Sleeping and breath-holding after six months of lung micro-invasive adenocarcinoma surgery is considered to be caused by poor lung function after surgery, metastasis of lung cancer, or complication of infection, etc. According to different causes, respiratory exercises, chemotherapy, targeted and other anticancer therapies, medicines to control infections and other therapeutic measures should be given. 1. Poor function of residual lungs after surgery: generally take deep breathing and other methods for respiratory training, which can improve the symptoms to a certain extent. 2. Lung adenocarcinoma recurrence or intrapulmonary metastasis: evaluate the specific stage, gene and immune status of the patient, and adopt comprehensive treatment plan such as chemotherapy, targeting and immunization to control lung cancer lesions, so as to reduce breath holding. 3. Patients with low immunity combined with lung infection: antibiotics such as moxifloxacin and other broad-spectrum antibiotics can be given to control lung infection, so as to reduce breathlessness. It is recommended that the patient should consult the doctor in time, improve lung function, chest CT, blood routine and other tests to clarify the cause of the disease, and take treatment measures according to different causes.
