Hi.. Welcome to HEALTHCARE MAGIC.. I have gone through your query and can understand your concerns.. As per your complain hyperacidity is a condition in which there is excess formation of acid in stomach and it leads to burning sensation in stomach and chest along with belching and discomfort.. At time acid can reflux in throat and mouth causing sore throat and bitter taste in mouth.. Certain foods that are seen to common cause hyperacidity are spicy and heavy meals, frizzy drinks, chocolates, onion and garlic, citrus foods and fruits, tea and coffee, alcohol etc.. I would suggest yo to start taking Proton Pump Inhibitors like Omeprazole or Pantoprazole, antacids like Milk of Magnesia can be taken half an hour before meals.. You should take more of probiotics like Yoghurt in diet.. Drink plenty of water.. You should avoid large meals and take small frequent meals.. You should take walk after meals.. Sleep with head slightly raised as compared to feet. You should do regular moderate workout.. Avoid stress.. Hope this information helps.. Thanks and regards. Dr.Honey Nandwani Arora.
