After pancreatitis is painless, you can eat on the same day or the next day. Because there is also reference to the recovery of other clinical symptoms, such as abdominal distension, nausea, vomiting and fever should disappear completely. In addition, the indicator of serum amylase should also be referred to, and its the most critical indicator. If the serum amylase has returned to normal on the same day of recheck, the diet can be opened on the same day. If the abnormality still exists, the serum amylase can be rechecked the next day and the diet can be opened only when the blood amylase is back to normal. After opening the diet, patients need to pay attention to start with an oil-free, semi-liquid diet and gradually transition to a less oily, semi-liquid diet.
