Is it normal for the fetus to have a small biparietal diameter for two weeks

The biparietal diameter value is small for two weeks, which is mostly abnormal. It may be caused by fetal growth restriction. It may also be caused by wrong evaluation of gestational age. It is recommended to re-evaluate gestational age and observe fetal growth and development. If fetal growth restriction exists, amino acids, fat emulsion, vitamins, oxygen and other methods can be given. Daily diet should be balanced and reasonably matched.
