Why does Fantine die in 'Les Misérables'?

It has been a long time since I read this, but I believe Fantine died from a combination of the ills of proverty, poor nutrition, no medical care. She fell into prostitution to earn money for Cosette's care, so it is very likely that she had one or more of the various venereal diseases.

Fantine: A girl from the village of Montreuil-sur-mer who goes to Paris to find work. There she falls in love with a dandy who leaves her suddenly and with child. She returns to her home village to find work and on the way entrusts her child, whom she calls Cosette, to a seemingly kind couple called the Thénardiers. The Thénardiers demand increasingly large sums of money to board the child and Fantine, who loses her job in the factory, must sell her hair and teeth to provide for her daughter. Eventually she becomes a prostitute and is arrested but is saved by Father Madeleine. She dies of illness before he can reunite her with Cosette.
