Respiratory dysfunction in patients with irritable bowel syndrome.

Area of Science:

• Gastroenterology
• Pulmonology
• Internal Medicine

Background:

• Irritable Bowel Syndrome (IBS) is a common gastrointestinal disorder.
• Emerging evidence suggests potential links between IBS and extra-intestinal manifestations, including respiratory issues.

Purpose of the Study:

• To investigate respiratory symptoms and pulmonary function markers in patients diagnosed with Irritable Bowel Syndrome (IBS).

Main Methods:

• The study involved 40 IBS patients and 30 healthy controls.
• Pulmonary function was assessed using spirometry, measuring parameters like Forced Vital Capacity (FVC) and Forced Expiratory Volume (FEV).
• IBS subtypes were classified according to the Rome III criteria.

Main Results:

• Patients with IBS reported higher incidences of respiratory symptoms, including sputum (67.5%), cough (50%), dyspnea (37.5%), and wheeze (30%).
• A significant reduction in respiratory function markers was observed in IBS patients compared to controls, with decreased FVC, FEV, and FEV/FVC ratios.
• Specifically, FVC was 2.59±0.12 L in IBS patients versus 2.82±0.06 L in controls, and FEV was 2.18±0.12 L versus 2.42±0.73 L.

Conclusions:

• Irritable Bowel Syndrome patients demonstrate significantly impaired respiratory function.
• Constipation, a common feature of IBS, appears to be a potential underlying mechanism contributing to the decline in pulmonary function and the onset of respiratory symptoms.
