Hi and welcome to HCM! Thanks for posting your query here. Acid reflux is due to weakening of the lower esophageal sphincter- this causes a reflux of acid produced in the stomach into the esophagus. It can be treated either by decreasing the acid secretion-like using omeprazole or pantaprazole or Rabeprazole or by neutralizing the acid- by antacids. If one drug is not acting you can change the drug and dosage and frequency with your doctors advice. For example sandoz 20mg can be replaced by Pantop 40mg with a tab twice daily may improve your symptoms. If GERD is associated with hiatal hernia the symptoms will be more disturbing. Hence an upper GI endoscopy is recommended to rule out any hernia or barrett s esophagus. If the conservative therapy fails you have an option of the surgery which is called fundoplication. Life style changes like reducing the stress, taking low fatty and low spicy foods, taking food in time and walking for atleast half an hour after meals will reduce the symptoms in GERD. Hope this is helpful to you. Thankyou.
