Yeast infections are commonly caused by a fungus known as Candida, which is naturally present in small numbers in the vagina. An imbalance between bacteria and yeast in the vagina can prompt an overgrowth of yeast, leading to symptoms. Certain medications, particularly broad-spectrum antibiotics, are likely to cause yeast infections as they can kill not only harmful bacteria but also the good bacteria that prevent yeast overgrowth.

Candida can also cause infections of the mouth, known as thrush or oral thrush, especially when transferred from the genital region or when the immune system is compromised. Conditions such as diabetes, hormonal changes, and even the use of certain hygiene products can increase the risk of yeast infections. Condom use can help prevent the transmission of yeast infections between partners if used correctly and consistently.

Men are also susceptible to yeast infections, which can cause an infection of the penis known as balanitis, characterized by pain, redness, and swelling. It is a common misconception that only women are affected by yeast infections; men, particularly those with foreskins, can develop these infections too.

Understanding the triggers and maintaining good hygiene are essential steps in preventing yeast infections. For those recurring cases or more information, visit Baylor College of Medicine or consult the resources at Harvard Health and Children’s Hospital for pediatric concerns.
