Two completely seperate and unrelated events I'm sure.

According to this week's Popbitch mailout:

LA's current concentration camp look isn't
just the result of cocaine and eating disorders.
Everyone's doing Clenbuterol. Prescribed
as an asthma medication, Clenbuterol is
taken by body-builders and now weight-watchers
for its amazing fat-burning qualities.
The drug works by raising body temperature,
thereby burning more calories. But it's
only designed to be taken temporarily
and carefully. Ever wondered why celebrities
always seemed to be hospitalised for asthma,
dehydration and exhaustion?

And in a completely unrelated turn of events -

Nicole Richie had to be treated for dehydration on the set of The Simple Life which she is currently filming with bestie Paris. E reports:

Richie apparently felt ill, was examined by an on-set doctor and then taken to a nearby hospital. She received intravenous fluids for 15 minutes and was released.

"Nicole is home resting and will return to work this evening," her rep said in a statement. "We are proud of the weight that Nicole is gaining and her focus on her health."
