Femoral length standard for full-term fetus

One month into the pregnancy, the fetus is developing at a critical time. At this moment, pregnant women must pay attention to diet and health care, get enough rest, maintain an optimistic and cheerful attitude, and do moderate exercise, all of which will help the fetus to develop better. Another thing to note is that in terms of diet, try not to eat high-fat and high-calorie foods to avoid excessive obesity.

What is the biparietal diameter and femur length of a full-term fetus?

The standard for biparietal diameter of a 12-week fetus: The fetus grows to 4.58 cm, the external genitalia begin to develop, any deformities can be revealed, and the calcification of the skull becomes more complete. The skull halo is clear, the biparietal diameter can be measured, obvious deformities can be diagnosed, and the internal organs tend to become more complete afterwards.

What to do if the fetus's biparietal diameter is too large

1. The larger biparietal diameter of the fetus is a sign of larger fetal development, which is directly related to the good nutrition and low activity level of the expectant mother. It shows that the adequate nutrition of the expectant mother has caused the larger development of the fetus. This is a common symptom nowadays, so there is no need to worry. As long as there is no abnormality in the fetus's head, you can rest assured.

2. However, if the biparietal diameter of the fetus is too large, the first thing to consider is hydrocephalus. It is recommended to pay attention to checking the fetal brain during B-ultrasound to rule out the possibility of abnormal development of the baby.

What to do if the fetus's biparietal diameter is too small

The biparietal diameter of the fetus is also directly related to the nutritional status. A small biparietal diameter may be caused by irregular menstruation, inaccurate gestational age or errors in B-ultrasound measurement. If there are no obvious developmental abnormalities, there is no need to worry too much. It is recommended to pay attention to the regularity of life and diet, pay attention to strengthening nutrition, eat more high-protein foods, and have regular physical examinations.
