The main purpose of long-acting insulin at 10 p.m. is to inject long-acting insulin at a fixed time every day, which can effectively control fasting blood glucose the next morning and can maintain stable blood glucose throughout the whole day the next day. It is not necessary to inject at 10:00 p.m., but a fixed time every day is sufficient, so that the insulin level can be stabilized throughout the day. Long-acting insulin injections need to be chosen at a fixed point in time. If you choose to inject at 10:00 p.m., you should insist on injecting insulin at around 10:00 p.m. every day thereafter, which aims to stabilize insulin levels throughout the day. It can effectively control fasting blood glucose the next morning and can maintain stable blood glucose throughout the day the next day, and is not prone to hypoglycemia.
