PROBLEM: Injecting into a muscle or a very thin layer of skin changes the absorption rate and action of the insulin.
SOLUTION: Insulin should be injected into the fatty layer of skin. Try to choose an injection site with enough fat to “pinch up an inch” at the site, and inject into the center of the “pinched up” area. Do not release the skin until the insulin is fully injected at a 90° angle. If you are very thin, you can inject with a regular size insulin needle at a 45° angle.
PROBLEM: Frequent rotation of insulin sites can alter the absorption and action of the insulin dose injected.
SOLUTION: The current recommendation is to rotate injections within the abdomen, the site which gives the most consistent absorption. If you need several injections each day, you should consult with your health professional to choose appropriate alternate sites. Then, it is advisable to use the same alternate site at the same time of day, and rotate within each site.
PROBLEM: Injecting into a thigh or arm before exercise can cause a very low blood sugar.
SOLUTION: Inject into the abdomen.
