How is lipodystrophy treated?

If you have lipodystrophy, talk to your health care provider about treatment options. Your health care provider may recommend that you switch to another HIV medicine.

There are ways to manage lipodystrophy. Making dietary changes and getting regular exercise may help to build muscle and reduce abdominal fat.

Liposuction (surgical removal of fat) and injectable facial fillers are sometimes used to treat lipodystrophy. There are also medicines that may help lessen the effects of lipodystrophy.
