Barrett’s esophagus is typically caused by reflux, which can be asymptomatic. It is considered a precancerous condition, I think 5% of Barrett’s patients go on to develop esophageal cancer (notoriously difficult to treat, a bad cancer to have). So it is quite serious.

Other risk factors include being male (can’t change that risk factor), and obesity. So if you’re overweight you could seek the help of a dietitian or trainer or physical therapist to help restore your ideal body weight.

You are on PPI therapy but given the ulcer (I realize you were h. Pylori positive) and ongoing esophageal pain, it is reasonable to assume (Imho) that reflux is ongoing. This will worsen your Barrett’s. Have you been on a GERD diet? You can put a 4x4 piece of wood under the head of your bed to let gravity help move stomach contents into your small intestine. Have u quit alcohol and tobacco? Fundiplication is an option but I don’t have enough information to advise for or against it.

There are quite a few options for refractory GERD. here are just a few to discuss with your doctor

Adding a H2 blocker such as Pepcid at night.

Testing for gastroparesis, where your stomach doesn’t properly pump its contents to the small intestine. There are meds to treat this.

Meds that keep the sphincter at the bottom of your esophagus from relaxation, thus keeping stomach contents in the stomach

I hope this helps
