Why can antibiotics cause yeast infections?

Antibiotics are medicines that kill bacteria causing infections. However, they can also kill good bacteria in the body. This can upset the balance of microorganisms in places like the mouth, intestines, and vagina.

When the good bacteria are reduced, yeast, which is a type of fungus, can grow too much. This is because the good bacteria usually help keep yeast growth in check. Without enough good bacteria, yeast can grow and cause an infection.

Key Points:

1. Antibiotics and Bacteria: Antibiotics are important for fighting infections, but they don't only target bad bacteria.
2. Balance Disruption: Killing good bacteria can lead to an imbalance, allowing yeast to grow.
3. Yeast Infections: When yeast grows too much, it can cause symptoms like itching and discomfort.

It's important to use antibiotics only when needed and as directed by a healthcare provider. This helps reduce the risk of yeast infections and other side effects.
