Do you have friends who eat and drink too much, run to the toilet all the time and lose a lap suddenly? When "more than three and less" occurs, diabetes has been coming to our door for a period of time. At this time, blood sugar has been soaring, and the risk of complications increases. In fact, the prevention of diabetes is easier than you think. Through regular examination, early detection and treatment, and improvement of living and eating habits, you can stay away from annoying diabetes! How to diagnose diabetes? Next, I'd like to share my views with you.

How to diagnose diabetes?

Blood glucose is the only standard for the diagnosis of diabetes. Patients with obvious "three more and less" symptoms can be diagnosed as long as abnormal blood glucose value is once. Asymptomatic patients need two abnormal blood glucose levels to diagnose diabetes. 75 g glucose tolerance test should be done for suspicious patients.

Urine sugar is often positive. When the blood glucose concentration exceeds the renal glucose threshold (160-180 mg / dl), the urine glucose is positive. When the renal glucose threshold is increased, even if the blood glucose reaches the level of diabetes, the diagnosis can be negative. Therefore, urine glucose determination is not a diagnostic standard.

Glycosylated hemoglobin (HbA1c) is the product of non enzymatic reaction between glucose and hemoglobin. The reaction is irreversible and the level of HbA1c is stable. It can reflect the average blood glucose level in two months before blood collection. It is the most valuable index to judge the state of blood glucose control.

matters needing attention

Don't drink. Because the alcohol contained in the wine does not contain other nutrients, it can only provide heat, and each gram of alcohol produces about 7 kcal (294 coke). Long term drinking is not good for the liver, and it is easy to cause the increase of serum triglyceride. A small number of patients taking sulfonylurea hypoglycemic drugs are prone to panic, shortness of breath, cheek redness and other reactions after drinking. Fasting drinking is easy to cause hypoglycemia in patients with insulin, so it is better not to drink for the safety of patients.
