Inspired by this tale - https://www.thefreelibrary.com/JUST+ONE+CUP+OF+WATER+COULD+KILL+LITTLE+HEIDI%3B+Girl%27s+deadly+allergy...-a061152595
Let's say someone is so allergic to H2O that a sip of water will send them into anaphylactic shock, (requiring a shot of adrenaline every time they take a sip of water) and if they get IV'd with a drip, they react to the water being injected into their body (such as is the case with the link I posted above).
I'm not talking about a mere skin irritation that isn't actually an allergy (Aquagenic Urticaria - which doesn't affect drinking as it's a skin condition only), I'm talking a full on potentially life threatening allergy to the H2O molecule when it is ingested as well like in the story above.
Basically, every time the mast cell immunoglobulins (located outside of the cell, along its surface) saw H2O molecules, it'd cause the mast cells to degranulate and release histamine.
Is it plausible that a person would live so long as to get a news article made about them?
