Vaginal infection caused by numerous bacteria that change the vaginal bacterial flora usual balance.
It is more common in women aged between 15 and 45 years old.
There is no clear cause for this condition, although factors that favour its appearance have been described: having a new sexual partner, multiple sexual partners, vaginal douches, etc.
It is not considered a sexually transmitted disease.
Very often the affected woman does not present any symptoms. When symptoms appear, they usually do so in a whitish or grey vaginal discharge with a very unpleasant fish-like smell. The fish-like smell intensifies when having sexual relations. It may be accompanied by itching in the genital region and a burning sensation when urinating.
It is diagnosed by means of clinical history and a gynaecological examination, where a sample of vaginal secretions will be collected to analyse it in the lab.
Treatment is based on administering oral antibiotics or as a vaginal gel. There is no need to treat an asymptomatic sexual partner.
It is not considered a medical urgency, but visiting a gynaecologist is strongly recommended once suspected.
