Blood Sugar in Our Body and Diabetes

Blood sugar mainly refers to the blood glucose in the body. For normal persons, the level of blood sugar is steady. After meal, the level of blood sugar will be a little higher, which will not be higher than 180mg/dl. The FBG( fasting blood sugar) is steady relatively, which is 70-110mg/dl(3.9-6.1mmol/L). All the energy the body needs comes from glucose. So the blood sugar must be enough so that it can meet the need of the body.
The normal range of FBG is 80 to 120 mg%. If it is more than 130, people will suffer high blood sugar. If it is less than 70, people will suffer from low blood glucose. Long time hunger, continuous strenuous work, etc can lead to low blood sugar. At this time, brain tissue will firstly realize it and then people will have dizziness, heart beating faster, hunger and so on.
Sugar is really a necessity which can be gained from grains, fruit and vegetables. After digestion, the sugar will be transformed into monose, and so on and then into blood. It is the source of energy. If it can not be exhausted, it will store in the liver or muscles. If it is too much, sugar will become fat.
For diabetes patients, high blood sugar is the main symptom, which is caused by the insufficiency of insulin secretion. If low blood sugar takes place, it may even threaten diabetics’ life. So controlling blood sugar is very important.
