Is it necessary to fast before a B-ultrasound examination?

Whether fasting is required for B-ultrasound examination depends on the examination site. Generally speaking, some abdominal examinations, such as the examination of organs such as the liver and gallbladder, need to be performed on an empty stomach to reduce the interference of food or gas in the gastrointestinal tract on the imaging quality and avoid affecting the test results. However, fasting is not required for gynecological B-ultrasound examination. When undergoing a B-ultrasound examination, it is important to adjust the diet and avoid eating foods that are prone to produce gas, such as milk and sweet potatoes, as these foods can easily produce gas and hinder the penetration of ultrasound, resulting in unclear images of the organs being examined. Additionally, when undergoing a B-ultrasound examination, it is recommended to wear loose-fitting clothing, which can help save time during the examination and also relax the already tense mood. Excessive tension may affect the effectiveness of the examination, so it is important to cooperate with the doctor during the examination. Finally, some B-ultrasound examinations require holding urine, so it is advisable to prepare several bottles of mineral water. After all the preparations are made, the examination will be smoother.
