““According to a large study from Kaiser Permanente, for every 0.05 increase above 4.72, patients had an additional 6 percent increased risk of developing diabetes in the next ten years (4.82 = 12 percent increased risk, etc.) Above 5 indicates that vascular damage has already occurred and a patient is at risk for having damage to the kidneys and eyes. Why is high fasting blood sugar a problem? High blood sugar causes vascular problems throughout your whole body, including your brain. Over time, it causes blood vessels to become brittle and vulnerable to breakage. It leads not only to diabetes but also to heart disease, strokes, visual impairment, impaired wound healing, wrinkled skin, and cognitive problems. Diabetes doubles the risk for Alzheimer’s disease.””
