If a pregnant woman has hypoproteinemia, the patient needs to see what the exact value of albumin is. If the patient’s albumin level is below 30 g/L, the patient is considered to have hypoproteinemia, which may cause generalized swelling, as well as the possibility of peritoneal and pleural effusion. Especially for pregnant women, the high negative pressure will compress the patient’s diaphragm to elevate, which will further induce pulmonary atelectasis and increase the patient’s abdominal distension, and more seriously, may cause other accidents in the patient. For women with hypoproteinemia during pregnancy, the first step is to find the cause, whether it is due to malnutrition, poor feeding, or excessive loss due to other diseases. Treatment should be based on the cause. If it is due to disease, the primary disease should be actively treated, and if malnutrition is present, the structure of the diet should be adjusted.
