Why Does Respiratory Efficiency Decline During Pregnancy?

Dear expectant parents, pregnancy is a journey filled with wonders, but physical changes can sometimes bring discomfort, such as shallow breathing or shortness of breath. This is usually due to physiological adjustments to accommodate fetal growth and is a normal phenomenon. According to the WHO 2020 guidelines, understanding these changes can help you cope more calmly. Rest assured, in most cases, this is temporary and reflects the remarkable effort your body is making for your baby!

Possible Causes

• Hormonal Changes: Increased levels of pregnancy hormones (such as progesterone) may relax the respiratory muscles, leading to shallower breathing and reduced oxygen exchange efficiency.
• Uterine Expansion and Pressure: As the fetus develops, the uterus pushes upward against the diaphragm, reducing the space for lung expansion and decreasing lung capacity.
• Increased Metabolic Demand: A pregnant woman's metabolism speeds up, increasing oxygen demand by approximately 20%, but the respiratory system's capacity may temporarily struggle to meet this demand.

Home Care Recommendations

• Maintain Good Posture: Sit with your back straight and use pillows to elevate your upper body while sleeping to help your lungs expand.
• Practice Deep Breathing: Perform slow diaphragmatic breathing exercises daily (inhale for 5 seconds, exhale for 5 seconds) for 5-10 minutes each time to improve oxygen intake.
• Avoid Environmental Irritants: Stay away from smoke, dust, or crowded places; ensure indoor air circulation; engage in moderate exercise like walking, but avoid overexertion.

Conclusion

Understanding respiratory changes during pregnancy can help you welcome your new life with greater peace of mind. Remember, these adjustments reflect your body's wisdom in safeguarding your baby's growth. The AAP 2022 guidelines emphasize that most pregnant women can alleviate discomfort through simple care. You are not alone—seek support from family and enjoy this unique journey! Future parents, well done, you're doing great!
