Which treatments for barretts esophagus are most cost-effective?

Antacids: Barrett's esophagus is the result of gastric acid and enzymes damaging the lining of the esophagus. Overtime, it can cause cancer. Treatment with antacid may provide relief, but you should consult a GI doctor for long term care and follow-up.

Antacids, but...: The most recent reviews i've seen indicate that there's no clearly effective treatment for barrett's itself, though the most cost-effective ways to manage the reflux that often causes it are antacids / anti-acid medicines and propping up the head of your bed on cinder blocks. Barrett's is common and your physician knows whether & how to follow you for pre-cancer, for which you get added treatment.
