Insulin is injected into the subcutaneous layer (fat layer) just underneath the skin. This is done by pinching up the skin and injecting the syringe or pen on an angle. For pen insulin this should be a 90 degree angle and for syringes a 45 degree angle.
Insulin injection site rotation is extremely important in good diabetes management. It will help prevent lumps from forming under the skin and ensure good insulin absorption. If insulin is injected into the same spot repeatedly, fatty lumps will form. This is called Lipohypertrophy.
Lipohypertrophy means that insulin will not be absorbed in the same way as healthy tissue and can lead to increased insulin doses and greater variation in BGLs.
To prevent lipohypertrophy from developing, it is important to rotate injection sites.
Sites that can be used for insulin injections include stomach, hips, arms and legs.
Below are examples of rotation strategies for the stomach area. Like the stomach area, these systems can be used for the arms, legs and hips as well
