Recurrent BV and yeast infections
Bacterial vaginosis, vulvovaginal candidiasis
Chronic conditionBacterial vaginosis (BV) and yeast infections are the two most common causes of vaginal symptoms. Many women get them again and again, and recurrent cases need a confirmed diagnosis and a longer plan.

What happens
A healthy vagina is usually dominated by lactobacilli, bacteria that keep it acidic. In BV, other bacteria overgrow and form a sticky film that antibiotics don't always clear, so BV often comes back within months. A yeast infection is an overgrowth of Candida. Recurrent yeast infection means 3 or more in a year. Some recurrent cases are caused by less common species, such as Candida glabrata, which don't respond to the usual treatments. Itching and discharge can also come from other causes, such as skin conditions, low estrogen, or sexually transmitted infections, so self-diagnosis is often wrong.
Who gets it
BV is the most common vaginal condition in women of reproductive age. Douching, new or multiple sex partners, an untreated male partner, and smoking raise the risk. Yeast infections are more common with antibiotics, pregnancy, high-estrogen birth control, uncontrolled diabetes, and a weakened immune system.
Signs worth getting checked
- Thin gray or white discharge with a fishy smell, often stronger after sex or a period (BV)
- Thick, white, clumpy discharge (yeast)
- Itching, burning, or redness of the vulva (yeast)
- Pain or burning with sex
- Burning when urine touches irritated skin
- Symptoms that return soon after treatment
Labs to ask about
- A vaginal swab checked for pH and under a microscope, or a lab test for BV
- Yeast culture for recurrent infections, to identify the species and guide treatment
- Testing for trichomoniasis, chlamydia, and gonorrhea
- A1c or glucose with repeat yeast infections
- A vulvar exam, and sometimes a biopsy, if itching persists without infection
Treatments your doctor may discuss
- Metronidazole or clindamycin for BV, sometimes followed by a longer course of twice-weekly suppressive treatment
- Treating male partners at the same time, which lowered BV recurrence in a 2025 trial
- Fluconazole weekly for 6 months for recurrent yeast infections, or oteseconazole for women who can't become pregnant
- Boric acid vaginal capsules, with clinician guidance, for resistant yeast or BV. It's toxic if swallowed and not safe in pregnancy.
- Vaginal estrogen after menopause, when low estrogen is part of the problem
Supportive steps to discuss with your provider
- Don't douche or use scented washes, wipes, or sprays. Douching is a known risk factor for BV.
- Get tested before treating a repeat infection at home. Many women who self-treat for yeast have something else.
- Use condoms, which lower BV recurrence.
- Know that evidence for probiotics, by mouth or vaginally, is limited and mixed. Ask before relying on them.
- Keep boric acid stored away from children and pets.
See a doctor promptly if you have
- Fever, pelvic pain, or pain with movement along with discharge: get same-day care (possible pelvic infection)
- Any vaginal symptoms during pregnancy
- Sores, blisters, or ulcers on the vulva
- Three or more yeast or BV infections in a year
- Itching or discharge that doesn't clear after treatment
