Hi Nicole,   here are some links to information you might find helpful. While online sites are great resources for getting information to help you manage your health, they can not serve as a replacement for seeing your doctor.   You've been diagnosed with Barrett's esophagus, a potentially serious condition where pre-cancerous cells are present as a result of the acid wearing on the esophagus. You can read more about Barrett's here. Also there is an informative article here. As far as the gas, that can be caused by a combination of things. Anything from your diet, to the affect your medicines have on you. You can read more about gas and belching here.   Hope this helps. Stay in touch and let us know how you are doing!Vicki M
