How big is the fetus at 20 weeks?

A 20-week-old baby weighs about 630 grams and is about 30 centimeters long. The fetal biparietal diameter is approximately 4.7 cm to 5.0 cm, and the femoral length is approximately 3.1 cm to 3.3 cm. The 20th week of pregnancy is the best time to remove a malformed fetus. You can choose to do a four-dimensional ultrasound to examine the fetal skull, face, internal organs and limb development. At the same time, eat more foods containing iron to prevent anemia. You should go out more often to get some sun exposure and supplement vitamin D to promote calcium absorption.

At 20 weeks of pregnancy, the fetus is between 14-16.5cm long and weighs about 250g. The limbs are well developed and the hair is growing rapidly. The fetus can now swallow amniotic fluid, and the kidneys can already produce urine. The baby's senses begin to develop rapidly, and the taste buds, smell, hearing, vision and touch have entered important stages of development.

In order to protect the skin, lipids began to be produced, slim eyebrows grew, and his eyes were able to move, although they were still closed. The bottom of the uterus is already parallel to the belly button, and the height of the uterus is about 16-20cm. It is important to go to the hospital for a four-dimensional examination in time at 22-26 weeks to rule out major deformities. In order to provide the fetus with a better growth environment, pregnant women must supplement the necessary nutrients after 20 weeks of pregnancy. The balance of nutrients such as protein, vitamins, calcium, iron, zinc, selenium, etc. must be maintained to prevent picky eating. In order to prevent pregnant women from suffering from anemia, proper absorption of iron is very important. If pregnant women have increased secretions or sweat a lot, they must take a shower every day or change their underwear in time to avoid bacterial infection.

The above are some changes that occur in the 20th week of pregnancy. I hope that mothers who are preparing for pregnancy will have a proper understanding of these simple knowledge and can clearly understand whether the changes that occur in such a situation are normal. It is very important to allow the baby to have a comfortable growth environment, which can also play a certain auxiliary role in the baby's future health.
