The dosage of insulin for diabetes varies depending on the person. Generally speaking, it is multiplied by a factor of 0.4-0.8 according to the body weight. For example, if a diabetic patient weighs 60 kg, he can multiply this factor by 0.5. 5 times 6 is 30 units, which should be divided into 30 units a day, and the distribution ratio of dosage will be different according to the use of different insulins. For example, if you use premixed 30 and menthol 30, it will be divided equally into two parts, 15 units in the morning and 15 units in the evening. If the chosen solution is three short and one long, the long-acting insulin will take up half of the dose, and the large dose of three meals will be put in half, that is, the 30 will be divided into two parts, and the glycine will be played 15 units, and then the 15 units will be divided into three parts, 5 units in the morning, 5 units at noon and 5 units at night, so that the total will add up to 30 units. This is the calculation method only for the case of islet secretion insufficiency. When the patient still has insulin secretion function, the insulin dose is adjusted according to the insulin function, and it may decrease or increase. When the insulin resistance of a patient is very obvious, the insulin dose will be different and will be higher. Therefore, the dose of insulin varies according to different people, different islet function, and different degree of islet resistance.
