What is Vaginal thrush?
Vaginal thrush is a common fungal infection caused by an overgrowth of yeast that naturally lives in the vagina. It causes itching, soreness, and a thick, white discharge, often described as resembling cottage cheese, along with discomfort during sex or urination.
It's not classed as a sexually transmitted infection, though it can occasionally be triggered by sexual activity. Common triggers include antibiotics, pregnancy, diabetes, and tight or non-breathable clothing.

Practical steps
Take these self-care steps
These measures can help ease symptoms, support recovery, and reduce the chance of things worsening — but they don't replace medical advice if symptoms are severe or persistent.
- 1Use an over-the-counter antifungal treatment.Pharmacy treatments, available as creams, pessaries, or tablets, are usually effective for straightforward cases.
- 2Wear breathable, cotton underwear.This helps reduce moisture build-up that encourages yeast overgrowth.
- 3Avoid scented soaps and douches.These can disrupt the natural balance of the vagina and worsen irritation.
- 4Wipe front to back.This simple habit helps prevent introducing bacteria or yeast from other areas.
- 5Complete the full treatment course.Even if symptoms improve quickly, finishing the recommended course helps fully clear the infection.

BarnMD Bottom Line
Vaginal thrush is common and usually clears up quickly with over-the-counter antifungal treatment, though recurrent thrush is worth discussing with your GP.
If this is your first episode of suspected thrush, it's worth confirming the diagnosis with a pharmacist or GP before self-treating.
