Why it matters
Bacterial vaginosis and thrush are the two most common causes of vaginal symptoms, and they're easily mixed up — but they're completely different. Thrush is a yeast overgrowth; BV is a bacterial imbalance. Crucially, they need different treatments: antifungals for thrush, antibiotics for BV. Treating the wrong one won't work and can delay relief.
So telling them apart (or getting them tested) actually matters for getting better quickly.
The key differences
Thrush typically causes intense itching, a thick white 'cottage cheese' discharge, and redness or soreness, usually without much smell. BV typically causes a thin, greyish discharge with a fishy odour (often worse after sex), and usually little or no itching.
As a rough guide: itchy and thick, think thrush; smelly and thin, think BV. But symptoms overlap, and you can even have both at once, so this isn't foolproof.
When to get it checked
See a GP rather than guessing if it's your first episode, if over-the-counter thrush treatment hasn't worked, if symptoms keep coming back, if you're pregnant, or if you have pain, fever, or unusual bleeding. A simple swab can confirm exactly what's going on so you get the right treatment first time.
If you're not sure which you have, a telehealth consult can help sort it out and arrange testing or the correct treatment for you.
