What does gastritis mean?
Gastritis is the medical term for inflammation of the stomach lining, the layer of tissue known as the gastric mucosa. It can be acute, developing suddenly, or chronic, persisting or recurring over time. The condition may be associated with infection, including Helicobacter pylori, use of non-steroidal anti-inflammatory drugs, alcohol, smoking, autoimmune disease, or other forms of irritation. Symptoms can include abdominal pain, nausea, vomiting, and a feeling of fullness, but symptoms alone do not establish a diagnosis. Gastritis is not simply another word for indigestion: indigestion describes a range of digestive symptoms, whereas gastritis identifies an inflammatory condition affecting the stomach lining. The word is used mainly in medicine and health information, where precise diagnosis depends on clinical evaluation and sometimes tests such as an endoscopy.

Gastritis has a precise target: it is inflammation of the stomach lining, not simply an upset stomach.

Where does gastritis come from?
Gastritis was formed from the Greek word gaster, meaning “stomach,” together with the suffix -itis, a term used in medicine to denote inflammation. The Greek form had the genitive gastros, which also underlies English words such as gastric and gastroenteritis. In English, gastritis developed as a medical term in the nineteenth century, following the established use of Greek-derived anatomical and pathological terminology.
