What does green vaginal discharge mean, and when should it be medically assessed in Europe?

Green vaginal discharge explained: sexually transmitted infections (STIs), trichomoniasis, bacterial infection, pelvic inflammatory disease (PID), and testing criteria.

In this episode, we outline the most common causes of green discharge and how doctors distinguish infection from other vaginal conditions during an online consultation in the EU.

You’ll learn:

• Why green or yellow-green discharge often suggests infection

• Symptoms of trichomoniasis (frothy discharge, irritation, odour)

• How gonorrhoea or chlamydia may present

• When pelvic inflammatory disease may be suspected

• Differences from bacterial vaginosis or yeast infection

• Red flag symptoms such as pelvic pain, fever, bleeding between periods, or pain during sex

• Situations where treatment requests may be declined pending laboratory confirmation

We explain how doctors assess discharge colour, odour, sexual history, pregnancy risk, recurrence pattern, and associated symptoms before prescribing. Vaginal swabs or STI testing are usually required to confirm diagnosis and guide antibiotic selection.

This episode reflects the clinical standards used by Mobi Doctor, where women’s and sexual health consultations are reviewed by a registered physician in line with EU medical guidance.
