Biparietal diameter of fetus at 16 weeks

The development standards of the fetus are different at different stages. Generally, the baby will slowly enter the second trimester at 16 weeks. During this period, the baby's development is very fast. In addition to getting enough sleep, pregnant mothers also need to pay attention to their diet, try to maintain a balanced nutrition, prevent malnutrition in the baby, and be sure to develop good living habits.

Biparietal diameter of fetus at 16 weeks

The standard femoral length for a 16-week fetus is 2.10 ± 0.51', the average biparietal diameter is 3.62 ± 0.58', and the average abdominal circumference is 10.32 ± 1.92'. A 16-week-old fetus is about 12 cm long and weighs 150 grams, which is just the right size to fit in the palm of your hand. His/her reproductive organs have been formed and can continuously inhale and exhale amniotic fluid. Moreover, when the baby is 16 weeks old, the pregnant mother can feel the fetal movement more obviously.

What to look out for during the 16th week of pregnancy

The fetus develops very rapidly at this stage, and the baby will absorb more iron from the pregnant woman's body. At this time, the expectant mother's demand for iron increases nearly 4 times. If the expectant mother has anemia before pregnancy, she is very likely to develop iron deficiency anemia now. The consequence is that the oxygen-carrying capacity of the expectant mother's blood cells is reduced, which causes intrauterine hypoxia of the fetus, resulting in intrauterine fetal death or premature birth. Therefore, it is necessary to supplement enough calcium in time.

Parents don't want to miss any stage of their baby's growth, including when the baby is in the womb. Parents want to know what the baby looks like at each stage. A 16-week-old fetus is already the size of a palm, and fetal movement can be felt. During this period, pregnant women must strengthen nutrition, especially the absorption of calcium, so that the baby can grow better.

Dietary considerations for 16 weeks of pregnancy

1. Increase the intake of various nutrients. Try to meet the needs of rapid fetal growth and maternal nutrient storage to avoid the effects of malnutrition or deficiency on fetal growth and development and maternal health.

2. Increase the intake of staple food. You should choose standard rice and noodles, and eat some whole grains, such as millet, corn, oatmeal, etc. Generally speaking, the daily staple food intake during the second trimester should be between 400-500 grams, which is of great significance for ensuring calorie supply and saving protein.

3. Increase animal food. The high-quality protein provided by animal food is the material basis for fetal growth and maternal tissue growth. In addition, the protein quality provided by beans and soy products is similar to that of animal foods. For families with limited economic conditions, they can choose to eat beans and their products to meet the body's needs. However, the protein provided by animal foods should account for more than 1/3 of the total protein mass.
