Medical treatment in 1700s Europe

[blueinkedfrost]

Any medical conditions from 1700s continental Europe where a wealthy person would have a better prognosis compared to a poor person?

I'm looking for a condition to kill off a poor middle aged woman, one where a wealthy woman of the same age would have been more likely to survive with period appropriate treatment. Until her illness and death, the woman was a labourer and quite physically active.
