STIs in Pregnancy: What Every Woman Should Know

STIs during pregnancy can affect both mother and baby if not managed early. This guide explains common infections, symptoms, risks, screening, and safe treatment options. With timely care, regular checkups, and proper precautions, most women can protect their health and have safe, healthy pregnancy outcomes.

Pregatips
Pregnancy care primarily focuses on health, safety, and making excellent choices for both mother and baby. Most mothers take good care of their diet, sleep, and regular visits to the doctor, but sometimes infections, like sexually transmitted infections, are often ignored. Nevertheless, they deserve more attention.
The good news is that most sexually transmitted diseases can be diagnosed early and treated safely. With the right information and quick and proper treatment, you can stay away from any complications during pregnancy.

We spoke to Dr Khushboo Saxena, Senior Consultant, Obs & Gynae, ShardaCare-HealthCity, to understand this better and get you verified information.


Common STIs Seen in Pregnancy

Sexually transmitted infections (STIs) are infections transmitted through sexual activity. Being aware of the common types helps you be more cautious.

Chlamydia

It is a bacterial infection that is asymptomatic, yet it affects the uterus and the urinary tract and increases the chances of preterm births. After birth, it can cause eye or lung infections in the baby.

Gonorrhoea

Gonorrhoea is a bacterial infection that infects the reproductive system, throat, or anus. If untreated, it may create dangers during pregnancy and cause serious eye infections after birth.

Syphilis

Syphilis is a bacterial infection that develops in stages and goes unnoticed for some time. It can be transferred to the fetus during pregnancy and cause miscarriage, stillbirth, or other serious issues.

Genital Herpes

Genital herpes is a viral disease due to the herpes simplex virus, leading to painful sores or blisters, or serious newborn complications like blindness, deafness, seizures, meningitis, damage to organs like lungs, liver, or heart, or sometimes permanent disability, or even death. Transmission may occur during delivery if active sores are present.

HIV

HIV is a viral disease compromising the body's immune response. This can be transmitted to the baby during pregnancy, birth, or breastfeeding.

Hepatitis B

Hepatitis B is a viral disease affecting the liver and spread via contaminated body fluids. This would occur during birth, but prompt vaccination gives protection to the baby.

HPV

HPV (human papillomavirus) is a viral disease during pregnancy that usually does not harm the baby, but it can be linked to complications like premature rupture of membranes, miscarriage, and low birth weight.

Trichomonas

This is an infection caused by a tiny parasite called trichomonas vaginalis. It spreads through sexual contact and raises the risk of premature birth, premature rupture of membranes, and low birth weight.

Untreated STIs can be risky for both mother and baby, leading to complications like miscarriage, early rupture of membranes, preterm birth, low birth weight, stillbirth, and infections after delivery.”

Screening and Diagnosis During Pregnancy

Dr Khushboo Saxena recommends pregnant women undergo STI testing at their first prenatal appointments and also in the third trimester, especially before 36 weeks, if there are risk factors like a recent STI or a new or multiple sexual partners.

Among the key tests that can be conducted are:

  • Blood analysis for diseases like HIV, syphilis and hepatitis B
  • Urine tests or taking a sample from the vagina (swab test) to determine the presence of chlamydia or gonorrhoea
  • Follow-up testing aimed at confirming the effectiveness of the treatment as far as the above-stated diseases are concerned

Safe Treatment Options During Pregnancy

According to NCBI, treatment can involve using the following medications:

  • Antibiotics for treating infections such as chlamydia or gonorrhoea
  • Antiviral medications for treating herpes
  • Antiretroviral therapy for the treatment of HIV to prevent transmission to others
  • Preventive treatment for the infant after birth if necessary

How to Prevent STIs During Pregnancy

Dr Khusboo Saxena suggests the following preventive tips to lower your risk of STIs during pregnancy:

  • Getting tested for STIs early in the pregnancy
  • Making sure that your partner is tested and treated if necessary
  • Following your doctor’s recommendations and using protection
  • Keeping a relationship monogamous
  • Attending all prenatal checkups on time

When to Seek Immediate Medical Care

Some symptoms should be treated as emergencies while pregnant. Timely intervention can avert complications.

Get medical assistance immediately if you experience:

  • Severe abdominal pain
  • Fever accompanied by unusual vaginal discharge
  • Bleeding or spotting from the vagina
  • Painful rashes or sudden flares
  • Decreased fetal movement during late pregnancy
Having STIs during pregnancy could be alarming; however, they can be successfully treated when using appropriate remedies. The right treatment, timely testing, and close monitoring could help to minimise the risks for both mothers and their babies.

Maintain control over your health by becoming actively involved and learning more about STIs. You should not forget regular checkups and STI testing. By taking precautions, you will secure a successful delivery for yourself and your baby.
