Amy Winehouse diagnosed with emphysema

After collapsing in her London home last week, singer Amy Winehouse has been resting and undergoing tests in a London hospital. After a short-lived TB scare, doctors finally pinpointed her condition. She's been diagnosed with emphysema, in the very early stages. Emphysema is a lung condition that creates breathlessness and reduces a person's ability to be physically active.

Though there's no cure for emphysema, Winehouse's condition will likely be controlled by a smoking cessation program (smoking the main risk factor for emphysema), lung rehabilitation, and medications. The damage caused by emphysema is irreversible, but Winehouse's publicist insists she's in the earliest stage of the disease.

According to her father, Winehouse is eager to began rebuilding her health and has been following doctor's orders to the letter. Whether she's able to continue touring or not will depend on whether those doctors feel like she's up to the task.
