Increased coarsening of the texture of both lungs is an imaging term for the imaging manifestations of a chest radiograph of the lungs. Increased coarsening of bilateral pulmonary texture refers to the increased coarsening of the channels composed of bronchi, pulmonary arteries, and pulmonary veins shown on chest radiographic images, and is an imaging sign that is often seen in reports of pulmonary chest radiographs. Increased thickening of the texture of both lungs is often indicative of a lung infection, usually due to respiratory disease. It can also be caused by long-term smoking. Clinical manifestations include cough, sputum, chest tightness, wheezing, and even stridor. Clinically, if the patient only has a slight increase in the thickening of the texture of both lungs, and there are no other obvious clinical symptoms, it can be left untreated for a period of time. But pay attention to rest, quit smoking, can eat more vegetables and fruits rich in vitamin C; strengthen physical exercise, enhance the body’s immunity. If the above symptoms occur, it is recommended to go to the hospital in time for early formal treatment.
