Can the birth control pill cause yeast infections?

The birth control pill can increase the risk of developing a yeast infection. This is because the pill contains hormones that can lead to an increase in the presence of yeast in the vagina. Additionally, the pill can also cause a decrease in the number of good bacteria that help to keep the yeast in check. In addition to the pill itself, other forms of hormonal contraception, such as the vaginal ring, contraceptive patch and injectable contraceptives can also increase the risk of yeast infections.
