What are the reasons for low serum albumin?

Sometimes when you are sick or have a fever and go to the hospital, the doctor will ask you to draw blood for tests, which includes blood tests. Sometimes the test result shows that the serum albumin is low, which is caused by liver dysfunction, protein loss, and malnutrition. If a child has low serum albumin, it is recommended that you pay attention to nutritional intake and learn in detail about the reasons for low serum albumin.

First, what are the reasons for low serum albumin?

Reason 1 for low protein: water and sodium retention caused by various reasons, which dilutes the plasma, or excessive intravenous injection of hypotonic solution leads to a decrease in total protein in plasma.

The second reason for low protein: liver dysfunction, which leads to reduced protein synthesis in the liver, with a significant decrease in albumin.

The third reason for low protein: protein loss, such as severe large-area burns, large amounts of plasma exudation, and massive bleeding; in nephrotic syndrome, protein in the urine is lost for a long time; in ulcerative colitis, a certain amount of protein may be excreted with the feces.

The fourth reason for low protein: malnutrition or increased consumption, such as long-term insufficient protein in food or malabsorption caused by chronic intestinal diseases, chronic wasting diseases such as tuberculosis, malignant tumors, cirrhosis, etc. In view of the above reasons, targeted treatment should be provided according to different causes. It is recommended that you breastfeed your child on demand, let him drink an appropriate amount of water, check trace elements regularly, and supplement them appropriately based on the test results.

Second, the reasons for the decrease in total protein include : damaged liver cell function, malnutrition, kidney disease, massive bleeding, water and sodium retention, some wasting diseases such as tuberculosis, hyperthyroidism, malignant tumors, and a very small number of people are naturally low in total protein. Your total protein value is basically normal, don't worry. Under normal circumstances, the total protein content in the human body is about 65-86g/L. A high total protein level does not mean anything, because there are many reasons for high total protein levels, such as any chronic infection, such as pharyngitis, rhinitis, cholecystitis, pelvic inflammatory disease, etc. The antigens produced by these pathogens can stimulate lymphocytes, thereby causing high total protein levels.

What is the reason for low serum albumin? The normal value of blood albumin in different age groups is also different. Generally, the normal value of albumin for newborns is 28-44g/L, the normal value of albumin after 14 years old is 38-54g/L, the normal value of albumin for adults is 35-50g/L, and the normal value of albumin after 60 years old is 34-48g/L. Decreased albumin is common in liver damage such as cirrhosis, malnutrition, chronic wasting disease, diabetes, nephrotic syndrome, etc. Prealbumin is a plasma protein mainly synthesized by the liver. In addition to participating in the transport and regulation of vitamin A and thyroxine in the body, it also has immune-enhancing activity and potential anti-tumor effects.
