I have recently felt short of breath. After examination, increased respiratory resistance was found, indicating the presence of airway narrowing or obstruction. I would like to understand what this specifically means.

Increased respiratory impedance usually indicates elevated airway resistance, which may be caused by various factors including, but not limited to, asthma, chronic obstructive pulmonary disease (COPD), bronchitis, pulmonary infections, or allergic reactions. These conditions can lead to congestion and swelling of the airway mucosa, increased secretions, and consequently narrowed airways, making breathing difficult. Patients may experience symptoms such as wheezing, chest tightness, and shortness of breath; in severe cases, it can even be life-threatening.
In response to increased respiratory impedance, the first step is to undergo comprehensive pulmonary function tests to identify the specific cause. Doctors may prescribe inhaled corticosteroids or other bronchodilators to reduce airway inflammation and relax airway muscles, thereby decreasing respiratory impedance. During treatment, patients should ensure adequate rest, avoid strenuous exercise, drink plenty of water, and avoid consuming irritating foods such as chili peppers and Sichuan peppercorns. Additionally, maintaining healthy lifestyle habits, such as not smoking and limiting alcohol intake, can help prevent the onset and progression of related diseases.
