Sudden vaginal odour or unusual discharge — and you’re not sure why? 👇
First of all, this can happen more commonly than people realise, and it’s not always a sign that something is “wrong”.
In a healthy vaginal environment, we’re typically lactobacillus-dominant 🌿
These beneficial bacteria help keep the pH more acidic, which supports balance and protection.
But here’s what can shift things:
Even in a healthy system, there can be small amounts of other microbes present at all times — usually not causing any issues at all.
The problem starts when the environment changes:
⚖️ The vaginal pH becomes more alkaline
🌡️ The balance of bacteria shifts
📈 Certain microbes now have a better environment to grow
When that happens, those microbes can increase in number, take up more space, and become more active — which is when symptoms like:
👃 odour
💧 changes in discharge
can appear.
The key point: it’s not always about “new bacteria arriving” — it’s often about a shift in balance that was already there.
If you’re experiencing changes, it’s always worth getting it checked — because understanding the why helps guide the right support 🤝
