Analyzing spirometry profile of pulmonary function pattern among gestating women with bronchial asthma: A case–control study

Asthma is a widespread respiratory illness that affects millions of people worldwide, including pregnant women. Using spirometry testing, this study examines the effects of pregnancy on the lungs of pregnant women with and without bronchial asthma. The survey included 200 asthmatic pregnant women overall and 100 pregnant healthy women. FEV1, PEFR, FVC, and FEV1/FVC ratio, among other lung function indicators, were measured during the second and third trimesters of pregnancy. The findings show that pregnant women with asthma have significantly worse lung function than healthy pregnant women, with lower FEV1, PEFR, and FEV1% values. In addition, changes in lung function and body mass index (BMI) were observed between the second and third trimesters. The FEV1/FVC ratio remained largely stable, although both FVC and FEV1% decreased significantly. These results highlight the dynamic nature of lung function and BMI during pregnancy and also highlight the importance of monitoring these changes for the health of expectant mothers and their unborn children. To ensure maternal and fetal health, it is essential to understand these physiological changes, especially in people with asthma. Future evaluation of spirometry data should consider reference equations tailored to pregnant women. This will provide important insights into the complex relationship between respiratory health and pregnancy.
