Lipodystrophy is a medical condition characterized by abnormal or degenerative conditions of the body's adipose tissue. ("Lipo" is Greek for "fat", and "dystrophy" is Greek for "abnormal or degenerative condition".) A more specific term, lipoatrophy, is used when describing the loss of fat from one area (usually the face). This condition is also characterized by a lack of circulating leptin which may lead to osteosclerosis.

Types
Lipodystrophy can be divided into the following types:[1]:495–7
-
- Congenital lipodystrophies
-
- Congenital generalized lipodystrophy (Beradinelli-Seip syndrome)
- Familial partial lipodystrophy
- Acquired lipodystrophy
-
- Acquired partial lipodystrophy (Barraquer-Simons syndrome)
- Acquired generalized lipodystrophy
- Centrifugal abdominal lipodystrophy (Lipodystrophia centrifugalis abdominalis infantilis)
- Lipoatrophia annularis (Ferreira-Marques lipoatrophia)
- Localized lipodystrophy
- HIV-associated lipodystrophy
Insulin injections
Lua error in package.lua at line 80: module 'strict' not found. A lipodystrophy can be a lump or small dent in the skin that forms when a person performs injections repeatedly in the same spot. These types of lipodystrophies are harmless and can be avoided by changing (rotating) the locations of injections. For those with diabetes, using purified insulins may also help.
One of the side-effects of lipodystrophy is the rejection of the injected medication, the slowing down of the absorption of the medication, or trauma that can cause bleeding that, in turn, will reject the medication. In any of these scenarios, the dosage of the medication, such as insulin for diabetics, becomes impossible to gauge correctly and the treatment of the disease for which the medication is administered is impaired, thereby allowing the medical condition to worsen.
In some cases, rotation of the injection sites may not be enough to prevent lipodystrophy.
Antiretroviral drugs

Lipodystrophies can be a possible side effect of antiretroviral drugs. Other lipodystrophies manifest as lipid redistribution, with excess, or lack of, fat in various regions of the body. These include, but are not limited to, having sunken cheeks and/or "humps" on the back or back of the neck (also referred to as buffalo hump)[2] which also exhibits due to excess cortisol. Lipoatrophy is most commonly seen in patients treated with thymidine analogue nucleoside reverse transcriptase inhibitors [3] like zidovudine (AZT) and stavudine (d4T).[4]
Hereditary forms
Lipodystrophy can be caused by metabolic abnormalities due to genetic issues. These are often characterized by insulin resistance and are associated with metabolic syndrome.
Patient Foundation
Lipodystrophy United is a Non-Profit Organization created by lipodystrophy patients to provide community support and awareness.
