Pancreatitis is a disease where the digestive enzymes in the pancreas are activated internally, causing the pancreas to digest itself. Clinically, it presents with upper abdominal pain, nausea, and vomiting. If severe, the abdominal pain can be intense. In such cases, one should register with the department of gastroenterology, as the pancreas is also an organ of the digestive system. If the hospital does not have a gastroenterology department, one could consider registering with the department of internal medicine. If the pancreatitis is severe and requires surgical or other treatments after examination by the gastroenterology department, further referral to another specialty for treatment may be necessary.
