You are not alone. Diabetes causes a wide range of horrible complications. Some are more obvious than others, such as blindness and amputation. But some complications are hardily mentioned and largely unknown by those who don't suffer from them. I am constantly learning about possible diabetic complications and I wanted to put all my knowledge in one place to share it with others. This page includes a basic explanation of the complication. For further information please ask your doctor, a medical professional or professional medical website.
Lipohypertrophy--is a medical term that refers to a lump under the skin caused by accumulation of extra fat at the site of many subcutaneous injections of insulin. It may be unsightly, mildly painful, and may change the timing or completeness of insulin action. It is a common, minor, chronic complication of diabetes mellitus.
How to avoid: To avoid lipohypertrophy, persons with diabetes who inject insulin daily for an extended period of time are advised to rotate their injections among several areas (usually upper, outer arms, outer thighs, abdomen below and around the umbilicus, and the upper parts of the buttocks. Lipohypertrophy usually will gradually disappear over months if injections in the area are avoided.
