Hi i've frequent severe acidity problem so did endoscopy doctor said it's small hiatus hernia acidity keep coming back is there any permanent solution?

Lot's of people...: ...have hiatal hernias. Most are sliding type & appear intermittently, requiring no intervention especially when small. However, as to your question of a permanent "fix" for GERD, there are a number of endoscopic and minimally invasive techniques that bolster the lower esophageal sphincter reflux barrier--but even these can break down over time or become complicated in some people.
