Gastroscopy is usually required when heartburn and heartburn are present. Gastroscopy helps clarify whether the patient’s digestive tract is damaged, and combined with biopsy can clarify the presence of peptic ulcers and tumors, which helps doctors further diagnose the disease. However, some patients are not suitable for gastroscopy due to problems such as hypertension, and may consider X-ray barium angiography instead of the test.
