Hello, Thank you for your question. I read your problem and I had understand it. Your coughing associated with excessive saliva and heart burn are related to acid reflux. Acid reflux is when the acid that is normally in your stomach back up into the esophagus. The esophagus is the tube that carries food from your mouth to your stomach. When acid reflux causes bothersome symptoms or damage, we called it gastroesophageal reflux desease or GERD. The most common symptoms are: Heart burn-which is a burning feeling in the chest, regurgitation-which is when acid and undigested food flow back into your throat or mouth. Other symptoms include stomach or chest pain, trouble swallowing, having a raspy voice or a sore throat, unexplained cough, nausea or vomiting. You can do on your own to make you feel better if you lose weight(if you overweight), raise the head of your bed by 6 to 8 inches- you can do this by putting blocks of wood or rubber under 2 legs of the bed or a foam wedge under the mattress. Avoid foods that make your symptoms worse- for some people these include coffee, chocolate, alcohol, peppermint, and fatty foods. Stop smoking, if you smoke. Avoid late meals-lying down with full stomach can make reflux worse. Try to plan meals for at least 2 to 3 hours before bedtime. Avoid tigh clothing- some people feel better if they wear comfortable clothing that does not squeeze the stomach area. There are a few main types of medicines that can help with the symptoms of acid reflux. The most common are antacids, histamine blockers, and proton pump inhibitors. All these medicines work by reducing or blocking stomach acid. But they each do that in a different way. Sometimes, medicines cost less if you get them with a doctor s prescription. other time, non-prescription medicines cost less. If you are worried about cost, ask your pharmacist about ways to pay less for your medicines. Some people can manage their acid reflux on their own by changing their habits or taking non-prescription medicines. but you chould see a doctor if: Your symptoms are severe or last a long time, you cannot seem to control your symptoms, you have had symptoms for many years. If you have trouble in swallowing, or feel as though food gets stuck on the way down, lose weight when you are not trying too, have continue chest pain, choke when you eat, vomit with blood or have bowel movements that are red, black, or look like tar, you aspirate the acid into your lung and make you sever shortness of breath, you should see your doctor right away. Hope I have answered your query. Let me know if I can assist you further. Best regards, Dr. Heang Chan Raksmey, General and Family Physician.
