Symptoms of high lactate dehydrogenase up to 325 after lymphoma cure may be the symptoms of certain diseases, such as myocardial infarction, acute and chronic hepatitis, and recurrence of malignant tumors, etc., and one should consult doctor in time to find out the reasons. 1. Myocardial infarction: acute occlusion of coronary artery leads to myocardial necrosis; and lactate dehydrogenase mainly exists in myocytes, when myocardial infarction occurs, it will lead to increased level of lactate dehydrogenase in blood. Therefore, the symptom of high lactate dehydrogenase up to 325 may appear after lymphoma is cured. 2. Acute hepatitis: caused by virus, bacteria, alcohol, autoimmune factors and other factors, resulting in damage to liver cells and dysfunction of liver, causing high lactate dehydrogenase in blood test. Therefore, the symptom of high lactate dehydrogenase up to 325 may appear after lymphoma is cured. 3. Recurrence of malignant tumors: malignant tumors such as stomach cancer, cervical cancer, etc., when malignant tumors develop to middle or late stage and metastasize to the abdominal cavity or thoracic cavity, causing hydrothorax and ascites, and the test of hydrothoracic and ascites puncture will find that the lactate dehydrogenase is elevated. Thus there may be symptoms of high lactate dehydrogenase to 325 after lymphoma cure. Symptoms of lactate dehydrogenase high to 325 after lymphoma cure should seek medical advice and targeted treatment under the guidance of a doctor.
