A hormone better
known for illicit use among athletes can help treat
troublesome complications from the AIDS virus, but with
potentially risky side effects, a small study found.

can affect other parts of the body, are harder to fix,
although a healthy diet and lots of exercise can help.
The study results
show that human growth hormone could be useful for HIV
patients with abdominal fat accumulations and normal blood
sugar levels, although it's "not a panacea," said

He called the
approach experimental and said new AIDS drugs with fewer
side effects are needed.
While there were
fewer side effects with lower doses, Emory University
AIDS expert Jeffrey Lennox called the results
"disappointing." He said they suggest that hormone
shots have limited use at best for treating
HIV-associated fat abnormalities.
