How big is a fetus at 18 weeks?

As a woman's pregnancy progresses, the development of the fetus in her belly will also change, so regular physical examinations are necessary to monitor the development of the fetus and avoid developmental delays. The fetus can already move at 18 weeks, and the approximate length of the fetus can also be seen from the test report, so pregnant women should also appropriately strengthen nutrition to promote development. So how big is a fetus at eighteen weeks?

1. At 18 weeks of pregnancy, the fetus begins to move frequently. At this time, the fetus is close to 20 cm in length and weighs 200 grams. The nail pads of the fetus's fingernails and toenails have been formed, and fingerprints have begun to appear. His little eyes have moved to the correct position, his ears have moved up toward the head, villi have begun to cover his entire body, and his intestines have begun to move. During this period, Down syndrome screening should be done. It is recommended to eat a normal diet, ensure balanced nutrition, maintain appropriate trace elements and calcium, and have regular prenatal check-ups.

2. According to the standards, at 18 weeks of pregnancy the fetus is approximately 20 cm long and weighs approximately 250 grams. The pregnant woman has already felt the fetus move. Nowadays, pregnant women are consciously strengthening their nutrition, so the fetus is generally larger than the standard weight. Try to diversify your diet during pregnancy, eat more foods high in calcium, and pay attention to fetal movements, no less than 10 times every 12 hours and no less than 3 to 5 times per hour. At 18 weeks of pregnancy, the blood vessels under the thin skin of the fetus are clearly visible, and the ears have grown to their normal position. His (her) chest bulges and sinks from time to time. This is a sign of fetal breathing, but it is amniotic fluid, not air, that flows in the fetus's mouth.

3. The baby's lungs are developing, but the alveoli are not yet mature and cannot work. The pads on the fetus's fingertips and toes have formed. At week 18, the fetus begins to move frequently. During this week, the fetus' eyes, which were originally tilted to the sides, begin to focus forward. The fetus's bones have become almost rubbery cartilage and are beginning to harden. The fetus is nearly 14 cm long and weighs about 200 grams.
