The severity of a blood glucose level of 13 mmol/L should depend on the condition, and if it is a fasting blood glucose of 13 mmol/L, then it is very serious and should be treated promptly with glucose-lowering therapy, commonly with oral medications and subcutaneous insulin injections.
In contrast, if the postprandial blood glucose is 13 mmol/L, especially two hours after the meal, it is less severe, but should be taken seriously.
This range of blood glucose, whether fasting or postprandial, is diagnostic of elevated blood glucose, and the specific cause should be promptly identified. The causes of elevated blood glucose include both physiological and pathological factors. Most of the physiological factors are caused by the stress reaction, and have a great relationship with the living condition, diet and sleep quality, etc. Generally, the blood sugar can be restored after the body function is restored to normal. While pathological factors consider diabetes, trauma, gastrointestinal reaction, hyperthyroidism, hyperthermia and many other factors, in principle, it is recommended to actively treat the primary disease. During treatment, blood glucose should be closely monitored, the type of medication as well as the dosage should be adjusted according to the blood glucose level, and the diabetic diet and exercise should be paid attention to.
