If one side of the lung is destroyed but the right lung is still alive, it can be treated by general treatment, oral drug treatment or surgery. 1. General treatment: patients with one lung destroyed by TB should pay attention to rest, strengthen nutrition, avoid exertion, prevent infection, and give oxygen to improve the symptoms of respiratory distress. 2. Oral drug treatment: patients with one side of the right lung destroyed by tuberculosis still have to continue to take isoniazid, rifampicin, streptomycin and other anti-tuberculosis drugs to control the condition and prevent the spread of mycobacterium tuberculosis. 3. Surgery: Pneumonectomy is often used, which is a surgical resection of the damaged lung with low lung function, removing all necrotic foci due to tuberculosis, so as to achieve the purpose of controlling tuberculosis infestation of lungs, restoring patients’ lung function, and improving patients’ quality of life. Patients with one side of the lung damaged by tuberculosis should go to the hospital in time and under the guidance of the doctor for regular treatment.
