What are the symptoms of gastritis?

The main symptoms of antral gastritis include upper abdominal fullness, dull pain, or severe pain, which may occur periodically and often worsen after eating. Patients may also experience dyspeptic symptoms such as belching, acid reflux, nausea, vomiting, loss of appetite, weight loss, diarrhea, or constipation. Some patients with antral gastritis may have no obvious symptoms or only mild tenderness in the upper abdomen. The severity and duration of antral gastritis may influence the prominence of symptoms, and long-standing cases may lead to a decline in nutritional status, resulting in signs such as anemia and weight loss. Therefore, prompt medical attention should be sought upon experiencing the aforementioned symptoms for early diagnosis and treatment.
