Indigestion is relatively common in clinical practice. Patients can undergo several diagnostic tests to rule out other causes of indigestion. These tests include gastroscopy, complete blood count, liver function tests, Helicobacter pylori testing, and abdominal ultrasound. Generally, if these tests show no issues, especially if the patient's symptoms are persistent and not accompanied by any alarming signs such as fever, bloody stools, vomiting blood, decreased appetite, or weight loss, indigestion is usually considered. In terms of treatment, symptomatic treatment is emphasized. Typically, medications that protect the stomach, improve gastrointestinal motility, and aid digestion can be used and generally provide some degree of control. Of course, this is under the assumption that other causes of abdominal discomfort, such as ulcers, inflammation, or even tumors, have been ruled out. (Please use medication under the guidance of a doctor.)
