Pneumoconiosis is an occupational disease, typically caused by long-term exposure to dust and polluted environments. In the early stages, patients may not exhibit any obvious clinical symptoms. Over time, as exposure to the dust continues, some patients may develop mild symptoms like coughing and even experience shortness of breath. Therefore, as patients continue to be exposed over a long period, their condition may progressively worsen, eventually leading to symptoms such as palpitations, chest tightness, difficulty breathing, coughing, and phlegm production. It is crucial to take these symptoms seriously in such populations. Should symptoms like coughing, phlegm production, chest tightness, or shortness of breath arise, medical attention must be sought promptly to avoid delaying treatment.
