Introduction
Typically, the normal biparietal diameter (BPD) of a fetus at 18 weeks of gestation is 4.25±0.53 cm. Fetal development within this range is generally considered healthy and normal. A significant deviation from this normal value may indicate unhealthy fetal development, requiring timely medical consultation. It is recommended to take medications such as folic acid tablets and calcium carbonate tablets under the guidance of a physician to improve the condition.

Biparietal diameter measurement is a common prenatal examination that pregnant women undergo to assess the transverse diameter of the fetal skull and evaluate fetal development. At 18 weeks of pregnancy, a BPD of 4.25±0.53 cm falls within the normal range. A significant deviation from this value may indicate unhealthy fetal development, and prompt medical consultation is advised. Under a doctor's guidance, supplements such as folic acid tablets and calcium carbonate tablets may be recommended to support improvement.
Pregnant women are advised to consume foods rich in vitamins, protein, calcium, folic acid, and other essential nutrients during pregnancy, which supports both fetal development and maternal health. Including fresh fruits, vegetables, eggs, milk, and similar nutritious foods in the diet is beneficial. Additionally, engaging in moderate exercises such as prenatal yoga or aerobics can help improve physical fitness, boost immunity, and support healthy fetal development.
