If Mast Cells Degranulated In Response To H2O, How Long Would A Person Live?

[LisaL]

Would a person live long if the mast cells somehow trained to fire upon exposure to H2O molecules? This woman says she cannot even drink a sip of water without needing an Epi-pen injected into her yet in her pictures she is not hooked up to a bed being IV'd adrenaline and looks quite alive. 

 

& before anyone mentions 'Aquagenic Urticaria' yes I'm aware of it, but it does not affect drinking, since it's a reaction to water soluble allergens on the skin. This case presents itself as if she were allergic to peanuts and everything with water was replaced with peanut butter.
