What is Thrush in Pregnancy?
Thrush is a common yeast infection caused by an overgrowth of Candida, a fungus that naturally lives in the vagina in small amounts. Pregnancy hormones increase glucose levels in vaginal secretions, making thrush more common during pregnancy than at other times.
It typically causes itching, soreness, and a thick, white discharge often described as looking like cottage cheese. It's not harmful to the baby, but it can be uncomfortable and is worth treating for your own comfort.

- 2Avoid scented soaps and washes.These can disrupt the natural balance and worsen symptoms.
- 3Wear breathable cotton underwear.This helps reduce moisture build-up that can encourage yeast overgrowth.
