Causes of Vaginal Thrush: Candida albicans and Risk Factors
Vaginal thrush, also known as vulvovaginal candidiasis, is most commonly caused by the overgrowth of the fungus Candida albicans, although other Candida species like C. glabrata, C. parapsilosis, and C. krusei can also be responsible Odds1982Truss2007Mishra2017+1 MORE. Normally, Candida lives harmlessly on the skin and mucous membranes, but certain conditions can trigger its excessive growth, leading to infection Odds1982Truss2007Mishra2017.
Key risk factors for developing vaginal thrush include high estrogen levels (such as during pregnancy or while taking oral contraceptives), diabetes (especially gestational diabetes), a weakened immune system, and the use of antibiotics or corticosteroids Hingankar2021Mishra2017Hingankar2021. Wearing synthetic or tight clothing, which creates a warm and moist environment, can also encourage fungal growth, while cotton underwear and loose clothing are recommended for prevention Hingankar2021Hingankar2021. Postmenopausal women may be more susceptible due to reduced vaginal lubrication .
Common Symptoms of Vaginal Thrush

Self-Management and Treatment

Completing the full course of treatment is important to fully eradicate the infection . If a partner shows symptoms, they should also be treated to prevent reinfection . For women with recurrent thrush, it is recommended to test for diabetes as an underlying cause .
Conclusion
Vaginal thrush is a common fungal infection primarily caused by Candida albicans. It is characterized by itching, discharge, and discomfort, and is influenced by factors such as hormonal changes, diabetes, and clothing choices. While it is usually not dangerous, it can greatly affect a woman's quality of life. Effective treatments are available, and preventive measures can help reduce the risk of recurrence.
