You may need to take one type of insulin or a combination of several types of insulin throughout the day. This depends on several lifestyle factors, diet and how well blood sugar controlled between meals.
Try not to inject your insulin in the exact same place in your body every time.
This is to prevent a condition called lipodystrophy. In lipodystrophy, fat under the skin breaks or builds up and forms lumps or indentations that can block insulin absorption.
The best places to inject insulin are the abdomen, front or side of the thighs, upper buttocks, and upper arms because of their higher fat content.
