Yeast vaginitis, also known as candidal vaginitis, generally forms due to improper care. Normally, the vaginal environment is acidic. If a person is particularly hygienic and uses cleansing solutions or water to wash the vagina daily, it can disrupt the vaginal microbiota, leading to recurrent episodes of yeast vaginitis. Additionally, long-term use of large doses of anti-inflammatory drugs can also cause an imbalance in the vaginal microbiota, resulting in recurrent yeast infections. Furthermore, patients with poorly controlled diabetes may also experience recurrent yeast infections. Pregnant women, 30%-40% of whom, may also develop yeast vaginitis due to microbial imbalance. Moreover, in households where someone has athlete's foot, washing socks and shorts together can also lead to yeast infections. Therefore, in addition to treatment, the precautions mentioned earlier should also be taken seriously.
