Which term refers to the inflammation of the stomach lining?

The term that refers to the inflammation of the stomach lining is gastritis. This condition occurs when the protective lining of the stomach becomes inflamed, which can lead to symptoms such as abdominal pain, nausea, vomiting, and indigestion. Gastritis can be caused by various factors, including excessive alcohol consumption, chronic vomiting, stress, or the use of certain medications like nonsteroidal anti-inflammatory drugs (NSAIDs). Recognizing gastritis is important in clinical practice as it can lead to more serious gastrointestinal issues if left untreated.

In contrast, gastroenteritis refers to the inflammation of both the stomach and the intestines, usually caused by infections or irritants. Peptic ulcer disease involves the presence of open sores on the stomach lining or the upper part of the small intestine and is distinct from gastritis. Duodenitis specifically describes inflammation of the duodenum, which is the first part of the small intestine, rather than the stomach. Understanding these distinctions helps clarify the specific condition being addressed.
