How much can a normal birth weigh if the pelvis is small?

Many female friends feel that their pelvis is too small, which may lead to difficulties in childbirth. So they want to know how many kilograms of baby they can give birth to naturally with a small pelvis. Pregnant women can actually consult a gynecologist about what kind of delivery method is suitable for them, because there is no clear and unified information on how many kilograms a baby can be born naturally if the pelvis is small, and relevant examinations need to be done before reasonable suggestions can be made.

There is no uniform standard for how much weight a baby can give birth naturally if the pelvis is small. Generally, a baby can give birth naturally if the pelvis is small, but if it is really small, you can choose a caesarean section after the doctor's evaluation to ensure safety. However, the delivery method of some women has little to do with the pelvis, because it also depends on the force applied to the birth canal of each woman. If the strength of the pelvis is relatively strong, then natural delivery will be more convenient.

If the pelvis is relatively small, you can do pelvic training activities, such as using a yoga ball or hula hoop, etc., which have a very good activating effect on local muscles and bones. When giving birth to a baby, you can let the baby be born quickly to exert force, which can also reduce various negative injuries.

In addition, a small pelvis is not actually a bad thing. If you are not very reassured, you can go to the hospital regularly for pelvic examinations and fetal position. Although the pelvis is small, the baby's surrounding activities may be restricted. But as long as everyone takes good care of it and maintains good hygiene habits, it should be able to recover to a good condition.

The relationship between pelvic size and delivery mode

Does pelvic size and shape affect childbirth? The answer is yes, the size of a woman's pelvis has a certain impact on childbirth. If the pelvis is large, it will be easier to give birth naturally. Otherwise, cesarean section is recommended. However, whether a natural birth is possible depends on the mother's physical condition. The size and shape of the pelvis are important factors in determining whether a vaginal birth is possible. Pelvic abnormalities can cause abnormal fetal position and relative or absolute cephalopelvic disproportion, leading to dystocia.

Having a narrow pelvis is dangerous during childbirth because the vagina has a certain degree of elasticity, and the pregnant woman's pelvis is only that big and cannot expand further, so the baby's head still cannot come through during delivery. If you insist on having a natural birth, the doctor may use other auxiliary tools, which may not only hurt the baby but also cause fractures. Therefore, if you have a narrow pelvis, you should be mentally prepared for a caesarean section in advance.

How to tell the size of your pelvis

How to determine the size of the pelvis? Here are some methods and data for everyone, expectant mothers can use them as a reference.

Interiliac spine diameter: The pregnant woman lies on her back and uses a pelvic measuring tape to measure the distance between the outer edges of the two anterior superior iliac spines. The normal value is about 23 to 25 cm.

Iliac crest diameter: The pregnant woman lies on her back and measures the widest distance between the outer edges of the two iliac crests. The normal value is about 25 to 28 cm.

Sacropubic external diameter: The mother lies on her side with her upper leg straight and her lower leg bent. The distance from the midpoint of the upper edge of the pubic symphysis to the lower part of the spinous process of the fifth lumbar vertebra is measured. The normal value is 18 to 20 cm. This diameter can indirectly infer the size of the anterior-posterior diameter of the pelvic inlet.

Intersciatic tuberosity diameter: the distance between the inner sides of the two ischial tuberosities, with a normal value of 8.5 to 9.5 cm, representing the transverse diameter of the pelvic outlet.

The biparietal diameter is most closely related to your transverse birth canal diameter. The biparietal diameter is the largest part of your child, while the transverse birth canal diameter is the smallest part of the birth canal.
