Pneumoconiosis can potentially lead to coughing at night. It is caused by the inhalation of dust, resulting in changes to the lungs. Patients often exhibit symptoms such as coughing, expectoration, chest tightness, and shortness of breath, and these symptoms progressively worsen. In severe cases, complications may include pulmonary heart disease or pulmonary cerebral disease. However, coughing at night is not necessarily indicative of pneumoconiosis. Other conditions, such as chronic obstructive pulmonary disease, bronchiectasis, pulmonary tuberculosis, and lung tumors, may also result in nighttime coughing. Thus, it is important to visit a hospital for comprehensive diagnostics including chest CT, complete blood count, and sputum tests for tuberculosis to establish a clear diagnosis. Pneumoconiosis is an occupational disease, and visiting a local institute for occupational diseases can aid in diagnosis.
