Can drinking too much soda make a womens vagina smell? would moderation help? or should you cut soda out all together?

Bacterial vaginosis?: No soda, any other drink, or diet can have any effect on vaginal odor. The main cause is bacterial vaginosis, an overgrowth of mostly normal bacteria. BV is often triggered by STDs, and sometimes by sex itself. And some STDs, especially trichomonas, cause the same odor. Do not try to treat yourself: you need to be professionally evaluated to confirm the diagnosis and check for STDs. Good luck.

Uncertain: Sugar intake (in soda) can effect yeast but it should not have a bad odor. Lots of sugar might effect bacterial vaginosis.
