I am spitting, irritation in throat have weight loss in 6 months (6 kg) & Naueaa. Sonography, Barrium X-ray, Stool Test done &shows normal. Reason?

GE Reflux. I am glad to know above tests are Normal. Try omeprazole /Ranitidine like drug. Also monitor what kind of food(solid vs Liquid; Spicy vs Dairy Etc) causing Nausea/irritability. may check for celiac disease, H. pylori gastritis. May need EGD and Esophageal Motility study if symptoms continue.
