If a patient often experiences pericardial effusion, it is recommended that they visit a hospital for a cardiac echocardiogram, as this pericardial effusion is necessarily connected to the heart. Although it is not greatly related to diet, if the patient enjoys eating salty foods, it can still have a certain impact. It is advised to choose a diet low in salt, fat, and sugar, especially limiting sodium intake, because consuming too much salt can exacerbate fluid and sodium retention, leading to pericardial effusion. Currently, treatment mainly focuses on symptomatic treatment, and early use of medications. Diuretics can be used to help alleviate the patient's current condition.
