Insulin should be pushed slowly, and the site and type of insulin should be determined and the medication should be guided by the doctor. Insulin injection speed can be relatively fast, but the speed of pushing the needle should generally be slow, because insulin injection is a subcutaneous injection, if the speed of pushing the needle is too fast, it will directly affect the absorption and utilization of insulin, which is not conducive to blood glucose control. After insulin injection, you need to stay for a while, and then slowly pull out the needle. Insulin can be injected in different parts of the body, such as abdomen, buttocks, upper arms, thighs, etc. Different parts of the body, different types of insulin are used, and the speed of insulin absorption is not the same, so you should specify the type of insulin to be injected before you inject the insulin and then choose the corresponding parts. It is recommended that patients should be instructed by their doctors on the specific way of injecting insulin and should not inject on their own.
