What is the difference?
Chlamydia vs Gonorrhoea
Chlamydia and gonorrhoea are both common bacterial STIs, often tested for together and often silent, so they are easy to confuse. They are caused by different bacteria, are treated with different antibiotics, and gonorrhoea raises particular concern about antibiotic resistance.
General information, not medical advice. For advice about your own situation, talk to a clinician, pharmacist or sexual health clinic.
Chlamydia
Chlamydia is a common bacterial STI that often causes no symptoms and is easily cured with antibiotics once it has been found through testing.
Full entryGonorrhoea
Gonorrhoea is a bacterial STI that can infect the genitals, rectum and throat, and is treated with antibiotics, although resistant strains are a growing concern.
Full entrySide by side
In short
Different bacteria, similar story: both are often silent and both are curable. Regular testing, especially after a new partner, is the only reliable way to know.
What they have in common
Both are passed on through vaginal, anal or oral sex without a condom, are found with the same urine test or swab, can lead to pelvic inflammatory disease and fertility problems if untreated, and both need partners to be tested too.

- Bacterial vaginosisvsThrushA fishy smell points more towards BV, itching more towards thrush, but symptoms overlap, so it is worth getting them checked by a pharmacist, doctor or sexual health clinic.
