Pregnant women pay special attention to the development of their babies during pregnancy. Because if there are any special circumstances in the baby's belly, it is necessary to detect them in a timely manner in order to take effective treatment and ensure the healthy development of the child. So understanding the relevant situation is very important. So what is the fetal development at the 21st week of pregnancy? Let's study hard together.
What is the fetal development at the 21st week of pregnancy
The baby is 21 weeks old. This week, the fetal length is about 16-18 centimeters and the weight is 300-350 grams. At this time, the fetal weight begins to increase significantly. The baby's eyebrows and eyelids are clearly visible, and their fingers and toes are also beginning to grow toenails. If you are pregnant with a girl, her vagina has already formed and will continue to develop until birth. This little guy now looks slippery, with fetal fat covering his entire body, which can protect the skin of the fetus. Many babies still have these white fetal fat residues on their bodies at birth.
What are the precautions for fetal development in the 21st week of pregnancy
1. In mid pregnancy, although your sleep condition has improved, as your energy recovers, you may not need to sleep as much anymore. During this period, your feelings and sleep have improved significantly. You can start consciously doing some exercise, which can improve your physical and mental health and help you sleep better at night.
2. Anemia in pregnant women is a nutritional deficiency that occurs during pregnancy. Mild anemia in pregnant women does not have a significant impact on the fetus, as iron is transported unidirectionally in the placenta and preferentially supplied to the fetus. When severe anemia occurs, it can lead to delayed development, intrauterine hypoxia, premature birth, or stillbirth due to placental ischemia and hypoxia.
There are many issues that pregnant women need to pay attention to when carrying their babies, as the health of the baby depends on whether the mother's body is healthy. Some issues that pregnant women need to pay attention to in their daily lives must be known and understood, which are very helpful for the health of the baby. So if you really care about these issues, it's best to accumulate more experience in life.
