If you are malnourished in late pregnancy, it may be because you are eating too little or your protein intake is too low, which can cause mild malnutrition, so don’t worry too much at this time. Because mothers are very great and will try to ensure the nutritional needs of the fetus even if they are malnourished themselves. The ability of the fetus to take in nutrients from food is very strong, and the fetus’s ability to take in too much causes the mother’s relative malnutrition, and as a result, when metabolized from the urine, the creatinine urea nitrogen level in the body is relatively low, so it causes a false state of malnutrition. If there is thinness and general weakness with low creatinine urea nitrogen, this is the time to pay attention because excessive malnutrition can affect the development of the fetus. Timely supplementation is needed.
