I am 70 and have a small barrett's segment. am now taking nexium (esomeprazole) 40 mg. i have been untreated apparently for sometime. not happy- very anxious.

Worry about Barretts: It is normal to worry. It is, in face, probably normal to be angry that this is happening. But, you are on the right treatment. Nexium (esomeprazole) is very powerful and a great tool to back this risk of esophageal cancer back a bit. It sounds like you are now connected to a good professional who will keep you monitored appropriately.
