Breathing for Two

Today, we're exploring how pregnancy affects breathing. Growing a baby creates unique challenges for the respiratory system.

How Pregnancy Changes Breathing

Physical changes:

  • Diaphragm rises as uterus expands

  • Rib cage widens

  • Breathing becomes more diaphragmatic

  • Breathe 40% more air per minute by late pregnancy

Normal symptoms:

  • Mild shortness of breath (especially third trimester)

  • Feeling "out of breath" with light activity

  • Difficulty taking deep breaths

  • New or worsened snoring

Did You Know? Pregnant women breathe about 40% more air per minute by late pregnancy, even though lung capacity doesn't significantly increase.

When to Worry - Seek Medical Care

  • Sudden severe shortness of breath

  • Chest pain with breathing

  • Rapid heart rate with breathing difficulty

  • Blue lips or fingernails

  • Persistent cough or wheezing

"Some breathlessness is expected in pregnancy, but sudden or severe symptoms always need evaluation." - Maternal-Fetal Medicine Specialist

Common Issues

Pregnancy Rhinitis

  • Nasal congestion in up to 30% of women

  • Management: Saline rinses, humidifier, sleep elevated

Asthma During Pregnancy

  • Affects 8-13% of pregnant women

  • Well-controlled asthma is safe for baby

  • Continue medications as prescribed - uncontrolled asthma is more dangerous

Respiratory Infections

  • More susceptible during pregnancy

  • Get recommended vaccines (flu, COVID-19, pertussis)

  • Seek care for fever with respiratory symptoms

Safe Practices

Breathing Exercises

  • Diaphragmatic breathing: Hand on belly, breathe slowly through nose

  • Practice 5-10 minutes daily

  • Learn labor breathing patterns

Environmental Safety

  • Avoid secondhand smoke

  • Minimize chemical/fume exposure

  • Use air purifiers if needed

  • Request workplace accommodations if necessary

Medications

  • Generally safe: Most asthma medications, saline sprays

  • Avoid: Decongestants, unstudied herbal remedies

  • Key rule: Always consult providers before stopping prescribed medications

"Uncontrolled respiratory conditions pose greater risks than most respiratory medications during pregnancy." - Pulmonologist

Quick Tips

  • Practice breathing exercises daily

  • Monitor air quality at home and work

  • Continue prescribed respiratory medications unless told otherwise

  • Seek care promptly for concerning symptoms

Wrap-Up Challenge

This week:

  1. Practice diaphragmatic breathing daily

  2. Assess your air quality environment
