Short of breath after walking for a short period of time

Shortness of breath after walking for only a short period may be caused by physiological factors or pathological conditions such as asthma, emphysema, etc. The specific analysis is as follows:

I. Physiological Factors

If an individual lacks regular physical exercise in daily life, lung capacity may decrease, leading to shortness of breath after brief walking. This can be alleviated through appropriate participation in physical exercise.

II. Pathological Factors

1. Asthma

Asthma may be triggered by genetic and environmental factors. During an attack, the airways undergo abnormal constriction, preventing normal airflow and causing symptoms such as shortness of breath. It is important to follow medical advice and use medications promptly, such as salmeterol fluticasone powder inhaler or salbutamol inhalation aerosol.

2. Emphysema

Emphysema may result from bronchial obstruction or imbalance in elastase levels. Air becomes trapped in the alveoli, gradually increasing intra-alveolar pressure and impairing normal oxygen supply, thus causing this symptom. Treatment options include bronchoscopic lung volume reduction surgery performed at a qualified medical facility.

In addition, shortness of breath after minimal walking may also be caused by conditions such as coronary atherosclerotic heart disease, pneumonia, or lung cancer. It is recommended to maintain a light diet during treatment.
