Q. What is the importance of the glucose blood level for human health?

The glucose blood level (glycemia) must be kept normal if it is abnormally low there is not sufficient glucose to supply the energetic metabolism of the cells. If it is chronically and abnormally high it causes severe harm to the peripheral nerves, the retina, the skin, the kidneys and other important organs and it may predispose to cardiovascular diseases (acute, thrombosis, myocardial infarction, strokes, etc). If it is acutely too high medical emergencies like hyperglycemic hyperosmolar and the diabetic ketoacidosis state may occur.
