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)
  • • Protects against harmful bacteria
  • • Produces hydrogen peroxide

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.
