Tuberculous pleurisy is a common form of tuberculosis. About one-third of the world’s population is infected with tuberculosis bacteria, and about one-half of China’s population is infected. Many patients can heal on their own without diagnosis and treatment, but this does not mean that they do not need treatment. Most patients who do not receive treatment develop active tuberculosis and even develop severe systemic multi-organ tuberculosis. Tuberculous pleurisy can be divided into dry pleurisy, exudative pleurisy, and pustular pleurisy. Dry pleurisy has no pleural fluid, while exudative pleurisy is a more frequent type in hospitalized patients and requires thoracentesis to draw pleural fluid, which can develop into a pus-filled chest if left untreated or improperly treated. Treatment of tuberculous pleurisy requires timely pleural fluid aspiration to prevent complications, and most importantly, regular anti-tuberculosis treatment for about 1 year, which may require hormone therapy in the early stages. Many patients believe that the absence of pleural fluid is a cure, which is a misconception. Most tuberculous pleurisy can be completely cured, only a small percentage may develop into abscess chest or even need pleural dissection surgery. Some patients do not feel discomfort when they have pleural fluid, but on the contrary, they often feel pain and discomfort in the back of the chest during the process of improvement, and are always afraid of disease recurrence, which may be related to pleural adhesions left after the absorption of pleural fluid in TB pleurisy, especially when breathing deeply. Do not worry too much about this situation, as it may occur years after the disease is cured, especially when the weather changes significantly. In conclusion, don’t worry too much about being infected with TB pleurisy, but treat it under the guidance of a professional doctor and the disease will usually be cured.
