15 Complications Linked To Prediabetes

5. High Cholesterol

High cholesterol is often associated with prediabetes, and these conditions can occur at the same time. Generally, patients with prediabetes and diabetes will have reduced levels of high-density lipoprotein cholesterol (the 'good' kind) and increased levels of both triglycerides and low-density lipoprotein cholesterol (the 'bad' kind). These symptoms are indicative of a condition known as diabetic dyslipidemia, and they are linked to the increased insulin resistance that often begins in prediabetic patients. Cholesterol is usually measured through a fasting blood test. For mild cases of high cholesterol, dietary modifications may bring cholesterol readings back to within the normal range. Many patients will be prescribed statins and other medications to successfully reduce their cholesterol.

6. Nerve Damage (Peripheral Neuropathy)

One of the earliest complications of elevated blood sugar—even in the prediabetic range—is nerve damage, also known as peripheral neuropathy. This condition typically affects the feet and legs first, causing tingling, numbness, burning, or sharp pain. In some cases, individuals may lose sensation altogether, which increases the risk of unnoticed injuries. Although more common in diabetes, research shows that even prediabetic glucose levels can impair nerve function over time. Regular foot exams, improved blood sugar control, and physical activity can all help slow or prevent the onset of neuropathy in prediabetic individuals.
