Excessive supragastric belching is rarely described in the anesthesia literature. Anesthesia planning of a 26-year-old patient with excessive supragastric belching, history of superior mesenteric artery syndrome (SMAS), and dental anxiety requires preoperative assessment. This case report outlines the anesthetic considerations and the management to facilitate comprehensive dentistry. Key anesthetic considerations include anxiolysis, aspiration risk reduction, total intravenous anesthesia (TIVA), and postoperative nausea and vomiting (PONV) prophylaxis.
