I have had nausea quite frequently. Two years ago, had an EGD which showed some inflammation. Gallbladder studies were normal, ejection fraction was 90%. Took samples of Prilosec for a month. Nausea has continued and diarrhea started this summer. Just yesterday, had EGD/colonoscopy. Colon was normal. EGD again showed inflammation. I see the Dr. next week for followup but would like to find out what I can beforehand so I can go to him with questions. At the hospital, he did mention irritable bowel syndrome could be one problem. I'm concerned that maybe he's still looking at gallbladder trouble. I've read that a normal ejection fraction is from 14 to 75%. Mine was 90% two years ago, but Dr. said scan was normal. I sometimes do have pain behind right rib area, sometimes feels as if a lump is behind the ribs. I will sometimes feel soreness around to back and right shoulder will be sore but I've always attributed that to muscles. Fatty foods do not cause problems. Symptoms seem to be brought on more by food, just not a particular food. Do these symptoms resemble IBS more or GB? Thank you.
