Hi and welcome to Healthcaremagic. Thank you for your query. I am Dr. Rommstein, I understand your concerns and I will try to help you as much as I can. Your symptoms are nonspecific, but these may be suggestive of gastritis, GERD or hiatal hernia so you should do gastroscopy to evaluate it more accurately. This is caused by irritation of stomach mucosa by certain food or medications, stress and smoking. You need to avoid fried food, carbonated drinks, coffee, alcohol and spicy food. You should eat more milk products, vegetables and boiled food. Also, certain antiacid medications may be required by diagnosis should be established first. I hope I have answered you query. If you have any further questions you can contact us in every time. Kindly regards. Wish you a good health.
