Clinical Observations in Nepal
At our clinic in Kathmandu, Bacterial Vaginosis is the #1 most common vaginal infection we treat. Many patients present with recurrent symptoms because they didn't receive proper partner treatment or follow-up care.
- Recurrence Rates: 50-70% of women experience recurrence within 12 months without proper management and partner education.
- Misdiagnosis: Often confused with yeast infections or trichomoniasis, leading to ineffective treatment and prolonged symptoms.
- Partner Treatment: While BV isn't sexually transmitted, treating partners can reduce recurrence rates significantly.
Understanding Bacterial Vaginosis
Bacterial Vaginosis (BV) is the most common vaginal infection in women of reproductive age, affecting approximately 15-30% of women at any given time. It occurs when there's an imbalance in the natural bacteria that live in the vagina.
[नेपाली] ब्याक्टेरियल भेजिनोसिस (बीभी) प्रजनन उमेरका महिलाहरूमा सबैभन्दा सामान्य योनि संक्रमण हो, जुन कुनै समयमा १५-३०% महिलालाई असर गर्छ। यो तब हुन्छ जब योनिमा बस्ने प्राकृतिक ब्याक्टेरियामा असन्तुलन हुन्छ।
Normal Vaginal Flora
- • Dominated by lactobacilli bacteria
- • Maintains acidic pH (3.8-4.5)

BV Bacterial Imbalance
- • Reduced lactobacilli count
- • Increased pH (>4.5)
- • Overgrowth of anaerobic bacteria
- • Gardnerella vaginalis dominance
BV Symptoms & Warning Signs
The most characteristic symptom of BV is a fishy vaginal odor, which may be more noticeable after sexual intercourse or during menstruation. However, up to 50% of women with BV have no symptoms at all.

What causes bacterial vaginosis?
BV is caused by imbalance in vaginal bacteria - overgrowth of Gardnerella vaginalis and other anaerobes, decrease in protective Lactobacillus. Risk factors: douching, multiple sexual partners, new partner, antibiotics, hormonal changes, IUD use, smoking. Not sexually transmitted but sexual activity increases risk.
What are symptoms of bacterial vaginosis?
50% of women have NO symptoms. Common symptoms: thin, grayish-white vaginal discharge, strong fishy odor (especially after sex), vaginal itching, burning during urination. Symptoms worsen during menstruation. Unlike yeast infection, BV discharge is not thick or white.

Why does BV keep coming back?
BV recurrence is common due to: incomplete treatment (take full antibiotic course), reinfection from partners, persistent vaginal dysbiosis, douching/harsh soaps, hormonal changes, stress, unprotected sex. Prevention: avoid douching, use condoms, take probiotics, maintain vaginal pH balance.
How is BV different from yeast infection?
BV: thin grayish discharge, fishy odor, pH >4.5, caused by bacteria overgrowth, treated with metronidazole. Yeast infection: thick white cottage-cheese discharge, no odor, pH 4-4.5, caused by Candida fungus, treated with antifungals. Both cause itching but different discharge and treatment.
Can BV cause pregnancy complications?
