Is it serious if the blood sugar is over 13? What is the normal range of blood sugar?

People with high blood sugar need to strictly control their blood sugar. In order not to develop diabetes, they need to test their blood sugar level 24 hours a day. If the blood sugar level becomes higher, intervention is needed as soon as possible. So is a blood sugar test result of more than 13 points serious?

Is blood sugar level above 13 serious?

Blood sugar of 13 points is relatively high, whether it is fasting blood sugar or postprandial blood sugar, it is over the standard. If the fasting blood sugar value reaches 13, it proves that the current condition is very bad and the patient is at high risk of acute complications. Intervention measures need to be taken in time and cannot be left unchecked.

The erosion of high blood sugar on the human body is chronic, and it is impossible to cause obvious discomfort in a short period of time. Only after a long period of development will pathological changes occur in various organs of the body. At this time, many people regret it.

What is the normal range for blood sugar?

Because the human body's blood sugar level will change before and after meals, it is generally tested in three stages: fasting, 2 hours after meals, and during meals.

Fasting blood sugar refers to the blood sugar measured 8 to 12 hours after a meal. During this period, no food should be consumed except a small amount of drinking water. Standard value: 3.9-6.1mmol/L

Blood sugar level is measured 2 hours after a meal, starting from the first bite of food. Test the blood sugar level 2 hours after a meal. Standard value: 4.4-7.8mmol/L

Blood sugar during a meal refers to the blood sugar measured at any time within 2 hours after a meal. Maximum value: 9.4mmol/L

Note: These three blood sugar value indicators must meet the standards at the same time to be considered normal blood sugar.

Normal blood sugar level reference

Normal people's fasting blood sugar is less than 6.1, and 2 hours after a meal is less than 7.8. If strictly controlled, it can be controlled according to the normal standard. The general requirement for diabetic patients' blood sugar is fasting <7.0, and two hours after a meal <10.0.

If the disease has lasted for a long time and the patient is older, the control range can be relaxed to fasting <9.0 and meal two <11.1.

If the patient has a tendency to hypoglycemia, has severe cardiovascular disease, tumors, or a short life expectancy, the requirements can be relaxed a little bit, with the fasting blood sugar level controlled within 10.0 and the post-meal blood sugar level controlled within 13.0.

In short, different people have different blood sugar control standards, so you should consult a doctor for detailed standards.
