefore, recognizing the impact of excessive insulin is crucial for understanding how it can worsen diabetes and, consequently, why this is the correct answer.

In contrast, heart disease, hypertension, and obesity are related conditions that can also be influenced by insulin levels, but excessive insulin is not directly recognized as a primary exacerbating factor for these conditions in the same manner as it is for diabetes.
