Which term refers to inflammation of the pancreas?

The term that refers to inflammation of the pancreas is pancreatitis. This medical condition occurs when the pancreas becomes inflamed, which can be due to a variety of factors, including gallstones, chronic and excessive alcohol consumption, certain medications, and other underlying health issues. In pancreatitis, the enzymes produced by the pancreas start attacking the organ itself, leading to a range of symptoms such as abdominal pain, nausea, vomiting, and digestive issues.

In contrast, other choices represent different medical conditions: periodontal disease pertains to the inflammation of the gums and supporting structures of the teeth, a hernia involves an organ pushing through an abnormal opening, and ileus refers to a temporary cessation of bowel motility. Thus, pancreatitis specifically describes the inflammation process occurring within the pancreas, making it the correct term in this context.
