Vaginal yeast infections are a common concern, often linked to certain lifestyle choices and health conditions. The fungus Candida causes these infections, leading to symptoms like inflammation, intense itchiness, and a thick, white discharge from the vagina. Pain or burning sensations during urination or sex are also common.

One significant factor contributing to yeast infections is the use of hormonal contraceptives. Estrogen and other hormones found in oral contraceptives can alter vaginal cells, increasing susceptibility to infections. Additionally, “Risk for a yeast infection was doubled by use of oral contraceptives and tripled by spermicides,” according to Foxman.

Saliva can also cause irritation, facilitating Candida adherence and growth, particularly in the context of oral contraceptive and spermicide use within the last two weeks. A history of yeast infection diagnosis in the past year further raises the risk.

It’s important to evaluate your birth control method, as certain types like diaphragms and unlubricated or spermicide-treated condoms can facilitate bacterial growth. Other factors contributing to yeast infections include antibiotics use, menopause, pregnancy, and certain health conditions like diabetes.

Bacterial vaginosis (BV) is another condition linked to changes in vaginal bacterial balance, often associated with sexual activity. Though not an STI, BV involves an overgrowth of certain vaginal bacteria, leading to inflammation.

Yeast infections are prevalent, with about 75% of women experiencing them at some point. Symptoms include vaginal itching/burning, redness around the vagina, discomfort during intercourse, and increased discharge. Over-the-counter treatments are available for these infections.
