Bacterial Vaginosis

Overview

Bacterial vaginosis is not a sexually transmitted infection, but it is more common in sexually active women. It is easily treated, though it can come back.

Symptoms

• Thin, white or grey vaginal discharge
• A fishy smell, often stronger after sex
• Mild itching or irritation
• Many women have no symptoms

Causes and risk factors

It happens when the normal balance of vaginal bacteria changes. Risk factors include douching, new or multiple sexual partners, and using scented soaps or products in the genital area.

Diagnosis

A doctor examines the discharge and may test a swab sample.

Treatment

It is treated with antibiotic tablets, gels or creams. Avoiding douching and perfumed products can help prevent it returning. Treatment is especially important during pregnancy.

When to see a doctor

See a doctor if you notice unusual discharge or smell, particularly if you are pregnant, have pelvic pain or fever.
