As science continues to advance, people have more methods and instruments about accurately keeping track of their health conditions. Blood sugar measurement is a very common test to determine whether a person is suffering from diabetes or high blood pressure. But why do you need to fast to measure your blood sugar? First of all, it is to eliminate the possibility that after eating food, the food is digested causing the blood sugar in the body to rise and thus misjudging the situation.

Because nowadays the diet has gotten better, people are starting to overeat and don't care about their dietary concerns. As a result, they suffer from a number of diet-related ailments, and diabetes is one of the more common cases. We should all know that the essence of diabetes is that the insulin in the body is abnormal, so it can not convert the glucose from food into the nutrients needed by the cells. It makes the blood sugar concentration in the body high, but the cells are unable to absorb it, making the cells keep passing the idea of the brain to eat, and it also creates the situation of eating a lot but being thin. So when we test diabetic patients in the case of patients did not eat, if the body's blood glucose concentration is higher than the normal concentration so can determine whether the diabetes, but if it is not fasting, the body's blood glucose is certainly higher than the normal concentration of the blood glucose, so blood glucose measurement must be fasting.

From the above, we can clearly know how serious the disease of diabetes is, if we are because of their own eating habits and thus triggered diabetes, it is very painful. So we must pay attention to our eating habits in our daily life, and we must not overeat. And we must pay more attention to health news, more to see if they have some of the characteristics of the disease to timely medical examination.

Lastly, I would like to tell you that every request and every medical advice from the doctor has a rigorous scientific connotation and deeper meaning. We can't judge whether it's reasonable or not based on our own subjective consciousness. Just like fasting before testing blood glucose, the doctor doesn't want us to eat, but rather a kind reminder for fear of giving us a wrong judgment.
