Insulin works best when injected into a layer of fat under the skin, above the muscle tissue. Several areas of the body have enough fat tissue under the skin for insulin injection. The abdomen, except for a 2-inch circle around the navel, is used most commonly. Another suitable area is the top and outer thighs. This is best used when you are in a sitting position. The backs of the upper arms, the hips, and the buttocks also work well. Some people, especially those with a large body size, have other options. For example, the lower back can also be a good injection site, as long as there is enough fat under the skin.
