This episode breaks down how the immune system works, how it shifts during pregnancy, and what those changes mean for staying healthy while you are expecting. You will learn why the most effective way to support your immune system begins with core foundations like sleep, nutrition, hydration, exercise, and stress management. The episode also examines the evidence on popular immune-support supplements and remedies, including vitamins and minerals, probiotics, choline, antioxidants, echinacea, elderberry, and medicinal mushrooms. Most importantly, we explore how to make sense of all the options so you can determine which supplements may be worth considering and when it makes sense to talk with your doctor or midwife about targeted support.

Many changes during pregnancy affect your cardiovascular system, which includes your heart and blood vessels. Some fluctuations in blood pressure are expected, but hypertensive disorders are still one of the leading causes of maternal and perinatal mortality worldwide.

Hypertensive disorders of pregnancy include chronic hypertension, gestational hypertension, preeclampsia, HELLP, and eclampsia. High blood pressure during pregnancy can place significant stress on your heart and kidneys and can contribute to heart disease, kidney disease, and stroke. It also increases the risk of preterm birth, placental abruption, and cesarean birth. When blood pressure is too high, it can reduce blood flow to the placenta and limit the oxygen and nutrients available to your baby. This is why your care provider monitors your blood pressure so closely throughout pregnancy.

Most pregnancy-related conditions resolve after birth, but the risk from hypertensive disorders does not end when your baby arrives. Mothers can develop dangerous symptoms in the days and weeks after birth, even if their blood pressure was normal throughout pregnancy. Recognizing warning signs and seeking medical attention right away can be life-saving.

Pregnancy can be a period of additional stress as you are experiencing many physical changes and symptoms, and are mentally preparing for birth and a new baby. In a sense, everything you expose yourself to during pregnancy can also affect your baby, and stress is not an exception. Physiological changes that occur when you are stressed can affect your developing baby, and high levels of stress may increase the risk of certain complications. The extent to which you and your baby are affected depends on your stress response and your ability to turn it off. The good news is that by understanding your stress response and learning evidence-based ways to manage it, you can reduce negative effects and support both your well-being and your baby's healthy development.

One of the first decisions you will make as a new parent is whether to vaccinate your newborn against hepatitis B. The first dose of this vaccine is recommended within 24 hours of birth, and most babies receive it before leaving the hospital. Hepatitis B is a serious viral infection that affects your liver. It can become chronic and, over time, lead to cirrhosis, liver failure, or cancer. Although the vaccine is effective, many parents have questions about safety, the timing of administration, and whether it is truly necessary for newborns. You have multiple options, including choosing to vaccinate, delay, or decline. This episode explores the evidence on the risks and benefits so you can make an informed decision and feel confident in your choices as a parent.

Your doctor or midwife monitors the fetal heart rate of your baby to assess their well-being and how well they are tolerating labor. They primarily use electronic fetal monitoring (EFM), which is the most common obstetric procedure during labor. EFM This allows your doctor or midwife to recognize signs of low oxygen and respond quickly if intervention is needed. While electronic fetal monitoring can identify emergencies, research shows that continuous monitoring does not necessarily improve outcomes and is linked to higher rates of cesarean and assisted births.

Most low-risk pregnancies can be safely monitored intermittently. Hospital policies, provider training, and individual risk factors all influence what type of monitoring is used. By learning about your options and discussing them ahead of time, you and your care provider can create a plan that keeps your baby safe while supporting the birth experience you want.
