What is the standard for the biparietal diameter of a 27-week fetus?

What most mothers are most concerned about after giving birth is whether their children's development has reached the actual standards. If it has not reached the standards, they should pay more attention to it. Many mothers are concerned about the standard of biparietal diameter of a 27-week fetus. Today, there are experts in this field here. Let’s listen to what they say! I hope that through the detailed content below, everyone can understand this issue.

At 27 weeks of pregnancy, the average biparietal diameter was 6.98±0.57", the average abdominal circumference was 21.81±2.12", and the femur length was 5.10±0.41. By the 27th week of pregnancy, the baby weighs about 900 grams and is 38 centimeters tall. At this time, short hair has grown on the fetus's head, and its eyes are open and closed, and its sleep cycle is very regular. If you are having a baby girl, her labia minora have begun to develop. The boy's testicles have not yet come down.

1. Fetal development standards at 27 weeks of pregnancy

Your baby is now gaining height and weight at a steady pace each week. He now weighs about 900 grams and is 38 centimeters tall. At this time, short hair has grown on the fetus's head, and its eyes are open and closed, and its sleep cycle is very regular. If you are having a baby girl, her labia minora have begun to develop. The boy's testicles have not yet come down.

Fetal brain activity is already very active at 27 weeks. Characteristic grooves and convolutions begin to appear on the surface of the cerebral cortex, and brain tissue grows rapidly. You may feel some rhythmic movements from your baby, which is because your baby often hiccups. Each one usually lasts only a few minutes. Don't worry that he will feel uncomfortable because of hiccups!

2. Physical condition of expectant mothers at 27 weeks of pregnancy

The weight of the baby puts pressure on your back, causing severe pain in your lower back and legs. At the end of the second trimester, the uterus is about 7 cm above the navel, and if measured from the pubic symphysis to the bottom of the uterus, it is about 27 cm.

During this week, your amniotic fluid level drops by half. You may even see a little bulge in your belly from your baby's larger bony knees and elbows as he kicks and turns. If someone is staring at you, they will be able to see it too. Now, you may also be developing stretch marks on your chest and abdomen. It is difficult to wash your feet and tie your shoelaces by yourself. Your leg cramps will likely get worse. Leg cramps usually occur at night, but they can also occur during the day. Stretching your calf muscles, straightening your toes forward, and then hooking your feet toward your shins can provide some relief.

This is the end of the introduction to the standard of biparietal diameter of a 27-week fetus. I hope the explanation in the above article can help you understand this common sense in depth. When the baby reaches 27 weeks, we need to check whether the baby has met the standard. If not, it means that the nutrition of the food he eats normally is not enough, and he needs to strengthen his nutrition in the future.
