I have been suffering with gerd, stomach pain, change of bowel habit and just about any other gastrointestinal problem you could think of for almost 2 months. I was placed on Prevacid and Sulcrofanate (sp?) and that didn't improve the symptoms much so I had an endoscopy which showed nothing. The dr. told me to double up on the Prevacid and see him in a month. In the meantime, went to gynecologist and he suggested a gluten free diet. Said I had classic gluten sensitivity symptoms. Soooo, I have been on the diet for approximately 3 weeks and my symptoms improved greatly. Everything but the heartburn all but disappeared and that was greatly improved. All of a sudden today my heartburn came back full force and am having spasms of the esophagus. Is this normal? How long can I expect to be on the gluten free diet before I see consistent and sustained improvement?
