I had one develop starting in middle school. Hereditary component for me as my dad has one as well. Anyhow, had a food impacting during basic training, they had to do an endoscopy to clear it out. Finally got it taken care of a couple years later with another endoscopy where they actually fixed the hernia. I was on ranitidine a couple months pre-op then a couple years after. No issues since, as long as I don’t eat like a pig before bed, and generally maintain a healthy diet, I don’t get any reflux.
