As the alginate mixture expands in the stomach, it mops up excess acid and forms a pH-neutral barrier that reduces reflux episodes.
Additionally, she postulated that smoking may be "associated with an increased number of reflux episodes and that nicotine may reduce lower esophageal sphincter pressure, which would con tribute to excess acid/bile exposure that may consequently increase neoplastic progression risk in BE.
