Yeast infection during pregnancy

Yeast infection (so called “vaginal candidiasis” or “vaginal thrush”) is vaginal infection triggered by fungus Candida albicans. Healthy vagina has balanced microbes and once the balance is disrupted, it provokes overgrowth of yeast infection (proliferation and grows out of control). Yeast infection during pregnancy is common condition, especially during the second trimester. It explained by dramatic hormonal changes (high estrogen levels), depressed immune system during pregnancy and gestational diabetes.

Yeast infection during pregnancy – causes

  • Hormonal changes trigger vaginal environment disturbances which cause overgrowth of Candida;
  • During pregnancy body produces more sugar which infiltrates into vagina, and sugar is the favorite food for fungus – more sugar, more fungus (intensive grow and spread);
  • Gestational diabetes is type of diabetes which starts during pregnancy and disappeared after delivery – it starts when pregnant body is not able to produce and use all the insulin it needs for pregnancy. Without enough insulin, glucose cannot leave the blood and be changed to energy – the concentration of blood glucose increases and stays high during whole pregnancy;
  • Sexual contacts could also trigger yeast infection during pregnancy (explained by additional vaginal trauma and possible sexually transmitted infections).
