Can you measure blood sugar?

Measuring blood sugar is not only expensive, but also painful. Why do people with diabetes need to monitor blood sugar?

 

  Because monitoring blood sugar is an effective way to measure whether the treatment plan is reasonable, avoid severe hypoglycemia events, and prevent diabetes complications.

 

  There is a lot of knowledge involved in measuring blood sugar. Today we will talk about the significance and control standards of blood sugar monitoring at different time points.

 

Fasting blood sugar: reflects basal blood sugar levels

  Fasting blood glucose reflects the secretion of basal insulin in the absence of sugar load stimulation, and whether the effect of medication taken at night can last until the next morning.

 

  You must also have a sense of time when measuring fasting blood sugar. The blood sugar measured between 6:00 and 8:00 in the morning when you have not eaten is called fasting blood sugar.

 

  Fasting blood glucose control standard: 4.4-7.0mmol/L.

 

Pre-meal and bedtime blood sugar: measure the action time of anti-diabetic drugs

 

Pre-meal blood sugar generally reflects the lowest value of normal people's blood sugar and the lowest value of well-controlled blood sugar in diabetic patients, indicating the length of time of action of antidiabetic drugs.

 

  Pre-meal blood sugar control standard: 4.4-7.0mmol/L.

 

Nighttime blood sugar: tell you why fasting blood sugar is high

 

In order to distinguish the cause of high fasting blood sugar in the morning, it is necessary to measure nighttime blood sugar. Can monitor blood sugar at 0:00, 2:00, 4:00, and 6:00. If it is inconvenient, you can monitor blood sugar at 3 o'clock at night.

 

  If your blood sugar is low at night, that is, less than 3.9 mmol/L, it means that the reason for your high fasting blood sugar is rebound hyperglycemia after hypoglycemia, and you need to reduce your evening dose.

 

  If there is no hypoglycemia at night, it means that the reason for your high fasting blood sugar is the secretion of glucagon hormone in the morning, and you need to increase the dose at night.

 

  Nighttime blood sugar: No hypoglycemia occurred.

 

  Blood glucose 2 hours after a meal: Checking the effect of treatment

 

One hour after a meal is often the time when blood sugar is highest, and it is also the time when B cells are most stimulated to secrete insulin. Insulin will lower blood sugar. By 2 hours after a meal, a normal person's blood sugar has generally returned to the fasting level, which should be at least reduced to 7.8mmol. /L or less.

 

  People with impaired glucose tolerance or diabetes will definitely not be able to reach this level of blood sugar 2 hours after a meal. By monitoring whether blood sugar reaches normal levels during this period, the effectiveness of diabetes treatment can be evaluated.

 

  Postprandial blood sugar should be monitored after three meals. You cannot just measure blood sugar after a certain meal, because blood sugar changes after each meal are different. Normal blood sugar after one meal does not mean that blood sugar after other meals is also normal.

 

  Blood sugar 2 hours after a meal: 4.4-10.0 mmol/L.

 

  Random Blood Sugar: Capturing the Moment of Low Blood Sugar

 

When hypoglycemia occurs, a lot of glucagon hormones in the body are immediately released, and blood sugar will rise in about 10 minutes, and it will be much higher than usual levels.

  When you suspect that you have hypoglycemia, you should measure your blood sugar in time to capture the moment of hypoglycemia. If the test is late, normal blood sugar or hyperglycemia may occur. At this time, it is not clear whether it is a hyperglycemic reaction after hypoglycemia or continued hyperglycemia. The treatments for these two situations are completely opposite. Without measuring blood sugar, there will be no basis for changing the treatment plan.

 

  Random blood sugar can also observe the impact of special circumstances on blood sugar. For example, when you eat more, eat less, eat special foods, drink alcohol, be tired, exercise strenuously, get sick, have mood changes, or have menstrual periods, what impact will it have on your blood sugar and how much of an impact will it have? Then you will know what you can and cannot do. , adjust your life scientifically.

  Random blood sugar: no more than 11.1mmol/L.

 

  Monitoring blood sugar is not a "test", it is just a test. There is no "good" or "bad" blood sugar value, it is just a value. When faced with a high blood sugar value, what you should be thinking about is "What do I need to do about it?"
