The biparietal diameter is the widest measurement of the fetus’s head, which is included in all pregnancy tests. The biparietal diameter gives an idea of the development of the fetus.
If the biparietal diameter of the fetus is small within one week, it is mostly a normal phenomenon, and you need to follow up the change of the biparietal diameter of the fetus regularly during the labor and delivery checkups.
If the biparietal diameter of the fetus is smaller than two weeks, the pregnant woman should pay special attention to it. If the biparietal diameter of the fetus is smaller than two weeks, it is called “intrauterine growth restriction”, and the first thing to do is to suspect whether there is any disease that affects the growth of the fetus. Doctors will usually recommend that pregnant women be hospitalized to find the cause of the problem and treat the symptoms with amino acids, glucose and other nutritional supplements.
Therefore, pregnant women should not worry too much when they find that their baby’s biparietal diameter is small. They should rule out any disease of the fetus under the guidance of the doctor and then strengthen the nutritional treatment.
