The bacterial vaginosis (BV) is one of the most common infections of the vagina, and in fact, according to medical data, it is estimated that around 30% of women suffer this type of infection once throughout her life, especially during the fertile age. The cause of its origin, for now, remains an unanswered question. It appears as a consequence of the increase of the vaginal pH, due to the proliferation of pathogenic organisms that alter the bacterial flora. Bacterial vaginosis, if not treated properly, can lead to gynecological and obstetric complications.

Although it may be an asymptomatic infection (does not produce obvious symptoms), the most common is to be accompanied by changes in flow, both in appearance (becomes more fluid, slightly thick), colored (white or gray) and smell (acquires a strong fishy smell, especially after sexual intercourse or in the days prior to menstruation).

In some cases, burning sensation may also occur when urinating or itching in the external area of the vagina. Among the risk factors are included from moisture in the area (for wearing tight clothes, for example), excessive sexual activity with multiple partners, douching, the excessive use of intimate hygiene products perfumed and even the snuff.


Doctors recommend treating bacterial vaginosis in women with symptoms, or in those without symptoms that have just undergone an abortion, a hysterectomy or are exposed to other STDs (to reduce the risk of infection). When the doctor prescribes antibiotics (metronidazole, clindamycin) can be by mouth (pills) or vaginal (gel, cream, ova), depending on the assessment of symptoms and the patient’s health status.

In some cases, different drugs may be combined. It should be noted that vaginosis is not an STD, so it is not necessary that the treatment be extended to the couple.


Although it can sometimes disappear without treatment, it is important not to underestimate the symptoms, since although it does not usually lead to complications, in some cases the risk of pelvic inflammatory disease may be present.

Some researchers have also pointed out that this infection may increase the risk of contracting sexually transmitted diseases. If it occurs during pregnancy, it can increase the risk of complications during pregnancy and childbirth (preterm delivery, spontaneous abortions).
