Glycemia Journals The goal of diabetes treatment is the maintenance of an adequate metabolic control to prevent or delay the development of complications. However, therapeutic efforts to keep the values of glycated hemoglobin within the recommended target in many cases lead to an increased risk of hypoglycemia. High-glycemic foods can cause a rise in blood glucose, which can last for a longer time in the blood. Low-glycemic foods can cause a small blood sugar increase that usually does not last as long. This is essential for life but the amounts must remain within strict limits. Hypoglycemia, also known as low blood sugar, is a fall in blood sugar to levels below normal. This may result in a variety of symptoms including clumsiness, trouble talking, confusion, loss of consciousness, seizures or death.
