Generally speaking, when examining organs such as liver, gallbladder, pancreas and peritoneum, you need to let yourself go on an empty stomach before the examination, because fasting can avoid too much food in the intestine. If these foods exist in the intestine, it is easy to produce gas and interfere with ultrasound. Moreover, if there is food in the gallbladder, the bile in the gallbladder will not be full enough, so the accuracy of the examination will drop.
So, before checking these parts, you should let yourself have an empty stomach. When patients do these parts that need fasting examination, they can arrange these examination items in the morning, so that the dinner the day before can be lighter, and don't eat by yourself after 10, which can achieve the purpose of fasting examination.
