What is the main cause of vaginal yeast infections?

The main cause of vaginal yeast infections is the overgrowth of the Candida albicans fungus. This organism is a type of yeast that normally resides in the body without causing any issues. However, certain factors can disrupt the natural balance of flora in the vagina, leading to an overgrowth of this yeast. When conditions such as antibiotics usage, hormonal changes, or a weakened immune system occur, the population of Candida albicans can increase significantly, resulting in a yeast infection.

Understanding the role of Candida albicans is crucial because it highlights the importance of maintaining the microbial balance within the vaginal environment. This understanding can assist in the prevention of such infections and in recognizing the symptoms when they occur, allowing for prompt treatment.
