Pulmonary hypertrophy is a condition in which some parts of the body become swollen, enlarged and painful because of a lung disease. Common pulmonary hypertrophy disorders include pulmonary hypertrophic osteoarthropathy. Pulmonary hypertrophic osteoarthropathy is a clinical imaging syndrome that includes pestle and mortar fingers (toes), osteochondritis of the long bones and arthritis, the onset of which is mostly associated with pulmonary lesions. So, how to prevent pulmonary tuberculosis causing pulmonary hypertrophy? The following is a brief introduction: a. Regularity of life. Avoid long-term overwork and mental tension, eat a balanced diet, and exercise appropriately to enhance resistance. Second, to prevent the spread of tuberculosis bacteria. 1, reduce the spread of tuberculosis bacteria, strengthen health education, so that everyone understands the dangers of tuberculosis and the mode of transmission (because it is respiratory infection), and develop the hygienic habit of everyone not to spit anywhere; the sputum of tuberculosis patients should be burned or disinfected with drugs; patients should cover their mouths with handkerchiefs or wear masks when coughing and sneezing, and do not speak loudly in close proximity to others; items used by patients should be frequently disinfected and cleaned The items used by patients should be disinfected and cleaned frequently. 2. Reduce the concentration of tuberculosis bacteria in the environment. Tuberculosis bacteria are easily spread in poorly ventilated and more confined environments (such as winter living rooms, crowded group dormitories or work sheds). Therefore, it is necessary to develop the habit of opening windows regularly to ventilate and let daylight into the room as much as possible. 3, pay attention to isolation, reduce contact with the source of infection. Isolation of patients with bacteriophage tuberculosis should not go to crowded places where people have frequent contact with each other or work. Family members of the patient, in addition to active treatment and frequent ventilation, it is best to live in a separate room, no conditions should also sleep in separate beds.
