It is not necessary to have an empty stomach to check the fetal heart and fetal buds, but if it is an abdominal ultrasound, you need to hold your urine.
Fetal heart and fetal buds are mainly checked by ultrasound, including abdominal ultrasound and vaginal ultrasound, usually around 7-8 weeks of pregnancy, when the fetal heart and fetal buds have already been generated, and can find out whether the fetal heart and fetal buds are normal or not, ultrasound does not need to fast, and the results of the ultrasound will not be affected after eating.
Fetal heart and fetal buds can be detected by abdominal ultrasound and vaginal ultrasound. In the case of vaginal ultrasound, the bladder should be emptied before the examination, and the examination can be done directly, but in the case of abdominal ultrasound, it is necessary to leave urine, because only after the bladder is full can we see the embryo clearly and understand the development of the embryo.
After pregnancy, women should follow the doctor’s instructions for regular checkups to monitor the development of the baby, and if there are any uncomfortable symptoms, they should consult the doctor in time.
