Marathon pancreatitis: is the etiology repetitive trauma?

Abdominal pain frequently occurs after long-distance running. The cause of the pain may be due to dehydration, diaphragmatic ischemia, muscular spasm, or myonecrosis. However, data regarding the frequency of these purported causes are currently lacking. Pancreatitis can also occur after long-distance running, but few cases have been reported, and the etiology is controversial. We report a case of pancreatitis in a thin, muscular marathon runner. We suggest the etiology in this case may be traumatic as the pancreas may have suffered repetitive injury against the posterior abdominal wall and spine.
