What complication is a patient with diabetes at risk for if their blood glucose levels are poorly controlled?

A patient with diabetes who has poorly controlled blood glucose levels is at increased risk for a variety of complications, and one of the most significant is the development of cardiovascular diseases and neuropathy.

Chronic hyperglycemia, or sustained high blood sugar levels, can lead to damage in blood vessels and nerves over time. This can result in conditions such as atherosclerosis, where arteries become hardened and narrowed, leading to an increased risk of heart attack and stroke. Additionally, poorly controlled diabetes can also cause neuropathy, which is nerve damage that often presents with pain, tingling, or loss of feeling, particularly in the extremities.

These complications stem from the underlying pathophysiology of diabetes, where elevated glucose levels can lead to increased oxidative stress and inflammation, further contributing to vascular and nerve injury. Managing blood glucose levels effectively is crucial to reducing the risk of these serious health outcomes. In contrast, improved insulin sensitivity and enhanced vision clarity would not arise from poor blood glucose control; rather, they are associated with effective diabetes management and lifestyle modifications. Similarly, while skin infections may be a concern due to the impact of diabetes on immune function, they do not reflect the comprehensive risks posed by cardiovascular diseases and peripheral neuropathy, which are more directly
