There is no dietary treatment for pneumoconiosis, and no food has a role in treating pneumoconiosis. However, pneumoconiosis can be treated with medication and oxygen therapy to improve symptoms and slow disease progression. Pneumoconiosis is a diffuse fibrotic change in lung tissue due to long-term inhalation of mineral dust during occupational activities. Pneumoconiosis usually has a long course, and even if the patient is removed from the dust-exposed environment, the disease will still progress and aggravate, mainly characterized by respiratory symptoms such as coughing, coughing up sputum, chest pain, and dyspnea. Food is not a cure for pneumoconiosis, but different foods can provide the body with the nutrients it needs to replenish energy. There is no specific and effective treatment for pneumoconiosis at present. You should get out of the dusty environment in time and focus on symptomatic treatment to slow down the development of the disease. For coughing and sputum, aminoglutethimide hydrochloride and N-acetylcysteine can be given under doctor’s guidance to resolve sputum; if there are symptoms such as wheezing, salbutamol aerosol, aminophylline and doxophylline can be given to calm the wheezing; hanpenghexine tablets can help to fight against the progression of fibrosis; when respiratory distress, oxygen can be given; lung transplantation can be considered for the end stage of the disease. Pneumoconiosis patients should pay attention to the prevention of respiratory infections. In terms of diet, they should have a light and easy-to-digest diet, ensure balanced nutrition, and eat more fresh vegetables. Appropriate physical exercise is also needed to improve lung function.
