Introduction
If a pregnant woman is in poor physical condition and has a severe case of low pelvis, with an excessively short anteroposterior diameter of the pelvic inlet that significantly restricts fetal passage, the risk of natural childbirth may increase. Natural delivery is generally not recommended in such cases. Pregnant women should undergo regular prenatal checkups during pregnancy and closely monitor fetal growth and development as well as their own health condition.

In general, vaginal delivery refers to natural childbirth. Whether a woman with a low pelvis can deliver naturally depends on her specific physical condition. If the pregnant woman is in good health, she may generally be able to deliver naturally despite having a low pelvis; however, if her health is poor, natural delivery is usually not advisable. The details are as follows:

If the pregnant woman is in good physical condition and although her pelvis is low, the measured diameters—including the anteroposterior and transverse diameters of the pelvic inlet, the mid-pelvis, and the pelvic outlet—fall within normal ranges and provide sufficient space for the baby to pass through, then natural delivery may be attempted under medical evaluation if deemed safe.

However, if the pregnant woman is in poor health and has a significantly low pelvis, particularly when the anteroposterior diameter of the pelvic inlet is too short and clearly restricts the baby's passage, the risks associated with natural delivery may increase, making it generally inadvisable.

Pregnant women should undergo regular prenatal checkups during pregnancy to closely monitor fetal development and their own health. Prior to delivery, they should have thorough discussions with their doctors to jointly determine the most suitable birthing plan.
