Vaginitis may be caused by any of the following infections or irritants:

  • Thrush a fungal infection that commonly affects the vagina
  • bacterial vaginosis a bacterial infection of the vagina
  • trichomoniasis a sexually transmitted infection (STI) caused by a tiny parasite
  • chemical irritation for example, from perfumed bubble bath, soap or fabric conditioner, or from spermicide (a chemical that kills sperm, sometimes found on condoms)
  • washing inside your vagina
  • chlamydia an STI caused by bacteria
  • genital herpes an STI caused by the herpes simplex virus

Vaginaldryness , itching or discomfort (particularly during sex) can also sometimes be caused by a fall in oestrogen levels after the menopause . This is called vaginal atrophy or atrophic vaginitis, and is due to the thinning of the vagina's lining.
