Can kombucha affect kidneys?

[Guest guest]

Hello folks,

Having a few problems here in texas....Couple of weeks ago, I

passed a bloody squiggly thing in urine, and now I have a kidney

stone...The doc told me I also have a kidney infection....Nothing

serious mind you...but I got to know, if kefir and kombucha might be

doing me some harm...My wife also has complained of her kidneys hurting

once in awhile.....We love our kefir and kombucha....Has anyone had

similiar problems....I drink lots of water....Could this just be

something that would have happen anyway.....Wife has ordered me to stop

all intake until we get to the bottom of this....Thirsty in tx...ron

and vivian in leander tx
