Aim:
To evaluate the association between caesarean section and risk of developing asthma.
Method:
We evaluated this association in a Danish cohort, comprising of 11,147 mothers and their babies of which 7119 mother-child pairs were included in the analyses. The mothers' reported asthma data on their children were linked to hospitalization records on mode of delivery.
Results:
The adjusted odds ratio for developing asthma was 1.11 (95% CI, 0.88-1.39) for caesarean sections versus vaginal births.
Conclusion:
We found no evidence that children being delivered by caesarean section have an increased risk of asthma.

Upper Respiratory Drugs: Antitussives, Expectorants, and Mucolytics
Antitussives include codeine, dextromethorphan (Robitussin), and benzonatate (Tessalon). Codeine and dextromethorphan exert their effects centrally by suppressing the cough reflex center in the medulla. Benzonatate operates peripherally within the respiratory tract by anesthetizing...
Asthma: Pathogenesis and Management
Asthma is classified as allergic and non-allergic. Allergens such as dust mites, pollen, and pet dander trigger allergic asthma, while factors like cold air, intense emotions, or exercise can induce non-allergic asthma.

Additionally, environmental and genetic factors play crucial roles in determining an individual's susceptibility to asthma and the severity of their condition.
