Regurgitation occurs in RS due to increased gastric pressure achieved by subconscious contraction of the abdominal musculature wall, reversing the pressure gradient between the esophagus and the stomach. RS is mainly diagnosed clinically by the Rome Criteria with symptoms of regurgitation without retching of recently ingested food into the mouth and subsequent spitting or re-mastication. When the diagnosis is unable to be made clinically, supportive testing including fed impedance manometry can be considered. RS occurs worldwide, affecting patients of all ages, races, and genders with a prevalence of 3.1\u20135.8%. There is significant overlap with RS and disorders of a gut\u2013brain interaction and upright gastroesophageal reflux driven by aerophagia and supragastric belching. There is also an association with mood disorder, fibromyalgia, and eating disorders. RS may be misdiagnosed as a variety of other syndromes including gastroesophageal reflux disease, gastroparesis, achalasia, and bulimia nervosa. Once RS is diagnosed, the mainstay of treatment is diaphragmatic breathing to lower the intragastric pressure and increase the lower esophageal pressure. Diaphragmatic breathing can be supported with biofeedback and cognitive behavioral therapy as well as medication options for more refractory cases. Response to therapy overtime and changes in symptoms overtime can now be tracked with a validated questionnaire.<\/jats:p>","DOI":"10.1093\/dote\/doae041","type":"journal-article","created":{"date-parts":[[2024,5,14]],"date-time":"2024-05-14T06:36:24Z","timestamp":1715668584000},"source":"Crossref","is-referenced-by-count":3,"title":["Current
