Hi
@fifi23
Virtual Hug for you
And great point made by
@Guzzler
and as for the smell of sweat, not been on insulin, so can't say,
but i've not noticed much difference since DX ( T2D..diet + Met)
( i understand that's not the question, but i just wonder if maybe your just more sensitive to the smell at the moment..? )
Being a sweaty male, i'm blessed that my phereonomes seem to appeal to my missus (go figure

)
but she will occasionally mention i'm not 'quite' so sweet smelling, now and again.
nothing had changed i am aware of, same soap, bathing experience, deodorants, etc.
so we must all go through phases where body odours are more noticeable.
perhaps through foods intaken
hence why i ask if it's possible your just 'heightened' or 'clearer' in sensory perceptions for any reason.
probably isn't, but never hurts to eliminate other possible reasons.
Good luck finding resolution..
( i know i can be embarrassed if i catch a whiff of myself, and no deodorant is available.
hate to think how annoying that would be, if it was a constant, regardless of personal hygiene / deodorants.)
