Second, the theory is four times a day. The hypoglycemic effect of three meals, glucose absorption during the period and glucose absorption at night.
Two injections a day depend on the different action time of short-acting and medium-acting premixed insulin. The hypoglycemic effect of breakfast lies in the short-term effect of premixing, the medium-term effect of premixing at lunch, the short-term effect of premixing at dinner and the medium-term effect of premixing at night.
"Blood sugar is not normal at all when there is no injection at noon" is a moderate lack of premixed insulin injection in the morning. Need to be adjusted.
Ask a doctor for guidance and don't change yourself, otherwise hypoglycemia will occur.
