Is it okay to lose weight at 38 weeks pregnant?

Ask
Hello doctor,
I am 38 weeks pregnant. At 37 weeks pregnant, I went to the baby's doctor for 2900g, now I have a regular check-up at 38 weeks pregnant and reduced to 2750g. So the doctor asked me if I lost weight at 38 weeks pregnant? What should I do to improve this situation, doctor? Thank you doctor.

Hello,
To the question “Is it okay to lose weight at 38 weeks pregnant? ", the doctor would like to answer as follows:
Fetal ultrasound is a medical imaging method that helps monitor the fetus quite popular today. Ultrasound technique is to use sound waves transmitted through the uterus, to the placenta and the fetus, the fetus's body will reflect this wave. The computer then translates the sound waves, reconstructing them into black-and-white (2D) or color (3D,4D) images showing the baby's shape, position and movements. There are more than 30 different algorithms used to predict the baby's weight through the form of ultrasound. The parameters will be collected from different locations and used for calculations. This depends on the position of the baby, the stage of pregnancy, the volume of amniotic fluid or the time and angle of the doctor's probe. Therefore, ultrasound is not a completely accurate method to determine fetal weight. This method only helps to predict the baby's weight with an error of 8 - 15%. The largest the fetus is to the last month, the stage near labor, the baby moves deeper into the mother's pelvis, the doctor will have more difficulty in accurately determining the baby's weight.
If the weight of the fetus has decreased through ultrasound, but other indicators of the baby's health such as amniotic fluid volume, middle cerebral artery Doppler index, uterine artery or cardiac oscillation measurement If your pregnancy is within normal limits, you should continue to monitor your pregnancy under the guidance of your doctor. You eat enough nutrients during the day, prioritize foods that are easy to digest and wait for the day of the birth.
