I'd use due to/from

Student or Learner
Hello.
She fell down ______ anemia in a crowded train.
What do you put in the blank to complete this sentence? Can I put "for" there?
Thank you.
I'd use due to/from
Does "for" make the sentence awkward?
- fall down from anemia
- collapse from anemia
These two sounds good, and they mean the same thing, don't they?
She fell down ______ anemia in a crowded train.
Any way you slice it, this seems like an awkward sentence.
‘due to’, ‘from’, ‘because of’, or anything else I can think of makes it ambiguous. It could sound like the crowded train has the anemia. (though we know this couldn’t happen unless she tripped over a lot of anemic people!)
What about 'stricken with'?
