Antibiotics are known for their role in eliminating harmful bacteria from the body, but they can also inadvertently target beneficial bacteria. This imbalance often leads to yeast infections in women, characterized by itching, burning, and irritation in the vaginal area. Dr. Sophia Haroon Dar, an internal medicine specialist, explains this phenomenon, highlighting that antibiotics don’t distinguish between “good” and “bad” bacteria.

Yeast infections cause intense itching and a cheesy, dry discharge. Although yeast organisms are a natural part of the vaginal flora, their overgrowth can lead to infection. Treatments like Metronidazole gel (0.75%) are used intravaginally to manage these symptoms. Globally, about 138 million women experience vulvovaginal candidiasis annually. Disruption in the vaginal environment, such as that caused by antibiotics, can lead to Candida organisms transitioning from harmless to pathogenic.

Bacterial Vaginosis (BV) is another condition that can be confused with yeast infections. It presents with a thin, grayish-white discharge and an unpleasant odor. Metronidazole, either in oral form or as a vaginal gel, is a common treatment for BV. However, long-term use of these medications can lead to secondary yeast infections.

Self-diagnosis and treatment of yeast infections are possible if one is familiar with the symptoms. However, consulting a healthcare provider for a formal diagnosis is always recommended, especially in cases of uncertainty.
