Thickness of breath after lung nodule surgery can gradually return to normal in about one month, but the exact recovery time varies depending on the size of the nodule and the variability of the organism. Lung nodule size and location are different, the choice of surgery is also different, so the size of the lung tissue needs to be removed during lung nodule surgery is also different, after the removal of lung tissue recovery of lung function will take quite a long period of time. If the patient’s lung nodule is relatively small and the body’s ability to recover is relatively strong, the speed of recovery is relatively fast, and the respiratory function can be returned to normal within one month; however, if the patient’s body is relatively weak or the area of the surgical trauma is relatively large, the recovery time required will be a bit longer. If the patient still has obvious shortness of breath, cough and other symptoms about one month after the lung nodule surgery, it is recommended to go to the hospital for lung CT examination to clarify whether there is a lung infection or pleural effusion, etc., and if the diagnosis is confirmed, it is necessary to intervene in a timely manner, to promote the recovery of lung function after the lung nodule surgery, so as to avoid the delay of the disease and aggravation of the uncomfortable symptoms.
