What Causes Yeast Infections?
2. Hormonal Imbalance
Yeast infections can also occur when the body’s natural balance of progesterone and estrogen is disrupted. Candida tends to overgrow when estrogen levels are high. Since yeast cells cannot increase in the pH level present during menstruation, often menstrual blood will clear up yeast infections with no further treatment.
Although contraceptives don’t directly cause yeast infections, your chance of developing one does go up when you are using a hormone-based method, such as birth control pills. They often contain progestin, a synthetic version of progesterone. This hormonal disruption can lead to yeast overgrowth.
