Hello dear and welcome. Thank you for your query. Let me start with the reflux you are experiencing. This could be a condition called Gastro-esopohageal reflux disease (GERD). This is a pathological reflux of acid from the stomach into the oesophagus (food pipe) which would in normal be prevented by a spincter (a kind of closing, that prevents food and liquids that reach the stomach to come back into the food pipe and in turn the mouth. This happens due to the damage of that particular sphincter, called the upper esophageal sphincter. The most common causes of this condition are: Smoking Obesity Pregnancy Surgery Other symptoms of this condition are: Heartburn (burning sensation in the chest, especially in the center of the chest) Regurgitation or reflux of food particles Upper abdominal (stomach) pain Acid or salt reflux into the mouth If your symptoms match, the best method to investigate this and confirm the diagnosis is: A 24 hour pH monitoring Endoscopy Kindly consult your doctor if you feel you could have this condition Next let me help you with all the options for treatment of smoking: 1. Councelling is considered the best option, and always the first step 2. Nicotine gums, patch (as a substitute) 3. Medications (these are said the be the best and most effective treatment for smoking) Kindly consult your family physician for treatment and follow his/her instructions I hope this information has helped you.
