A barium meal usually detects stomach ulcers. Barium meal test, i.e. X-ray barium meal test, is a commonly used test for gastric ulcer disease in clinic. It means that the examinee takes barium sulfate prepared by professional doctors orally in an empty stomach, and observes the digestive tract under X-ray, which can then check whether he or she suffers from gastric ulcer. If gastric ulcer is confirmed, the patient should cooperate with the doctor for targeted treatment. Barium X-ray examination can also detect a variety of digestive tract diseases, such as esophageal tumors, duodenal ulcers and so on. For patients with gastric ulcers, they should under the guidance of the doctor, carry out relevant examinations for comprehensive determination, such as gastroscopy, to avoid adverse effects.
