What is a common sign of bacterial vaginosis?

Bacterial vaginosis is characterized by a malodorous vaginal discharge, often described as having a "fishy" odor, especially after sexual intercourse or during menses. This condition arises from an imbalance in the normal bacterial flora of the vagina, leading to an increased presence of certain bacteria. The odor is a key symptom that distinguishes bacterial vaginosis from other vaginal infections.

While other symptoms can be associated with various conditions affecting vaginal health, they are not typically the hallmark presentations of bacterial vaginosis. For instance, thick, white discharge is more commonly associated with a yeast infection. Vaginal dryness and irritation may relate to hormonal changes or other types of vaginitis, but are not signatures of bacterial vaginosis. Similarly, painful intercourse can occur in various conditions but is not a specific indicator of bacterial vaginosis. The malodorous discharge, however, is a definitive and common sign that helps in diagnosing this condition.
