eMedicine - Gastroesophageal Reflux Disease : Article by P Marco Fisichella
If you are unintentionally losing weight, have difficulty swallowing solid food, any blood in your bowel movement, you need to be seen by a physician asap.
Your remaining stomach volume may be shrinking due to scarring and this is causing a gastric outlet obstuction.
In my opinion, you need a Esophagogastroduodenoscopy [ upper endoscopy ].
Are you taking any medications to reduce stomach acid? [ Prilosec, nexium, zantac etc.]
