Why the Cardiovascular System Burden Increases in Pregnant Women
Dear expectant parents, pregnancy is a journey filled with joy and changes. The increased burden on the cardiovascular system is a common physiological phenomenon. According to post-2020 guidelines from the World Health Organization (WHO) and the American Academy of Pediatrics (AAP), this is the body's natural adjustment to support fetal growth. Understanding these changes can help you better care for the pregnant woman's health and avoid unnecessary concerns.
Possible Causes
- Significant increase in blood volume: During pregnancy, blood volume typically increases by 40-50% to meet the fetus's oxygen and nutritional needs.
- Increased cardiac workload: The heart needs to pump more blood, leading to an increase in heart rate and cardiac output.
- Hormones affect vascular function: Hormones like progesterone cause blood vessels to dilate, which may lead to blood pressure fluctuations.
Home Care Recommendations
- Moderate exercise: Engage in light activities like walking for 20-30 minutes daily to promote blood circulation.
- Ensure adequate rest: Avoid prolonged standing or overexertion and ensure 7-8 hours of sleep per day.
- Balanced diet: Choose low-sodium, high-fiber foods to maintain a healthy weight.
When to Seek Medical Attention
- ⚠️ If experiencing difficulty breathing or shortness of breath, seek immediate medical attention.
- ⚠️ If experiencing chest pain or palpitations, seek immediate medical attention.
- ⚠️ If experiencing severe edema (especially in the face or hands), seek immediate medical attention.
Conclusion
These changes are a natural adaptive process during pregnancy, reflecting the remarkable vitality of the maternal body. As new parents, maintaining positive communication and regular prenatal check-ups is key. Your care and support form the most beautiful starting point for welcoming new life.
