In general, patients basically return to normal about 1 month after lobectomy, and can engage in general physical activities after 3 months. After lobectomy, patients should pay attention to a light diet, avoid the intake of spicy and stimulating foods, avoid stimulation by tobacco and alcohol, pay attention to warmth, avoid getting cold, and prevent respiratory tract infections. Patients can carry out appropriate respiratory function rehabilitation training to gradually improve lung function. The respiratory function of the affected side will be reduced after lobectomy, and the compensatory function of healthy lung tissue needs to be enhanced to meet the needs of the body’s respiratory function, to meet the body’s continuous respiratory movement of absorbing oxygen and exhaling carbon dioxide, so that the process of metabolism can be carried out normally.
