Overview
In this section you will get an overview of the condition and its relevance to your health.
Gardnerella vaginalis is a bacterium that is naturally present in small amounts in the vagina of many women. However, when the delicate balance of the vaginal flora is disrupted, this organism can multiply strongly and cause symptoms.
Gardnerella vaginalis is frequently associated with bacterial vaginosis. However, the mere detection of this bacterium does not automatically indicate disease — what matters is the presence of symptoms and the overall composition of the vaginal flora.
Whether and which therapy is suitable is assessed individually as part of a medical consultation -- also available online.
What is it?
Here you will learn what medically characterizes this condition and how it is defined.
Gardnerella vaginalis is an anaerobic bacterium that plays a central role in the development of bacterial vaginosis. It produces enzymes that displace the protective lactic acid bacteria and alter the acidic vaginal environment.
In a healthy state, lactobacilli dominate the vaginal flora. When Gardnerella vaginalis and other anaerobic bacteria multiply, the vaginal pH rises. This promotes the development of typical symptoms such as discharge and odor.
Important to note: Gardnerella vaginalis is not a classic sexually transmitted pathogen but can be promoted by sexual activity.

Causes
The following information explains which factors can contribute to the development of this condition.
The multiplication of Gardnerella vaginalis is promoted by various factors that disrupt the natural vaginal environment.
Disruption of the vaginal flora is the most important trigger. Causes can include frequent intimate washing, vaginal douching, or aggressive care products.
Sexual factors such as frequently changing partners or unprotected intercourse can influence the bacterial balance without constituting classic transmission.
Hormonal changes, such as during menstruation, pregnancy, or from hormonal contraception, can promote the growth of Gardnerella.
Other risk factors include:
- Smoking
- Copper IUD
- Previous bacterial vaginosis
Symptoms
This section describes the typical signs and symptoms you should watch for.
Not every woman with Gardnerella vaginalis develops symptoms. Many infections are asymptomatic.
Typical symptoms, when present, include:
- Thin, grayish-white vaginal discharge
- Fishy odor, especially after intercourse
- Mild burning or itching in the intimate area
Unlike a vaginal yeast infection, there is usually no severe itching, redness, or crumbly discharge.
Warning signs that require medical evaluation:
- Lower abdominal pain
- Fever
- Bleeding
- Symptoms during pregnancy

Diagnosis
Below you will learn how this condition is detected through medical examinations.
Diagnosis is made through a gynecological examination and a vaginal swab.
Typical findings include:
- Elevated vaginal pH
- Detection of Gardnerella vaginalis in the swab
- Presence of so-called clue cells
Important: The mere detection of Gardnerella vaginalis without symptoms does not necessarily require treatment.
During an online consultation, symptoms, previous findings, and test results can be evaluated. For typical symptoms, therapy can be recommended.
Treatment
Here the available therapy options and their modes of action are explained.
Treatment depends on the symptom profile and the extent of bacterial imbalance.
Metronidazole is the first-line treatment and can be used orally or locally. It is a prescription-only medication whose suitability is assessed by a doctor. Common side effects include nausea, abdominal discomfort, or a metallic taste.
Clindamycin is an effective alternative, particularly if metronidazole is not tolerated. It is usually applied locally as a vaginal cream.
Important notes:
- Alcohol should be avoided during metronidazole treatment.
- Routine partner treatment is generally not necessary.
For recurring infections, longer-term therapy or accompanying stabilization of the vaginal flora may be beneficial.
Prevention
This section provides guidance on prevention and reducing risk factors.
To prevent renewed proliferation of Gardnerella vaginalis, gentle care of the intimate area is essential.
Recommended measures include:
- Avoiding vaginal douching
- Using mild, pH-neutral intimate care products
- Using condoms with changing sexual partners
Individual medical advice can help identify and specifically reduce personal risk factors.

FAQ
Here you will find answers to frequently asked questions on this topic.
No, Gardnerella vaginalis is not considered a classic sexually transmitted disease. Sexual activity can promote its proliferation but is not the sole cause.
No, detection without symptoms usually does not require treatment. Therapy is appropriate when symptoms or bacterial vaginosis are present.
Yes, recurrences are possible, especially when predisposing factors are present. A stable vaginal flora can reduce the risk.
Yes, for typical symptoms, treatment can be initiated after medical review through an online consultation.
