Many people with high blood sugar levels are told by their doctors that they don’t have diabetes because their fasting blood sugar levels are normal. Normal is below 100 milligrams per decilitre (mg/dl).
But here is the problem: Early in the disease, diabetics often have a “normal” fasting blood sugar, yet one hour after they eat, their blood sugar levels rise above 140. This signals that they are at increased risk for heart attacks, strokes, cancers, nerve damage and premature death.
