I don’t know how common it is for people to die from lupus, but it looks like lung problems are common.

Like I said, i have seen plenty of people with Lupus. Off the top of my head I dont remember anyone dying from it and I do have a pretty clear memory of every patient I had that died. In 40 years I would estimate that I saw well over 100,000 patients. If that helps.
I dont know how common it is for people to die from lupus, but it looks like lung problems are common.
And deadly. When I was recently back in my hometown in Alabama, my cousin told me that one of my girlfriends from 1967 had died last year. Finally managed to track down her younger sister in a nearby town to give my condolences and find out what happened. Turns out she had Lupus and died from lung and kidney complications.
She was 68.
