Gastritis

Gastritis is a general term for inflammation of the gastric mucosa and is a common disease of the digestive system. It can be divided into acute and chronic types. Acute gastritis is divided into acute simple gastritis, acute erosive gastritis, acute corrosive gastritis, and acute suppurative gastritis; chronic gastritis can usually be further divided into superficial gastritis, atrophic gastritis, and hypertrophic gastritis. Acute gastritis manifests as upper abdominal discomfort, pain, anorexia, nausea, vomiting, and even bleeding. Chronic gastritis mostly has no obvious symptoms, only dyspeptic symptoms such as postprandial fullness, acid regurgitation, belching, and irregular abdominal pain. Definitive diagnosis mainly relies on gastroscopy and gastric mucosal biopsy. This disease is common in adults, and many factors can irritate the stomach, such as improper diet, viral and bacterial infections, and drug stimulation, which may trigger the disease.
