I measured my fingertip blood sugar 13 with a blood glucose meter on an empty stomach, and my friend

Fasting blood glucose refers to the blood sugar measured after fasting for 8 to 10 hours.

I can tell you that the diagnostic criteria for diabetes are: two fasting blood glucose levels above millimole liters; Blood glucose greater than or equal to millimoles after more than two meal measurements; If fasting and postprandial blood glucose do not meet the above standards, and the fasting blood glucose is between millimole liters, the blood glucose should be measured two hours after taking 75 grams of glucose water on an empty stomach so that it is greater than or equal to millimol liters. If you meet any of the above 3 criteria, you can be diagnosed with diabetes.

In terms of diabetes diagnosis, if there are typical symptoms (three more and one less: polydipsia, polyphagia, polyuria, weight loss) and blood sugar exceeding any time is diabetes, it can be diagnosed at one time. If there are no typical symptoms, fasting is more than 2 hours after a meal, and it needs to be repeated at least once at different times to confirm the diagnosis.

It is recommended to test it again, and fasting is only available in the morning, fasting refers to things that have not eaten calories for more than 8 hours, and other time periods are not counted. In addition, if there is a deviation in the blood glucose meter before, choose a blood glucose meter with a good reputation to test it, and the fasting should not exceed 6 hours after meals and not more than 8 after 2 hours.

Please pay attention to a light diet, regular work and rest, and then go to the hospital to measure blood sugar from a biochemical instrument after a few days, the standard of diabetes is no diabetes symptoms, if the fasting blood sugar is greater than 7mmol L more than twice, or there is an oral 75g anhydrous glucose measured 2 hours after the blood sugar is measured more than fasting refers to eight hours of no energy intake).Look at your blood sugar measurements to judge.

The following are the diagnostic criteria for diabetes, which is how it is diagnosed in the hospital.

1) Fasting plasma glucose (FPG): FPG (normal, <126mg DL) is impaired fasting blood glucose (IFG), diabetes mellitus, and needs to be reconfirmed on another day. Let's use pre-breakfast blood sugar to represent fasting blood sugar.

2) 2-hour plasma glucose (2HPG): 2HPG (normal, <200mg DL) in OGTT is IGT (decreased glucose tolerance), which is diabetes mellitus and needs to be reconfirmed on another day. This test is done in a hospital.

3) Diagnostic criteria for diabetes: diabetes symptoms + random blood glucose, or FPG, or 2HPG in 0gtt. If the symptoms are atypical, it needs to be reconfirmed on another day, and a third OGTT is not recommended

You may have diabetes, think about whether there are symptoms of polyphagia, polydipsia, polyuria, weight loss, and go to the hospital tomorrow The doctor may ask you to check your fasting blood sugar + glycosylated hemoglobin, and it will be really clear.

It is recommended that you go to the hospital in the morning for an examination on an empty stomach, sometimes a large amount of high sugar content may also cause a temporary increase in blood sugar.

1. It depends on how high your blood sugar is, if it is confirmed that diabetes must be regular**, if it is prediabetes (blood sugar is high to normal but below the diagnostic standard of diabetes), you can rely on diet and exercise to adjust. If your blood sugar is high, you can consider eating bitter gourd, celery, fungus, seaweed, onion, shiitake mushroom, grapefruit, pumpkin and whole grains to lower blood sugar, which is the most ideal food for diabetics.

2. High blood sugar, you must pay attention to diet! Don't eat foods high in sugar! It is recommended to use glucagin capsules to quench thirst, nourish the stomach, and astringent and solidify yin.

It is used for polydipsia, polyuria, polyphagia, weight loss, fatigue and weakness, increased urine glucose and blood sugar; Mild and moderate adult-onset diabetes.
