Hi. Thanks for your query. Noted the history and understood your concerns. Starting of stomach pains an eating anything, feeling like acid is burning through the front indicate that there may be acidity related problem like Gastritis, ulcer or so. Hence I would advise you the following as Omeprazole is not helpful: Upper GI Endoscopy to have the most proper diagnosis. H. pylori test. Tests of stool: Routine and occult blood. Tests of blood. Clinical evaluation and examination by a Gastroenterologist. Barium swallow and follow-through. These will give us the most probable diagnosis and gives a plan of proper management. Continue Omeprazole. Antacid every three hourly. Soft bland diet and small frequent meals. Avoidance of stress and anxiety is the mainstay in most of the cases. Avoid all the foods and beverages that instigate or enhance the problems to get better.
