A Biologist told me that the water molecule is too small to cause an immune reaction. Is he correct?

Do you think 'water allergy' is a thing?

    Daily Mail? Social News Daily? Who cares what they write? Find an article from reputable organization.

    BTW:
    "It is sometimes described as an allergy, although it is not a true histamine-releasing allergic reaction like some other forms of urticaria."

    Here we go again.

    You are 70% water. An allergy to water is like an allergy to nitrogen.

    I confirm.
    You can not be allergic to water.
    But some peoples can be affected (like if they where allergic) by external water on their skin.

    So this condition is fake? https://en.wikipedia.org/wiki/Aquagenic_urticaria

    Some people with this condition cannot drink plain water or it makes their throat close.

    It is not an allergy.

    Just been chatting with a nurse who brought me my pain relief medication an happen to mention the chat SciForum was a pain distraction while I'm chatting

    Mentioned about people being allergic to water

    "Oh we had a patient with that short time ago. When he was admitted brought with him water for consumption and for ablutions"

    Apparently the water he brought was from a well on his property

    Then she was called away to another patient

    Don't know if I'll be in a position to get more (non personal) details

    Don't think it was the water allergy which brought him in though

    01:00 am Friday 10 June Ret Nurse Michael reporting from the other side of the fence. Medication kicking in, time I try to go back to sleep

    Orange juice and milk aren't water. That's why she can drink those. When water is mixed with other things, it becomes a new compound.

    You will find all sorts of such ignorant information like that out there.

    Diet Coke is 99% water. That means a 500g bottle of Diet Coke has them consuming 495g of water - a little over a pound.

    If a 1cc thimbleful of water can give them urticaria then a 500g bottle of coke - where 495g of it is water - is certainly going to be a problem.


    Stop posting this crap. Go find a reputable source.

    Here's a case report of a person with Aquagenic Urticaria who was internally allergic to water like Heidi is:

    https://ncbi.nlm.nih.gov/pmc/articles/PMC5438944/

    ''He also complained of pruritic erythematous changes, with swelling of the lips and oral cavity, after drinking water. ''

    Not as severe as Heidi's case but it's not controversial that allergies can have varying severities between each person.

    Yeah, that's about the whole of it. He claims to be a med student↗, but apparently had never heard of JAMA↗, which he considers "conspiracy hogwash".

    False pretenses are ubiquitous online; there are various purposes motivating such behavior, but the common result is the propagation of uncertainty.

    Meanwhile, I want to know who this mysterious biologist is. You know, the one mentioned in the thread title.

    • • •​

    You're supposed to be a med student, remember? You're not doing a very good job of pretending.

    You might want to tell whoever put you up to it that you failed. Tell them you weren't smart enough to do the job, and achieved a reputation as a crackpot not even worth laughing at.

    Or go ahead and tell us nobody put you up to it; that's an even worse prospect, but not unbelievable. Lots of people think they're clever; perhaps the newest thing about your routine is its manner of failure.

    When other people have to parse definitions of "compound" for the med student who doesn't recognize the Journals of the American Medical Association, you're doing it wrong.

    Then I'm interested in your explanation on how these people can drink other (non water) drinks but cannot drink plain water.

    Well, you could start with the paper you provided↗, but maybe you don't actually understand what it says.

    See the "Discussion" section of the paper: "The pathogenesis is still unclear, but the interaction of water with unknown components in the epidermis or dermis might cause histamine release from sensitized dermal mast cells …"; "Mast cells are concentrated around the blood vessels of normal dermis, with one to three cells per cross-sectional vessel profile, but in this patient there were slightly increased numbers of mast cells around blood vessels."

    The paper does not describe an allergy.

    Ballocks. Learn the difference between a compound and a mixture. My son learnt this at school in his very first chemistry lesson, at the age of 9 or 10.

    I’d stick to disappearing people and exploding thymus glands, Frank/Faceurchin.
