The normal blood glucose level in the fasting state is between 3.5 and 5.5 mmol/1 blood; four or five times that amount is found in diabetics, owing to insufficient insulin in the blood, possibly accompanied by an excessive carbohydrate intake. Untreated, it may lead to diabetic coma.
Hyperglycemia refers to an abnormally elevated level of glucose in the blood, commonly observed in individuals with untreated or poorly managed diabetes mellitus. Moreover, people with diabetes may experience hyperglycemia due to factors such as infections, stress, or surgical procedures.
