The fetus is too big is not a blessing, pay attention to Oh!
Fetal changes
In the first trimester (1 to 3 months), the fetus still lives in the maternal pelvic cavity in the womb, and the direct compression of external forces or self-compression will not be very heavy, so the sleeping posture of pregnant women can be arbitrary.
It is mainly to take a comfortable position, such as supine position and lateral position. Poor sleeping posture such as sleeping on your stomach or sleeping with something in your arms should be changed.
In the second trimester (4 to 7 months), care should be taken to protect the abdomen and avoid the direct effects of external forces.
If the pregnant woman has too much amniotic fluid or twin pregnancies, it is necessary to adopt a side-lying sleeping position, which can make the pregnant woman more comfortable, and other sleeping positions will produce symptoms of compression.
If the pregnant woman feels that the lower limbs are heavy, she can take a supine position and slightly raise the lower limbs with a soft pillow.
In the third trimester of pregnancy (8 to 10 months), the decubitudinal position is particularly important during this period. The lying position of pregnant women is important to their own and the safety of the fetus.
It is advisable to take the left recumbent position, which can correct the right rotation of the enlarged uterus, reduce the compression of the uterus on the abdominal aorta and the iliac artery, improve blood circulation, increase the blood supply to the fetus, and benefit the growth and development of the fetus.
However, it is not advisable to take a supine position. Because when lying on the back, the huge uterus compresses the inferior vena cava, so that the amount of blood returning to the heart and the output of the heart are reduced, and hypotension occurs, pregnant women will feel dizzy, panic, nausea, breath holding and other symptoms, and pale, limb weakness, cold sweat and so on.
If the above symptoms occur, the left side should be taken immediately, and the blood pressure can gradually return to normal and the symptoms will disappear.
Weight standards for pregnant women
An increase of 2 kg in the first trimester of pregnancy (within 12 weeks of pregnancy);
5 kg increase in the second trimester (13-27 weeks of pregnancy);
An increase of 5 kg in the third trimester of pregnancy (28-42 weeks of pregnancy) is appropriate, and a total increase of about 12 kg before and after is appropriate.
If you gain more than 20 kilograms throughout pregnancy or weigh more than 80 kilograms, it is a red flag. Obese women are best to lose weight and then become pregnant, and should not lose weight during pregnancy, but should still pay attention to the total daily calorie intake.
