How big is the baby at 20 weeks of pregnancy

Patient's question:

No

Doctor's answer:

At 20 weeks, the fetus is about 16-25 cm long and weighs about 250-300 grams. The fetus has grown hair on its head. Teeth are developing. The limbs are well-developed. Immune antibodies are transferred from the mother's blood to the fetus, helping the baby resist diseases in the early period after birth. The sensory organs of the fetus begin to develop rapidly by region. Neurons divide into different senses. Taste, smell, hearing, vision, and touch all begin to develop in specialized areas of the brain from now on. The growth of neuron numbers starts to slow down, but the connections between neurons begin to increase, and the neural connections that form memory and thinking functions are also increasing.
At this stage, you need to focus more on enhancing your nutrition. The loss of appetite in the early stages of pregnancy has long since disappeared. You will experience a significant increase in appetite during this phase and should try to eat a variety of nutritionally balanced foods, avoiding overeating. Overeating can increase the difficulty and pain of delivery, as well as easily lead to symptoms such as high blood pressure and diabetes. It also has no positive effect on the development of the fetus. Therefore, a scientific diet is extremely important.
