Can normal people have pleural thickening?

Normally, people do not have thickened pleura. The specific analysis is as follows:

The pleura is a thin, smooth membrane that lines the inner surface of the chest wall and the surface of the lungs. The layer covering the lung surface is called the visceral pleura, while the layer lining the chest wall is known as the parietal pleura. The space between these two layers is called the pleural cavity, which normally maintains lung expansion through negative pressure. In healthy individuals, pleural thickening does not typically occur. However, if inflammatory conditions affect the lung or pleural tissues, or if diseases such as diffuse malignant mesothelioma or pneumothorax are present, pleural thickening may develop. This can also lead to symptoms such as coughing and difficulty breathing.

It is recommended to maintain good daily habits and avoid excessive fatigue to prevent physical discomfort. If any symptoms occur, prompt medical attention is advised.
