Cirrhosis with hydrothorax (fluid in the chest cavity) needs to be clarified whether the hydrothorax is caused by cirrhosis or not, and should be treated with symptomatic treatments, such as limiting the intake of sodium and water and using diuretics. 1. Cirrhosis-induced hydrothorax: Cirrhosis-induced hydrothorax is usually formed on the basis of ascites, which is caused by the leakage of ascites into the thoracic cavity through the diaphragm. At this time, it is necessary to limit the intake of sodium and water; use diuretics such as furosemide, etc.; when the pleural effusion reaches a certain amount, it will cause respiratory distress and other symptoms, and also need to be treated by thoracentesis. If necessary, surgical treatment will be chosen. 2. Pleural effusion caused by other reasons: due to lung inflammation, tuberculosis, lung cancer and other diseases can cause pleural effusion, so if cirrhosis has pleural effusion, you need to go to the hospital to have a relevant examination, such as pleural fluid test, chest CT, blood routine and so on, so as to make clear the cause of the disease, and then treat the cause of the disease, such as anti-inflammatory, anti-tuberculosis and surgical treatment and so on. Cirrhosis chest water need to immediately go to the hospital for relevant examination, under the guidance of the doctor to take medication.
