When the serum pre-albumin is low, you must pay attention to correct your eating habits and pay attention to increase the quality protein, which comes from foods such as sea cucumber, milk, eggs, tofu and fish. By supplementing with high quality protein, you can increase the liver to synthesize more protein and allow the serum albumin to rise gradually. Low serum pre-albumin can be seen in times of malnutrition, in patients with advanced malignancy or in chronic liver diseases such as cirrhosis, liver cancer, obstructive jaundice or chronic active hepatitis. On the one hand, attention should be paid to the supplementation of high quality protein, and on the other hand, attention should be paid to the improvement of liver function. Commonly used liver-protective and anti-inflammatory drugs include diammonium glycyrrhizate enteric capsules, glycopyrrolate injection or reduced glutathione.
