During which weeks of pregnancy are symptoms of asthma most likely to worsen?

The correct answer indicates that symptoms of asthma are most likely to worsen during the weeks of 29 to 36 of pregnancy. This period aligns with several physiological changes that occur in a pregnant woman’s body.

As pregnancy progresses, particularly during the third trimester, there is an increase in respiratory demand due to the growing fetus, which pushes up against the diaphragm and reduces lung capacity. This mechanical restriction can exacerbate asthma symptoms, as the ability of the lungs to expand fully is compromised. Hormonal changes, particularly the increase in progesterone, can also lead to airway hyperresponsiveness, further complicating asthma management.

Asthma management during pregnancy is crucial, as uncontrolled asthma can pose risks to both the mother and the fetus. Understanding the timing of symptom exacerbation allows healthcare providers to closely monitor and adjust treatment plans for pregnant individuals, ensuring both maternal health and fetal well-being are prioritized.

Additionally, the timing of asthma symptom exacerbation is consistent with the known patterns of respiratory issues in pregnancy, thus supporting the choice that identifies 29 to 36 weeks as a period of notable concern.
