Patient's question:
I have an itchy lower body, and my underwear is always yellow. What's going on? Does morning sickness have anything to do with constitution?Doctor's answer:
There is a certain relationship. Nausea and vomiting during pregnancy are indeed related to constitution and genetics to some extent. Some people have no nausea and vomiting at all, while others may vomit until birth—it varies from person to person.A prenatal ultrasound is recommended between 22-28 weeks to screen for major fetal abnormalities. A color Doppler ultrasound is definitely necessary. You can choose a 2D or higher-resolution color Doppler ultrasound, but a fetal heart ultrasound is not a mandatory procedure. It is only required if any issues are detected, at which point further fetal heart ultrasound testing would be needed.
