Thrush: symptoms, causes & treatment

Thrush is a common yeast infection causing itching and discharge. It is easily treated with antifungal medicine — but recurrent thrush needs proper assessment.

Editorial information by Kaiser Khan. Not clinically reviewed.

Symptoms

  • Itching and soreness
  • Thick white discharge
  • Discomfort during sex or urination
  • Red, swollen vulva or penile irritation

Why it happens

Candida yeast overgrowth, often after antibiotics, during pregnancy, with diabetes, or when immunity is reduced. It is not classed as an STI but can pass between partners.

Treatment

Single-dose oral capsule or topical cream clears most thrush within days. Partners may need treatment if symptoms keep returning.

Self-care that helps

Avoid perfumed soaps; cotton underwear; complete the full course; do not use douches or harsh washes.

When to get help

Recurrent thrush (4+ times a year), symptoms under 16, pregnancy, or not improving after treatment — get reviewed.
