In healthy persons, blood glucose concentration normally climbs up right after meals but it drops back to normal levels of 3.5 - 5.5 mmol/L in a couple of hours. When healthy people do not eat, blood glucose concentration is normally within this range [129]. Hyperglycaemia is the term used for an elevated glucose concentration in the blood. Diabetic patients have impaired regulatory responses. Therefore, blood glucose remains high after the meals and even when the patients do not eat. Also, otherwise healthy people under surgical stress may show diabetic responses because of elevated levels of catecholamine, a hormone which has the opposite effect of insulin. This is the main reason why surgical operations on diabetic patients are riskier.
