I'm looking for a medical metaphor. The idea is:
1) You normally consume something that is good and beneficial (air, water, some vital nutrient)
2) Then you get a disease or have a condition where that beneficial thing suddenly becomes poisonous or destructive to the body.
BTW, I'm not talking about excess... where excessive use of something becomes harmful (like water intoxication). I'm talking about a disease itself that fundametally alters the way your body operates.
What comes to mind when I say this?
