What is the main symptom of bacterial vaginosis?

The main symptom of bacterial vaginosis is a fishy odor, which is often described as having a noticeable, unpleasant smell, particularly after sexual intercourse or during menstruation. This odor arises due to an imbalance in the normal flora of the vagina, leading to an overgrowth of certain bacteria. Bacterial vaginosis is characterized by this unique odor, which distinguishes it from other vaginal infections, such as yeast infections or sexually transmitted infections.

In contrast, while itching, thick discharge, and burning sensations can occur in other vaginal conditions, they are not the hallmark signs of bacterial vaginosis. For instance, yeast infections often present with intense itching and thick, clumpy discharge resembling cottage cheese, accompanied by irritation or burning. This contrast in symptoms helps healthcare providers identify bacterial vaginosis effectively, especially in patients presenting with vaginal symptoms.
