Gastritis is a common gastrointestinal disease with a variety of symptoms, including abdominal pain, bloating, nausea, vomiting, and hiccups. Sometimes, patients may feel full quickly, such as feeling bloated, abdominal pain, and burping after eating, so the symptoms are generally not specific. If treatment is necessary, an initial choice could be a gastroscopy. If no issues are found during the gastroscopy, symptomatic treatment could be provided. However, if symptoms extend beyond gastrointestinal issues like abdominal pain, bloating, nausea, and vomiting, and include anemia, fever, noticeable weight loss, and wasting, it is especially advised for elderly individuals to visit the hospital for further examinations including gastroscopy to rule out diseases such as gastric ulcers.
