It’s common for females of childbearing age to experience yeast infections right before their periods. Due to the lack of education and awareness concerning yeast infections, many women inquire, “Why do I get a yeast infection before my period?” The following description is all bout yeast infections that occur before periods. 

Yeast infections, also known as Candidiasis, usually occur due to fluctuations in hormonal levels, particularly right before menstruation. The surge in estrogen levels causes Candida to proliferate rapidly under favorable conditions and cause infections. Limited scientific evidence reveals that three out of ten women experience rapid growth of yeast cells a week before their periods.

Menstrual cramping, mood fluctuations, bloating, and other premenstrual indicators accompanying menstruation are somewhat of a nuisance for several women. But if you also get a yeast infection, your periods may worsen. Vaginal yeast infections are mainly caused by yeast species called Candida albicans. Nevertheless, antifungal treatment-resistant yeast infections are caused by other uncommon fungal strains, such as Candida glabrata and Candida krusei.

Clinical Manifestation

Signs and symptoms of vaginal yeast infections occurring in women before menstruation:

  • Irritation and itching in the vagina and vulva
  • Redness and swelling of the vagina
  • Heavy feeling in the lower abdomen
  • Thick white vaginal discharge resembling cottage cheese-like texture
  • Vaginal secretions with or without odor
  • Dull pain every time
  • Sharp burning pain while urinating
  • Rash around vagina

Why Do I Get A Yeast Infection Before My Period?

Why do I get a yeast infection right before my period? It is the question that many women ask because some of them get the infection a week before menstruation, while a few experience such distress at the same time of their menstrual cycle. Such regular infections are also known as vulvovaginitis.

Various hormones are raised and decreased during menstruation in the body. Estrogen typically spikes during ovulation and gradually decreases before the menses start. Moreover, progesterone often reaches its maximum as your menstruation approaches. During menses, progesterone and estrogen levels are at their minimum levels. These hormonal fluctuations favor yeast proliferation. Some studies suggest that imbalances in estrogen are linked to the overgrowth of Candida albicans, causing vaginal yeast infections.

Other Causes

Though ninety percent of antifungal treatment-responding vaginal yeast infections are caused by Candida albicans, amongst the total of 200 Candida strains, other less causative species are:

  • Candida glabrata
  • Candida krusei
  • Candida tropicalis
  • Candida parapsilosis

Several medical conditions and general health status can increase the incidence of vaginal yeast infections before periods in women. For example, a patient with a weakened immune system due to HIV/AIDS, chronic diseases, or cancer, and people with poor diet and lifestyle are prone to yeast infections. Similarly, patients with diabetes mellitus may get recurrent yeast infections due to the surge in glucose levels in the blood and urine.

Pregnant females and those who are consuming oral contraceptives experience hormonal fluctuations and thus are at risk of developing vaginal yeast infections. Nevertheless, women who use contraceptive devices encounter yeast infections due to unhygienic practices and usage. Prolonged antibiotics also indirectly cause yeast infections. The reason is that antibiotics can kill good bacteria in the vagina that protects it against microbial proliferation, including yeast. Without enough good bacteria, Candida may find the chance to thrive.
