Thanks for writing in.
It seems your sister has excessive perspiration. This can be due to anxiety
or improper control of diabetes
. Her sugars need to be rechecked and maintained in the normal range. She needs to stop worrying as that can lead to excessive stickiness as such. I think you'd be better off seeing the person who is managing her diabetes, her general physician or diabetologist
, whichever of the two would know her case the best.
Hope this helps
