Hyperglycemia is a diabetic condition occurring as a result of increased blood sugar level. Healthy diabetic diet with proper medication helps in keeping blood glucose under control. High blood sugar level or hyperglycemia can be mainly divided into after meal hyperglycemia and fasting hyperglycemia depending on the time of occurrence. As the name suggests, after meal hyperglycemia or postprandial hyperglycemia normally occurs after taking meals and fasting hyperglycemia occurs after prolonged fasting. When we monitor blood glucose level, the value of sugar intensity level reaches above 180 mg/dl in the case of postprandial hyperglycemia and it reaches above 130 mg/dl in case of fasting hyperglycemic condition.
