I have severe acid reflux daily. is there a long term risk associated with this? i had an egd 4 years ago which was revealed mild gastritis.worse now?

Yes: Peptic ulcer, perforated peptic ulcer, barrett's esophagus, esophageal cancer.

Barretts to Cancer: In very serious cases, untreated GERD (and subsequent Barrett's esophagus) can lead to cancer of the esophagus . The main risk factors are smoking, drinking alcohol, poor diet, and chronic reflux disease ... But if you have a hiatal hernia, acid can move up into your esophagus and cause symptoms. The risk was proportionate to how long and how often these drugs, PPI are being taken.
