In patients who are sensitive to insulin, 1U of insulin can reduce blood sugar by 2.22~3.33mmol/L. Under normal circumstances, 1U of insulin can reduce 2 to 3g of glucose, and the molecular weight of glucose is 180, which can reduce blood sugar by 11.1 to 16.6mmol/L.
The blood volume of an adult accounts for about 7% to 8% of the body weight, that is, a person weighing 60kg, based on the blood volume of 5L (5000ml), 1U of insulin can digest 10 to 15g of monosaccharides. When you need to eat 1 tael (50g) of staple food due to work, you need to add 5U of insulin, that is, 1U of insulin can lower the blood sugar (glucose) increased by 10g of staple food.
