Hi.. Welcome to HEALTHCARE MAGIC.. I have gone through your query and can understand your concerns. As per your complain it seems that you are suffering from Gastroesophageal Reflux Disease commonly known as Acid reflux and it is not necessarily due to H.pylori.. It is due to weakening of band of muscles in the lower end of oesophagus known as Lower Oesophageal Sphincter and when it does not close completely the acid from stomach can regress into the throat and mouth and cause heartburn, sore throat and bad taste in mouth.. I would suggest you to consult a Gastroenterologist and get evaluated and he can do a clinical evaluation and also advise upper G.I endoscopy to rule out the exact cause of the symptoms and treat accordingly.. In case if H.Pylori is suspected it will be investigated and treated accordingly.. As of now you can take Proton Pump inhibitor like Omeprazole, antacid like Calcium Carbonate or Milk of Magnesia before meals, take low spice diet, do short walk after meals, drink plenty of water, add more of yoghurt to diet, sleep with head slightly raised as compared to feet and recline in left lateral position. Hope this information helps.. Thanks and regards. Dr.Honey Nandwani Arora.
