Increased and blurred texture in both lungs is most often seen in acute bronchitis and acute episodes of chronic bronchitis, that is, diseases with coughing and coughing and other lower respiratory tract infections. Increased texture in both lungs is usually seen in patients who have been smoking for a long time, and repeated attacks lead to increased and thickened lung texture. If accompanied by an acute exacerbation, increased and blurred changes are likely to occur. Clinically, according to chest X-rays and chest CT examinations, the manifestations such as increased and blurred texture in both lungs can be suggested. If the patient is excluded from long-term exposure to dust, previous old tuberculosis, chronic bronchial dilatation and other diseases, the increased and blurred texture of both lungs is mainly considered acute and chronic bronchitis, which is usually treated with antibiotics and herbal medicine. The blurred texture can disappear, but the increased texture generally does not disappear easily, requiring the patient to quit smoking and enhance lung exercise.
