Vaginal infections in pregnancy: the symptoms

During pregnancy, many women experience an increase in vaginal discharge. It is the so-called hydrorrhea and it is absolutely normal. But there are losses that can be caused by infections which, conversely, must be treated immediately.

Pregnancy bleeding is normal due to hormonal changes. If these discharges are white watery and odorless ,  they are usually normal discharges.

However, if you experience some symptoms (pain, itching) and suspect an infection, or the losses have a different appearance and give off an unpleasant smell, you need to notify your gynecologist because a vaginal infection could be in progress.

How to recognize a vaginal infection?

The main symptoms are: itching, burning, vaginal discharge and pain during sexual intercourse.

The losses have a color that can be grayish, but also whitish or yellowish with a different consistency from normal ones.

If you suspect an infection, it is essential to inform your gynecologist who will carry out a vaginal swab in order to diagnose the type of pathology.

Infections can increase the risk of miscarriage or stillbirth.

It has been shown that by treating bacterial infections early with antibiotics, it is possible to prevent miscarriage or complications during pregnancy. For this reason it would be advisable to carry out some checks before tackling a pregnancy in order to eliminate any dangerous bacteria. Even asymptomatic bacterial infections can in fact pose a threat to the health of the fetus.

What are the most common vaginal infections in pregnancy?

Mycosis (Candida)

They are recognized because they cause itching in the vagina and in the surrounding area and inflammation, pain is felt both during urination and during sexual intercourse.
