A simplified approach to the evaluation of the patient with gas-related symptoms. aIndicated in the presence of alarm features: Age > 50 years, upper GI malignancy in a first-degree relative, weight loss, GI bleeding, or iron deficiency anemia, dysphagia, odynophagia, persistent vomiting, abnormal imaging suggesting organic disease (American Society for Gastrointestinal Endoscopy). bConsider EGD (+/− gastric biopsies) and/or gastric emptying test to rule-out an organic etiology, in certain patients. EGD = esophagogastroduodenoscopy; HbA1c = glycosylated hemoglobin; IBS = irritable bowel syndrome; IBS-C = irritable bowel syndrome–constipation; SBO = small bowel obstruction; SIBO = small intestine bacterial overgrowth; TSH = thyroid-stimulating hormone.
