refers to blood glucose measurement

diagnosis of diabetes

More than half of the world’s blind people, more than half of the amputees, near Half of the patients with cardiovascular and cerebrovascular diseases are caused by diabetes. What a shocking number this is! It is imperative to pay attention to diabetes as a lifelong disease. Diagnosing diabetes using blood glucose levels has a uniform standard worldwide. That is, normal people’s blood sugar should be less than 6.1 millimoles per liter of fasting blood glucose, and blood glucose should be less than 7.8 millimoles per liter two hours after a meal. If one of these two items exceeds this normal value, it means that the blood sugar is abnormal. If the fasting blood sugar is greater than or equal to 7.0 mmol/L, or the blood glucose is greater than or equal to 11.1 mmol/L after 2 hours, you can diagnose Already suffering from diabetes.

Self-monitoring of blood glucose

The prevalence of fasting blood glucose in diabetic patients and the tendency to ignore postprandial blood glucose are important.

1. Fasting blood glucose monitoring:

(1) Normal value: 3.9-6.1 mmol/L.

(2) Sumuji phenomenon: too much medication in the evening, plus no meals before going to bed, causing hypoglycemia in the patient’s night (especially in the early morning), which in turn leads to the subsequent rebound of fasting blood glucose. The phenomenon is the Su Muji phenomenon. For this reason, fasting blood glucose rise, patients should reduce the dose of oral hypoglycemic drugs or insulin before dinner or appropriate meals before going to bed; can also be used together.

(3) Dawn phenomenon: After midnight, the body’s growth hormone, glucocorticoids and other blood glucose levels increase, and its secretion peak generally occurs between the early morning and the morning, resulting in a fasting blood glucose rise. High, for the dawn phenomenon. For this reason, elevated blood sugar can be resolved by taking oral hypoglycemic agents after dinner and/or long-acting insulin in a subcutaneous injection before going to bed.

(4) Identification of Sumuji phenomenon and dawn phenomenon: patients should measure fasting blood glucose at 3 am and morning, respectively. If blood sugar is not low at 3 am, and fasting blood sugar rises in the morning, it is dawn phenomenon; On the other hand, if the blood sugar is lower than normal at 3 am and the blood sugar rises in the morning, it is a Su Muji phenomenon.

2. 2 hours postprandial blood glucose monitoring:

(1) Normal value: 4.4-7.8 mmol/L.

(2) Clinical significance: 2 hours postprandial blood glucose reflects the reserve function of insulin β cells in patients to some extent. After eating, food stimulates the ability of insulin beta cells to secrete extracellular insulin, which helps early diagnosis of type 2 diabetes and reduces missed diagnosis. Because many early diabetic patients have fasting blood glucose and postprandial blood glucose. This is due to the fact that the patient’s basal insulin secretion is still acceptable, and the insulin stimulated by the meal cannot be caused by a large amount of secretion. Postprandial hyperglycemia is also an independent risk factor for diabetic complications. Its predictive value for the risk of death in diabetic patients is superior to fasting blood glucose and glycated hemoglobin.

Standards for blood glucose monitoring compliance

The standard for achieving this is this, and it is best to reach normal standards. If the diabetic patient does not meet the normal standard, as long as the fasting blood glucose is less than 7.0 mmol/L, and the blood glucose is less than 10 mmol/L 2 hours after the meal, it is a clinically acceptable standard. Of course, it is better if a diabetic patient, especially a younger diabetic, has a fasting blood glucose of 6.1 mmol/L and a 2-hour postprandial blood glucose of 7.8 mmol/L.
