Pregnancy brings many changes to the body. One big change is how the immune system works. The immune system helps protect you and your growing baby. Most infections during pregnancy are mild and can be treated, but some can cause problems if they aren’t found early.
Why Infections Matter During Pregnancy
When you’re pregnant, your body fights germs differently. This can make it easier to get sick or have stronger symptoms. Some infections can affect the placenta, make labor start too early, or cause problems for the baby. That’s why doctors check for certain infections during prenatal visits.
Common Infections to Know About
Some infections that can cause problems during pregnancy include:
- Urinary tract infections (UTIs): These can lead to early labor if not treated.
- Group B Streptococcus (GBS): Most people are checked for this near the end of pregnancy.
- Flu and COVID‑19: These can be more serious during pregnancy.
- Listeriosis: A food infection usually caused by eating unpasteurized or unsafe foods.
- Sexually transmitted infections (STIs): These can affect both the mom and the baby.
Getting treatment early helps keep you and your baby safe.
Warning Signs to Watch For
Call your doctor if you have:
- Fever or chills
- Pain or burning when you pee
- Stomach pain that doesn’t go away
- Unusual vaginal discharge
- Flu‑like symptoms that get worse or don’t improve
Even small symptoms can be important, so don’t hesitate to ask your doctor.
How to Protect Yourself and Your Baby
Here are some simple ways to lower your risk of infection:
- Go to all your prenatal checkups
- Wash your hands often
- Follow food safety rules
- Stay updated on recommended vaccines
- Take any prescribed medicine exactly as your doctor says
Infections during pregnancy are common, and many are easy to treat when caught early. Staying aware, knowing the signs, and talking openly with your doctor can help protect your health and your baby’s health.
