Low protein after childbirth is generally considered to be a result of low protein intake and consumption during pregnancy due to the growth of infants and children. After the birth of a child, if the protein is still low, it is necessary to consider whether the woman is malnourished and does not eat enough. In this case, protein supplements, such as fish, beef, eggs, etc., can be actively given. If protein is still low after active supplementation, women need to be further examined to see if there are other causes of protein decline. In addition, some cases of cirrhosis and liver insufficiency lead to decreased synthesis of albumin by the liver, which can also lead to low protein. Women need further tests to confirm the cause of the low protein.
