What Pregnant Mothers Can Do to Reduce the Risk of Congenital Heart Disease
Congenital heart disease (CHD) develops during early pregnancy, and most cases cannot be fully prevented because genetics and early fetal development play major roles. However, pregnant mothers can still take steps that support a healthy pregnancy and may reduce certain risks. These actions focus on overall wellness, early prenatal care, and avoiding known environmental factors that may influence fetal heart development. Because every pregnancy is unique, mothers should always speak with a healthcare professional for personalized guidance.
Healthy Steps That Support Heart Development
Start prenatal care early
Early prenatal visits help healthcare teams monitor fetal development and identify concerns sooner. Regular checkups also support healthy pregnancy planning and allow mothers to receive timely guidance.
Take prenatal vitamins with folic acid
Folic acid supports early fetal development and reduces the risk of several congenital conditions. Many healthcare providers recommend folic acid before and during pregnancy as part of routine prenatal care.
Manage chronic health conditions
Conditions such as diabetes, high blood pressure, and thyroid disorders can influence fetal development. When mothers work with their healthcare team to manage these conditions, they support a healthier pregnancy environment.
Avoid harmful substances
Alcohol, to***co, and recreational drugs increase the risk of congenital conditions. Avoiding these substances supports fetal heart development and overall pregnancy health.
Review medications with a healthcare provider
Some prescription or over‑the‑counter medications may affect fetal development. Pregnant mothers should always consult a doctor before starting or stopping any medication.
Maintain healthy lifestyle habits
Eating balanced meals, staying active as recommended, and managing stress support overall maternal health. These habits help create a stable environment for fetal growth.
