Symptoms of Pancreatitis in Children
Acute pancreatitis usually begins with pain in the upper abdomen that may last for a few days. The pain may be severe and may become constant - it may be just in the abdomen, or it may reach to the back and other areas. It may be sudden and intense or begin as a mild pain that gets worse when food is eaten. Someone with acute pancreatitis often looks and feels very sick. Other symptoms may include:

Swollen and tender abdomen
Nausea
Vomiting
Fever
Rapid pulse

Severe cases may cause dehydration and low blood pressure. The heart, lungs or kidneys may fail. If bleeding occurs in the pancreas, shock and sometimes even death follow.
