Nowadays, the diabetic population is on the rise. Many people find that their blood sugar levels are too high during the physical examination. At this time, they are very panicked and mistakenly think that they have diabetes.

In fact, diabetes is a chronic systemic metabolic disease caused by the long-term interaction of environmental factors and genetic factors.

Most diseases are eaten by people, especially high blood sugar, which is known as one of the three highs. Often eating spicy, high-salt, high-oil, and high-sugar foods will cause such diseases to occur.

To accurately measure the fasting blood glucose concentration, you need to pay attention to the following 3 things to ensure accurate blood glucose measurement:

One: Fasting for at least eight hours

Eight hours before blood draw in the morning, you can't eat calorie food, try not to drink water.

Second: Precautions in the measurement process

After disinfecting the fingertips and quickly puncturing the skin with a needle, the first drop of blood should be wiped off with a cotton swab, and the second drop of blood should be collected for measurement to avoid mixing alcohol in the blood to affect the measurement results.

Third: Make sure to get enough sleep before measuring fasting blood sugar

Avoid emotional agitation, excessively strenuous activity, etc., which can lead to elevated blood sugar.

●Learn about diabetes

Diabetes is a metabolic disease characterized by hyperglycemia. Hyperglycemia is caused by impaired biological activity or defective insulin secretion, or both. Long-term hyperglycemia in diabetes causes various tissues, especially blood vessels, heart , chronic damage to liver, kidney and nerve, dysfunction.

In severe or emergency situations, acute and severe metabolic disorders, diabetic ketoacidosis, hyperglycemia and hyperosmolarity can occur. The etiology of diabetes may be related to obesity and genetic factors.

Current lifestyle, age over 45 years old, history of macrosomia, viral infection, autoimmune system deficiency, mental factors and genetic factors are related.

Types of diabetes:

Type 1 diabetes: Type 1 diabetes is the destruction of pancreatic beta cells due to immune-mediated or idiopathic factors, usually resulting in absolute insulin deficiency.

Type 2 diabetes: Insulin resistance and defective islet B cell function, leading to diabetes caused by relative insulin deficiency. It is the most common type of diabetes in Chinese patients.

Is fasting blood sugar 8.5 serious?

The normal range of fasting blood sugar in normal people is 3.9-6.1mmol/L, the normal value of blood sugar 2 hours after meals is <7.8mmol/L, if fasting blood sugar ≥ 7.0mmol/L or blood sugar 2 hours after meals ≥ 11.1mmol/L , and the retest on another day is still greater than the normal value, which can diagnose diabetes.

There are three diagnostic criteria for diabetes: one is fasting blood glucose ≥ 7.0 mmol/L.

Blood sugar refers to venous plasma glucose, not fingertip blood sugar. Because fingertip blood sugar has errors, it is only used to monitor blood sugar, so blood tests must be drawn for the diagnosis of diabetes.

The doctor said frankly: these 3 situations, don't worry too much

• elderly

After a certain age, various functions of the body will decline. For the elderly, because the body has metabolic disorders, the standard of fasting blood sugar is higher than that of young people.

For the elderly over 60 years old, the requirements for fasting blood sugar are not so strict, as long as it is controlled at 8.0mmol/L.

If you have high blood pressure, then the fasting blood sugar is 8.5mmol/L, so there is no need to worry too much.

• pregnant woman

During pregnancy, the overall state of a woman’s body will change, and the original functional state cannot be used as the standard. For example, the pregnant human body is affected by progesterone, resulting in a significantly lower endocrine level of hormones than before, which will reduce the metabolic function of hormones. .

If you are in a state of high blood sugar for a long time during pregnancy, it is very unfavorable for the fetus in the abdomen, and it is easy to cause hypoglycemia in the fetus after birth. Therefore, blood sugar must be strictly controlled during pregnancy. Through data research, it is found that pregnant women are fasting in their daily life. Blood glucose data should remain stable within the range of 5.1mmol/L.

When there is a significant difference between the blood sugar control value and the clinical standard, and the blood sugar value is much higher than the expected blood sugar value, it is the performance of "gestational diabetes mellitus".

• emotional tension

30 minutes before measuring the blood sugar value, do not engage in heavy physical activities, it is best not to exercise vigorously, do not be overly anxious, relax your body, and maintain a calm mind.

For some people who are emotionally stressed, in this case, the normal test results will be affected. In this case, if the measured blood sugar level is higher than 8.5, there is no need to worry too much. You can relax your emotions and come again. Measure it.
