Drawing Up and Giving Insulin
Contents
1. Swelling of the skin or hypertrophy occurs when too many injections are given in one area over a period of months to years which causes scarring of the fat tissue People like to give shots in the same spot because nerve endings pain are dulled after a few injections You can inject insulin into the body anywhere there is enough fat under the skin Usually there isn t fat over the joints and bones so these areas are not used If swelling or lumpiness in an area does occur you should not give further injections in that area until the swelling is gone This may take several months and varies for different people The swelling will alter the uptake of insulin P Skin Dents atrophy or lipoatrophy You may develop dents at the injection site This is different from skin swelling and is due to a loss of fat in that place Denting is now very rare when human insulin is used When dents do occur it is possible to help them go away To inject into the dented area pick the skin up at the side of the dent Slide the needle under the center of the dent If you inject human insulin four times in a row each week the dent will gradually go away This may take several weeks 8 Plugged Needle Occasionally a small piece of fat or the insulin will plug the end of the needle during the injection Sometimes it is possible to pull out the needle a little and then push the needle back into a slightly different place If you still2.

9. may be injecting into an area with too little fat and depositing the insulin into muscle This changes the insulin action Consider giving shots in an area with more fat tissue Injecting Insulin Into Muscle If a person is very thin or very muscular there may be little fat under the skin Injections may go into the underlying muscle causing more rapid absorption of insulin and low blood sugar There may then be less insulin to act later in the day resulting in high blood sugar Injections into the muscle are most likely to occur if the syringe is held at a 90 angle to the body or if the skin is not pinched prior to the injection This is common when a thin person gives their own shot and reaches over to the 90 Chapter 9 Drawing Up and Giving Insulin other arm and injects Instead the fat on the arm can be rolled on the back of a chair or on the knee and then the shot given in the rolled fat Sometimes extra pain will occur when shots go into muscle but this is not always the case Thus the pain is NOT a good indicator of shots given into muscle If injecting into muscle is a problem it may be wise to pull the skin away from the muscle and insert the needle into the tent below while still holding the pinch of skin Since the entire pinch is not being held just the upper tip the insulin should not leak back This technique can be taught by your diabetes nurse Occasionally it may be helpful to give an inject
