Hi, thanks for the query.
Hiatus hernia usually don't produces any problems so avoid this, since your's
colonoscopy report is also normal, that a good thing.
Stomach fullness,dizziness ,abdominal distension, slight loss of appetite gases as all there are related to stomach problem.
In your case it seems that there is
chronic gastritis as fried food , spice food, anxiety, all are behind this disease.
Sore throat and cold not related to stomach problem but if you are taking medicines for these things than gastritis may develops due to the side effects of drugs.
First of all shun the anxiety and take bland food.
For long terms you can take
rebamipide 100 mg but after the consultation of doctor. You will be right.
Good luck. Dr. HET
