Prediabetes is a condition in which blood glucose levels are higher than normal but not high enough for a diagnosis of diabetes.
It may progress to type-2 diabetes unless you take steps to prevent it. Losing weight, appropriate diet and regular physical activity can help.
It is a common misunderstanding that prediabetes is not a health risk until it turns into type-2 diabetes. But in reality, the difference between the two is merely on a reference scale. Any amount of increased blood sugar levels is harmful for the body, putting prediabetics at an increased risk for heart attack, stroke, kidney disorders, diseases of the eye and other health issues.
