What is the standard fetal weight at 23 weeks of pregnancy?

The weight of the fetus at 23 weeks of pregnancy is about 400g. The growth rate of the fetus in the uterus is not the same and may vary from one pregnant woman to another due to individual differences and consideration of nutritional absorption and other reasons. At 23 weeks of pregnancy, the average value of fetal biparietal diameter is 5.80±0.44cm, the average value of femur length is 4.21±0.41cm, the average value of abdominal circumference is 17.90±1.85cm, the facial lips and eyebrows are already visible, the retina has a weak visual ability, the permanent dental embryo develops, various organs begin to develop, subcutaneous fat begins to be deposited, and the weight of pregnant women shows a steady increase. If there is no abnormality, try to do a maternity check once a month to measure the height, weight, uterine height and abdominal circumference of the pregnant woman, and do ultrasound examination to observe the development of the fetus. In the middle of pregnancy, the fetus needs more nutrition, so pay attention to supplementing iron, calcium, DHA and so on, and at the same time, ensure that the body has enough protein and vitamins, so do not be partial. However, do not add too much at one time, so as not to have too much nutrition, which will make it difficult to control the weight in the second trimester and cause difficulties in delivery.
