Who needs blood sugar checks? What is the significance of measuring fasting blood sugar and postprandial blood sugar?
Hello everyone, we are Red Sun Health Science. Today, I will discuss with you the topic of "diabetes". The early symptoms of diabetes vary from person to person. food, weight loss, fatigue, etc.
First of all, we must know that diabetes is a metabolic disorder. According to the type, it can be divided into type 1 diabetes and type 2 diabetes. Type 1 diabetes means that the patient cannot produce insulin by himself and needs lifelong injection of foreign insulin to maintain the normal metabolism of the body. The onset of diabetes usually occurs before the age of 35 and accounts for about 10% of the diabetic population. This must monitor blood sugar.
In fact, the most common type of diabetes in our lives is 2 diabetes, which refers to the onset of patients after the age of 35. Such patients can produce insulin by themselves, but due to decreased insulin resistance, insulin sensitivity decreases, which leads to the body's utilization of blood sugar. These patients account for a higher proportion of the diabetic population. Armed with these basics, let's go back to what we just discussed.
Friends who need to go to the hospital to check blood sugar
Recently, oral symptoms such as dry mouth and thirst, or oral mucosa petechiae, ecchymosis, edema, and burning sensation in the mouth. Oral symptoms are often a precursor to diabetes. Generally, patients with impaired glucose tolerance often have dry mouth and polydipsia, a burning sensation, swollen gums, and toothache.
Those with a rapid decline in vision or a foggy feeling in the near future, and those with rapid progress of cataract.
Those with unexplained extremity ulceration and gangrene, those who are prone to purulent cysts, carbuncles, furuncles, sores, etc. on the skin, and those who are not easy to heal, those who have wound infections that cannot be cured for a long time, or those who are not easy to heal from surgical wounds.
Those who are often tired, weak, weak and dizzy. Those who have hypoglycemia reactions such as palpitation, tremors, and cold sweats may often feel fasting
Those who are over 35 years old and have a family history of diabetes.
Those who were originally fat but have recently lost weight for unknown reasons.
The skin is dry and itchy, and there is no obvious improvement with antipruritic drugs, especially those whose special parts are ineffective after anti-inflammatory and antifungal treatment.
People with abnormal skin paresthesia, limb numbness, sluggishness, feeling of ant crawling, paresthesia, burning pain, acupuncture pain, etc.
The appearance of the above symptoms may be an early manifestation of diabetes. We generally recommend that people over 35 years old go to the hospital to check blood sugar. But many friends will encounter many indicators such as fasting blood sugar and postprandial blood sugar when they go to the hospital for examination. What do they mean? Let us explain to you separately.
Fasting blood sugar: Strictly speaking, fasting blood sugar refers to the blood sugar value measured before breakfast the next day after an overnight fast (except drinking water) for 8-12 hours (note: blood sugar measured before lunch and dinner cannot be called fasting blood sugar) ), its normal value is 3.9~6.1 mmol/L. Fasting blood glucose is less disturbed by other factors and has good repeatability, and can be used as an important diagnostic indicator for diabetes.
Postprandial blood sugar: Many friends feel that the doctor asked them to measure their fasting blood sugar. Why do they need to measure postprandial blood sugar? Is it over-checking, not really. Postprandial blood sugar is strictly called "2-hour postprandial blood sugar". Blood sugar 2 hours after a meal, it refers to the time from the first bite of the meal. The normal value of blood sugar measured by blood sampling after 2 hours is 4.4~7.8 mmol/L.
"2-hour postprandial blood glucose" can reflect the patient's islet cell reserve function to a certain extent (that is, the ability of islet cells to stimulate additional insulin secretion after eating), which cannot be reflected by fasting blood glucose. Contribute to the early diagnosis of type 2 diabetes and reduce missed diagnosis. Because many friends with early diabetes, fasting blood sugar is normal, while postprandial blood sugar rises. This is because their basal insulin secretion is acceptable, but the large doses of insulin stimulated by meals are reduced. Therefore, it is necessary to monitor blood glucose 2 hours after meals.
- We will also add a "glycated hemoglobin" to everyone. This indicator is often used as the gold standard for blood sugar control. The glycated hemoglobin accurately reflects the average blood sugar level for a relatively long period of time (2-3 months). Short-term lifestyle changes, such as short-term dieting or exercise in the days or weeks before the diagnosis, can significantly affect the fasting blood glucose test, but will not affect the results of the glycated hemoglobin test, so I hope everyone knows this indicator.
Diabetes is a lifelong chronic disease, so in addition to clinical treatment, a balanced, scientific and reasonable diet should also be carried out, and the clinical cure rate of diabetes should be improved through dietary therapy.
