A 30 year old patient is diagnosed with pancreatitus. Pancreatitus is usually
caused by one of two factors, excessive alcohol use or gall stones
blocking the pancreatic tract. Gall stone usually do not develop
until the age of 35 (age, race, or sex are not a factor). The patient stated he had been drinking excessively for three months and tests found elevated liver enzymes. More tests found gall stones, but were inconclusive as to whether the stones were blocking the pancreatic tract. Therefore, the pancreatitus was most likely caused by excessice alcohol use.
