Vaginal infections during pregnancy

Vaginal infections during pregnancy
Due to the increased hormonal activity that occurs during pregnancy, expectant mothers are more susceptible to a number of test troxin vaginal infections. Below we will see what are the most common causes and how they should be treated during pregnancy.

What causes vaginal discharge in pregnancy?

Your body transforms into many aspects when you are pregnant and increasing vaginal discharge is just one of the not so fun changes. If the vaginal discharge remains clear or white, odorless, it is considered normal and is a sign that the vagina is healthy. But sometimes the excess discharge indicates an infection, which is probably caused by an alteration in the natural balance of the bacteria living in the vagina. The four vaginal infections that can usually affect pregnant women are: bacterial vaginosis (BV), fungal infections, group B streptococcus (GBS) and trichomoniasis. The good news is that when vaginal infections are diagnosed on time they are easy to treat and cure. The difficult part is to differentiate between normal vaginal discharge and discharge indicating an actual infection. Here we outline the causes of each infection, symptoms, treatments and some prevention tips.

Vaginal discharge during pregnancy: When to worry?

Bacterial vaginosis (BV)

Approximately 1 in 5 pregnant women will develop this condition, according to the National Institutes of Health. Bacterial vaginosis occurs when there is an overgrowth of naturally occurring bacteria in the vagina, which, in pregnancy, can be influenced by hormonal changes. If left untreated, symptoms persist and the baby may be born prematurely or have a low birth weight. (In women who are not pregnant, BV can lead to pelvic inflammatory disease, which can cause infertility or damage to the fallopian tubes.) Bacterial vaginosis can be diagnosed with a single vaginal culture.

Sometimes this condition goes away on its own. If the woman is in her first trimester of pregnancy, the doctor can wait until her second trimester to treat her. A course of antibiotics, usually metronidazole or clindamycin, is almost always the solution.


Do not wear underwear or sweaty swimwear. It is recommended to wear clean cotton underwear after you have finished swimming or exercising.

Wear comfortable or cotton clothing that allows air circulation. Avoid pantyhose or tight pants, because they can cause sweat that is conducive to bacteria.

Sleep without underwear, as this can reduce the risk of infections.

Clean from front to back when going to the bathroom. This will prevent bacteria from spreading from the anus to the vagina.

Avoid bath oils, because they can trap bacteria.

Yeast Infection


yeast infection is usually caused by overgrowth of Candida albicans, a fungus that lives naturally in the vagina. During pregnancy, increasing levels of estrogen and progesterone helps create the ideal environment for yeast to thrive. Other causes of fungal infections include the consumption of antibiotics and sexual intercourse, as they can alter the natural pH of the vagina. The doctor can diagnose a yeast infection with a very simple vaginal culture.
