1. Higher than normal blood glucose levels
Prediabetes is characterized by higher than normal blood glucose levels, often in the range of 100 to 125 milligrams per deciliter for fasting glucose and between 5.7 and 6.4 percent for hemoglobin A1C. This condition is also known as impaired glucose tolerance (IGT) or impaired fasting blood glucose (IFG).
2. Unexplained fatigue
People with prediabetes often have insulin resistance, meaning their bodies cannot efficiently convert blood glucose into energy, leading to unexplained fatigue. This fatigue can occur even without physical exertion.
3. Slow wound healing
People with prediabetes may experience slow wound healing. Over time, high blood sugar can damage the walls of small blood vessels, reducing blood flow and, consequently, slowing healing.
4. Unexplained mood swings
