It is possible to eat before having a liver puncture. Since liver puncture examination takes the way of local anesthesia, fasting is not strictly required before the examination, and the examiner can eat as needed before the operation. However, if there are other related tests such as liver function and abdominal ultrasound on the day of the liver puncture, the patient should follow the doctor’s instructions to prepare for fasting so as not to affect the results of the test. Fasting for about 3 hours after the liver puncture is necessary because the liver is the main digestive organ of the body, and eating immediately after the puncture may cause bile secretion, which is not conducive to the repair of the puncture site. It is recommended that patients who need to undergo liver puncture should strictly follow the doctor’s instructions to make good preparations before the operation, and pay attention to sufficient rest the night before and do not stay up late. Consult your physician for advice.
