Which factor is NOT a common cause of pancreatitis?

High blood pressure is not considered a common cause of pancreatitis. The condition is primarily associated with other factors that directly impact the pancreas. For instance, obstruction, often due to gallstones, can lead to inflammation of the pancreas by blocking the pancreatic duct. Alcohol consumption is another well-known cause, as excessive intake leads to direct damage to pancreatic cells and can induce acute or chronic inflammation. Post-Endoscopic Retrograde Cholangiopancreatography (ERCP) complications can also result in pancreatitis as the procedure involves manipulation of the bile and pancreatic ducts, which can irritate or damage the pancreas.

In contrast, while high blood pressure may have various complications affecting different organ systems, it does not have a direct pathological relationship with the onset of pancreatitis. Thus, it is not classified among the usual etiological factors leading to this condition.
