The adjustment of insulin dose should be based on the results of multiple blood glucose monitoring and combined with the patient's age, diet, exercise, medication, etc. Here are a few things to keep in mind:

(1) The dose of insulin must be adjusted under the premise that the patient's diet, exercise and mood remain relatively stable.

(2) After 2 ~ 3 days of initial estimated dose observation, adjust the blood glucose level every 3 ~ 4 days according to the blood glucose level on an empty stomach, two hours after three meals, before bedtime, and at 3 a.m., until the blood glucose control goal is reached. Generally, the basal dose is adjusted first, and after the fasting blood glucose reaches the standard, the mealtime dose is adjusted for postprandial blood glucose.

(3)When fasting blood glucose or preprandial blood glucose is 3 ~ 5 mmol/L, the insulin dose is reduced by 2 ~ 3 U; At 5 ~ 7 mmol/L, insulin does not increase or decrease; Above 7 mmol/L, increase insulin by 1 unit for every 1 mmol/L increase. For a postprandial blood glucose > 10 mmol/L, increase insulin by 1 unit for every 2 mmol/L increase.

Note: Do not adjust too much each time to prevent severe hypoglycemia or large fluctuations in blood sugar.

(4) In some special circumstances, temporary adjustments are required.

For example, in the case of an infected fever, the insulin dose needs to be increased; Acute gastroenteritis, vomiting and diarrhea, loss of appetite, need to reduce insulin dosage as appropriate; In addition, pregnant women with diabetes need to increase their insulin dose later in pregnancy and reduce their insulin dose once labor is over.

(5) When patients have hyperglycemia or hypoglycemia, do not only think about adjusting the dosage of insulin, but should analyze in detail whether there are other factors that interfere with glucose metabolism (such as drugs, sleep, infection factors, etc.).

(6) High fasting blood glucose, adjust insulin dosage, pay attention to distinguish between dawn phenomenon and Su Mujie phenomenon:

Sumujie's phenomenon is caused by nocturnal hypoglycemia, which requires a reduction in the dose of insulin at bedtime;

The dawn phenomenon is that diabetic patients at about 4 o'clock in the dawn due to the peak secretion of various hormones that have the effect of raising blood sugar in the human body, if the night medication is not enough or too early, resulting in the drug power can not reach the morning will lead to fasting hyperglycemia in the morning, in this case, it is necessary to increase the amount of insulin before bedtime.
