Enhanced texture in both lungs is a result of a hospital imaging test and means that there is a change in the lung tissue. There are many reasons for double lung texture enhancement, which can be caused by lifestyle factors such as long-term smoking, or it can be a symptom of a certain disease, such as chronic bronchitis and chronic obstructive pulmonary disease (COPD). 1. Long-term smoking: long-term smoking and with the gradual increase in age, the lungs are more damaged, which can lead to lung texture enhancement and thickening, which is a physiological phenomenon. 2. Chronic bronchitis: it is a chronic inflammatory disease, which can be caused by infection, impaired immune function and other factors, the main symptoms can be manifested as coughing, coughing up sputum, wheezing, etc. The X-ray film can find that the lung texture is thickened, disorganized, and show a striated, reticulated, or speckled shadow. 3. Chronic Obstructive Pulmonary Disease (COPD): Chronic obstructive pulmonary disease (COPD) is a kind of chronic airway disease, which can be caused by heredity, smoking and other factors. The main symptoms can be shortness of breath or dyspnea during activities, which can be relieved after rest, etc. X-ray examination can see increased and disorganized lung texture and growth of anterior and posterior thoracic diameter. There are other causes of double lung texture enhancement, you should immediately go to the hospital for further relevant examinations to clarify the cause of the disease and actively cooperate with the doctor’s treatment.
