Asthma in pregnancy - Management, maternal co-morbidities, and long-term health.

Asthma is the most prevalent chronic disease in pregnancy, and as symptoms can change with pregnancy, and exacerbations of asthma are common, regular review of asthma symptoms, the provision of self-management education, and appropriate medication use are the hallmarks of management. Co-morbidities are also prevalent among pregnant women with asthma, with obesity, gestational diabetes, hypertension, rhinitis, depression, and anxiety, more common among women with asthma than women without asthma. Less is known about reflux, obstructive sleep apnoea and vocal cord dysfunction, along with nutritional deficiencies to iron and vitamin D. Maternal asthma impacts the offspring's long-term health, particularly in increasing the risk of early life wheeze and asthma in childhood. While breastfeeding may modify the risk of infant wheeze, less is known about the mechanisms involved. More research is needed to further understand the relationship between asthma in pregnancy and the risk of poor neurodevelopmental outcomes, such as autism.
