Site rotation is an important component of insulin therapy, especially for people with diabetes who inject three or more times a day. Proper site rotation may result in more consistent insulin absorption and minimize development of lipohypertrophy/lipodystrophy.Injection into lipodystrophied sites, results in an erratic absorption of the drug, leading to glycaemic variability making it difficult to achieve suitable metabolic control.Annual examination of injection site is recommended for evidence of lipodystrophy.

What is lipohypertrophy?
Lipohypertrophy is an abnormal accumulation of fat underneath the surface of the skin. It’s most commonly seen in people with type 1 diabetes. In fact, up to 50 percent of people with type 1 diabetes experience it at some point.Repeated insulin injections in the same location can cause fat and scar tissue to accumulate.

Symptoms of lipohypertrophy

The main symptom of lipohypertrophy is the development of raised areas under the skin. These areas may have the following characteristics:

- small and hard or large and rubbery patches

- surface area over 1 inch in diameter

- a firmer feel than elsewhere on the body
