Low albumin on liver function tests is often caused by poor liver synthesis; or excessive loss and increased consumption of albumin, and is commonly seen in malignant tumors, severe tuberculosis, malnutrition, acute hemorrhage, severe burns, thoracic ascites, kidney disease, and late pregnancy. Low albumin can be improved by dietary supplements and intravenous infusion. If the albumin is mildly low, you can first raise it through diet, such as eating a high-quality protein diet, such as milk, lean meat, fish, shrimp, etc. You can also eat a moderate amount of food rich in vegetable protein, such as tofu and soy products. If the decrease in albumin is significant, in addition to dietary supplements, oral protein powder can also be taken to supplement albumin. If albumin decreases further, below 20g/L, you need to go to the hospital for intravenous infusion of human albumin to alleviate the problem. Since human albumin is a plasma product, you should closely observe whether infusion reactions and allergic reactions occur during the infusion process. In addition, there are many reasons for the decrease in albumin, and the root cause of improvement is to identify the cause and treat it according to the cause in order to bring albumin back to normal levels.
