How big is the belly at 16 weeks of pregnancy?

The baby is particularly happy at 16 weeks of pregnancy. He can make various movements, such as sucking his thumb, stretching his feet, squinting his eyes, and even somersaults. What's exciting is that you can hear the first fetal movement, which will make you intuitively feel the presence of the baby. Your baby is growing rapidly and you may be prone to anemia. So supplement your nutrition and grow with your baby! Let’s take a look at how big the belly is at 16 weeks of pregnancy.

Fetal development

1 The fetus is about 16cm long from head to hip and weighs about 110g. The mean biparietal diameter was 3.62±0.58 cm, the mean abdominal circumference was 10.32±1.92 cm, and the femur length was 2.10±0.51 cm.

2 The fetus' arms and legs are fully developed, the joints begin to move, hair begins to grow on the fetus's head, the stomach begins to secrete digestive juices, and the kidneys begin to secrete urine. Now the circulatory system and urethra are in full working order, the fetus's lungs are also starting to work, and he is able to continuously inhale and exhale amniotic fluid.

3 What’s even more surprising is that you will feel the fetal movement more obviously this week, and sometimes there will be some tenderness. These are normal reactions and there is no need to worry.

Second mother changes

You are 16 weeks pregnant. Now you have gained about 2kg in weight, your uterus weighs about 250g, and this week your uterus is about halfway between the pubic bone and your belly button. Due to the increase in blood volume and amniotic fluid, the growth of the placenta and fetus, and the enlargement of breasts, all of these will cause your weight to gradually increase. Your lower abdomen has bulged, and you look "very pregnant."

Three Nutrition Tips

1 At this time, the mother will feel the following physiological symptoms: high energy, swollen breasts, increased appetite, and due to the weakened digestive system function, indigestion and constipation are prone to occur. After a meal, the mother's blood sugar level will increase, and the baby will be "full" and have enough energy, so fetal movements will become more frequent than before meals.

2 Now is the period when the baby's tooth roots are growing. Pregnant mothers should eat more calcium-containing foods to help the baby grow strong tooth roots. White sugar has the adverse effect of depleting calcium and can easily make people fat. Pregnant mothers can use brown sugar instead of white sugar. The calcium content in brown sugar is twice that of the same amount of white sugar, and 1 times that of white sugar. It also contains a variety of nutrients needed by the human body. It has the effects of invigorating qi, tonifying the middle, digesting food, and strengthening the spleen and warming the stomach.

The above introduces the changes in the belly during 16 weeks of pregnancy. During pregnancy, due to changes in physical constitution, the body will always show some disease symptoms that did not exist before pregnancy, and prurigo gravidarum is one of them. The symptoms of prurigo during pregnancy are symmetrically distributed papules on the skin. Pregnant mothers will feel unbearable itching, which is more severe at night. Pregnant mothers should take good care of themselves when they experience prurigo during pregnancy.
