BV and yeast infections get confused constantly, and treating the wrong one is why so many people feel stuck. Here is the honest, plain-English difference.
The quick difference
They can feel similar, but the classic signs differ. BV tends to bring a thin, grayish discharge and a distinct fishy odor, often stronger after sex, usually with little to no itch. A yeast infection tends to bring thick, white, clumpy discharge with intense itch and irritation, and usually no strong smell.
Why the cause is different
Both trace back to a disrupted vaginal environment, but from different directions. BV is an overgrowth of certain bacteria when protective Lactobacillus drop and pH rises. A yeast infection is an overgrowth of Candida. Because the cause differs, so does what helps, which is exactly why guessing wrong keeps the cycle going.
What helps each
Both share a common thread: a healthy, acidic pH kept in balance by Lactobacillus. That is why boric acid (which helps restore acidic pH and disrupt biofilms) and a daily vaginal probiotic (which helps replenish Lactobacillus) come up for recurrent forms of both. For the specifics, see boric acid for BV and boric acid for yeast infections.
Why you should confirm it
You genuinely cannot always tell BV and yeast apart by symptoms alone, and it is easy to be wrong, especially the first time or when things keep recurring. This is educational, not a diagnosis. A quick check with your healthcare provider confirms which one you are dealing with so you are not treating the wrong thing.
