Constipation may increase the risk of developing wheezing or asthma later in life. This meta-analysis suggests a significant association between childhood constipation and later respiratory symptoms.
Area of Science:
- Pediatric Health
- Respiratory Medicine
- Gastroenterology
Background:
- Constipation is a common childhood issue.
- A potential link between constipation and respiratory conditions like wheezing and asthma has been proposed but remains debated.
- This study investigates the association between constipation and the risk of wheezing/asthma.
Purpose of the Study:
- To systematically evaluate the relationship between constipation and the risk of developing wheezing or asthma.
- To synthesize evidence from existing studies to clarify this association.
Main Methods:
- A comprehensive literature search was conducted across PubMed, Embase, and Web of Science databases.
- Data from eligible studies published between 1955 and January 2022 were independently extracted and quality assessed by two reviewers.
- Results were pooled using appropriate meta-analysis models (fixed-effects or random-effects).
Main Results:
- Three studies with a total of 178,661 participants were included in the meta-analysis.
- Constipation was found to be significantly associated with an increased risk of wheezing/asthma in later life (RR = 2.02, 95% CI = 1.24-3.29, P < 0.01).
Conclusions:
- The findings suggest a positive association between constipation and the subsequent development of wheezing/asthma.
- Further high-quality, prospective studies are needed to confirm this association and explore potential confounding factors.

Asthma-II: Pathophysiology and Classification
Additionally, environmental and genetic factors play crucial roles in determining an individual's susceptibility to asthma and the severity of their condition.
Critical processes in asthma pathophysiology include:

Classification of Asthma
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.

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...
