How long can one live with AIDS?

People with AIDS who don't take medication only live about 3 years, even less if they get a dangerous infection. But HIV can still be treated at this stage.

Life expectancy today is about 70 years, if they're being treated and keeping healthy. 

AIDS or HIV

You can live a long time with HIV, once it's developed to full blown AIDS not very long

Until you die.

Easy.

AIDS or HIV? I know people who have been living with HIV for 40 years. Once it moves into AIDS, it's more serious, but there are some very good treatments for it now. 

My friend died a week after he was diagnosed.

So there's your answer.

With appropriate medication people living with AIDS can live a normal lifespan.

It's no established timeline it's all dependant on which opportunistic infection or disease they succumb to from having a compromised immune system.
