If you are diabetic, then taking hypoglycemic medication the day before the fasting blood sugar measurement can make the blood glucose concentration lower.
Fasting blood glucose is the main diagnostic method for diabetes and is diagnosed when venous blood is measured at a level of 7 mmol/l or greater when accompanied by symptoms of diabetes.
Fasting blood glucose is also a common way of monitoring blood glucose levels during diabetes treatment. Taking medication can also have an effect on blood glucose levels, for example, taking hypoglycemic medication regularly over a long period of time can lower the fasting blood glucose level. The most common hypoglycemic drugs used in the clinic are metformin, dagliflozin, repaglinide, glipizide and so on.
Fasting blood glucose also refers to the interval of 8~10 hours without eating any food, and measured a blood glucose value, which can effectively avoid the impact of food factors on blood glucose.
In order to effectively control blood glucose, it is important to take standardized medication under the guidance of a doctor to avoid the occurrence of too low or too high blood glucose.
