Maternal health: Poorly controlled asthma during pregnancy can impact the mother's health.It may result in reduced respiratory function and overall well-being.Chronic inflammation and uncontrolled asthma symptoms can lead to persistent airway damage.Severe exacerbations and hospitalizations during pregnancy can also have long-term emotional and psychological effects on the mother, potentially leading to anxiety, depression, and reduced quality of life.Effective asthma management is crucial to preserving the mother's health and mental well-being [5].
Childhood asthma risk: Children born to mothers with asthma are at an increased risk of developing asthma and allergic diseases.The intergenerational impact of maternal asthma highlights the importance of understanding and managing asthma during pregnancy.While genetics plays a role, environmental factors and exposures during pregnancy can influence a child's susceptibility to asthma.Therefore, optimizing asthma control in pregnant women may reduce their offspring's risk of childhood asthma and related health issues [61].
Healthcare utilization: Poorly controlled asthma during pregnancy can lead to increased healthcare utilization for both the mother and child in the years following birth.This includes regular medical appointments, prescription medications, and treatments related to asthma.Managing asthma effectively during pregnancy can help reduce the need for ongoing medical interventions and enhance the mother's and child's well-being [5].
Quality of life: The long-term quality of life for both the mother and child can be influenced by the experiences and management of asthma during pregnancy.Chronic uncontrolled asthma can lead to physical discomfort, emotional distress, and limitations in daily activities.On the other hand, optimizing asthma control can have positive implications for long-term well-being.By effectively managing asthma during pregnancy, the mother can improve her quality of life and provide a healthier start for her child [40].

Conclusions
In conclusion, this comprehensive review of asthma in pregnancy has shed light on the intricate interplay of factors that influence maternal and fetal health during this crucial period.The prevalence of asthma in pregnant women, combined with the physiological changes induced by pregnancy, underscores the significance of understanding and effectively managing this condition.Proper diagnosis, medication management, personalized asthma action plans, lifestyle modifications, and stress reduction are integral to ensuring optimal asthma control.Healthcare providers are central to this process, offering education, monitoring, and individualized care.The importance of proper asthma management in pregnancy cannot be overstated, as it not only improves maternal and fetal outcomes but also has the potential to impact longterm health, both for the mother and her child.Ongoing research, precision medicine, and a holistic approach to care promise to enhance further outcomes in managing asthma during pregnancy.
