Hi i was diagnosed with small sliding hiatus hernia. no reflux symptoms at all. wondering if this can enlarge in future and cause me probs? 23yo male

Not to worry: Sliding hiatal hernias are very common and often cause no problems. If you should ever develop symptoms of reflux which is also a common disorder affecting nearly everyone sometimes, at least temporarily, you can always treat it with one of many medicines that are available. Meanwhile, not to worry.

Maybe : a small HH can increase overtime. While many to most maybe asymptomatic, many present with mild reflux causing "heartburn". If this becomes chronic or uncomfortable see your Dr. for medical treatment. Please do not try to treat with over the counter substances before talking to your Dr. as there may be more serious problems than were anticipated.
