How long does high blood sugar turn into diabetes?

High blood glucose includes impaired fasting glucose and diabetes. If it is fasting blood glucose, how long it will turn into diabetes needs to be judged according to the situation. If it is already diabetes, it does not take long to turn into diabetes.

Impaired fasting blood glucose refers to fasting blood glucose higher than normal, but it has not yet reached the diagnostic criteria for diabetes. It belongs to prediabetes. Impaired fasting blood glucose does not necessarily turn into diabetes. If the patient pays attention to diet, exercise, and monitoring blood glucose, medication can be given when necessary. It may not progress to diabetes for a long time or lifetime. If patients do not receive appropriate intervention or treatment, they may progress to diabetes, which may take six months to a year, or several years.
