Is the weight gain of both lungs serious?

The cause of thickening of lung markings is generally due to bronchitis or pneumonia in the lungs, mainly to see if there are other complications, if only some cough and fever alone, symptomatic treatment is needed. If there are no other complications or if it develops in a serious direction, there is no big problem. You can check your blood routine to see if the pneumonia problem is caused by bacteria or viral infection, and then use some symptomatic antiviral or antibiotics to treat it. If there are pneumonia caused by some lung tumor diseases, or tuberculosis problems combined with lung infection, it belongs to a more serious respiratory problem. Serious cases may require surgery or chemotherapy. Also note that if it is only mild, you can do some atomization treatment.
