Hello After reading your query I recommend these measures . Loosing weight , flat stomach don t help in hyper acidity . 2nd question is about complete cure ?? These measures may be useful in such type of conditions. Try raising the head of your bed about 4 inches with blocks. It might also help to avoid drinking or eating for 2-3 hours before you lie down. To help control stomach acid one should not drink ,drinks with caffeine in them or eat chocolates or greasy or fatty foods or pizza, burger . Whenever such symptoms feel you may need pantaprazole-d once or twice in a day . 2nd reason of such symptoms like gas formation , headache due to hyper acidity may be due to overeating so be careful . 3rd reason for such symptoms is tension or anxiety , so also take care. When such patient visit I prescribe them to take rabeprazole+itopride two times in day till complete cure. Since these are prescription medicine so consult your physician and get his opinion. Good luck.
