HIV and Lipodystrophy

What Is Lipodystrophy?
Lipodystrophy refers to the changes in body fat that affect some people with HIV. Lipodystrophy can include:
What Causes Lipodystrophy?
The exact cause of lipodystrophy is unknown. It may be due to HIV infection or medicines used to treat HIV.
Other risk factors for lipodystrophy include:
Although more research is needed to prove that there is a link between HIV medicines and lipodystrophy, some HIV medicines have been associated with the condition. While lipodystrophy can't be cured, switching HIV medicines may help. Newer HIV medicines are less likely to cause lipodystrophy than HIV medicines developed in the past.
Many people with HIV never develop lipodystrophy.
What Parts of the Body Are Affected by Lipodystrophy?
Fat buildup (also called lipohypertrophy) can occur:
Fat loss (also called lipoatrophy) tends to occur:
A person with HIV can have fat loss or fat buildup or both. Whether the changes are noticeable or not depends on the degree of fat loss or fat buildup. See images of fat buildup around the neck and fat loss on the face and leg.
Is Lipodystrophy a Serious Health Problem?
It can be. Too much fat gain in the abdominal cavity can increase the risk of heart attack and diabetes.
Fat gain in the breasts can be painful. Buffalo humps may cause headaches and problems with breathing.
The changes in appearance caused by lipodystrophy can be upsetting and affect a person's self-esteem. Because of lipodystrophy, a person may decide to stop taking HIV medicines. However, the decision to stop taking HIV medicines (or cut down on the dose of a medicine) should be made only in consultation with a health care provider. Stopping HIV medicines allows HIV to multiply and damage the immune system, which increases the risk of HIV-related infections and cancer. Stopping HIV medicines also increases the risk of drug resistance.
Can Lipodystrophy Be Cured?
Unfortunately, there isn't a cure for lipodystrophy. More research is needed to understand the cause of lipodystrophy in people with HIV and to find a cure for the condition. However, there are ways to manage lipodystrophy.
In some people, changing HIV medicines may lessen the effects of lipodystrophy. Newer HIV medicines are less likely to cause lipodystrophy than HIV medicines developed in the past.
But, if you are taking HIV medicines, do NOT cut down on, skip, or stop taking your medicines unless your health care provider tells you to.
Liposuction (surgical removal of fat) is sometimes used to reduce a buffalo hump. Fat or a fat-like substance can be used as a filler for fat loss in the face. The filler is injected in the cheeks or around the eyes and mouth.
Medicines may help lessen the effects of lipodystrophy. For example, tesamorelin (brand name: Egrifta) is a medicine used to reduce the buildup of abdominal fat due to lipodystrophy.
A healthy diet and daily exercise may help to build muscle and reduce fat buildup.
