Patient's question:
I am almost three months pregnant. My mom said that at three months, I need to go to the hospital for a prenatal check-up to see if the fetus is healthy. She mentioned that an ultrasound needs to be done. Previously, when getting an ultrasound, I needed to hold my urine, and I also heard that I needed to fast. I don't know if this has changed now. I plan to go to the hospital for a check-up tomorrow morning.What kind of help do I need: Do I need to fast for the ultrasound?
Doctor's answer:
Analysis of the condition: B requires fasting and water abstinence. The evening meal before the examination should consist of light, low-fiber foods, followed by a night of fasting. On the day of the examination, breakfast and water should be avoided to ensure the morning examination is performed on an empty stomach. This is primarily to reduce the interference of gastrointestinal contents on the ultrasound beam and ensure sufficient bile is present in the gallbladder and bile ducts. Sometimes, even after fasting, some patients still have a large amount of gas in their gastrointestinal tract. These patients should take flatulence tablets orally 1-2 days before the examination, which can help eliminate intestinal gas.
