Question

Is a biparietal diameter of 91mm at 37 weeks pregnant considered large?

Answer

A biparietal diameter of 91mm at 37 weeks pregnant is within the normal range. Normally, the biparietal diameter at 37 weeks of pregnancy ranges from 89 to 91mm. Therefore, the size of the baby’s head is normal, and there is no need to be overly concerned. In the later stages of pregnancy, attention should be paid to a balanced diet, consuming more fresh fruits and vegetables, which helps with the growth and development of the fetus. If planning for a natural birth, moderate exercise can be appropriate.
