<s>[INST] Hi. I have been having gallbladder symptoms. My ultrasound and blood work fine. My ejection fraction was the following: 10 min no emptying, 20 minutes, 16% and 30 min 37%. They told me I am in normal limits. I am reading that below 40% is abnormal...is this so. I have horrible back pain, constant belching, diarrhea. When I eat fat I am in a lot of pain. Now starting to get a lot of sharp pain under rib cage on right side of abdomen. Please advise. Thanks. [/INST] Hi, I have gone through your query. The values you have mentioned are something different. Ejection fraction is normally between 50% to 60%. As your doctor said that it is within normal limit then be it so. Back pain, belching and increased pain on fatty food may be due to pancreatitis, as your ultrasound reports are normal. I would suggest you to go for blood amylase. If it is raised then it will confirm pancreatitis. Mentioned symptoms are seen in Inflammatory bowel disease, so colonoscopy may be required if all investigations came out to be normal. In the meantime avoid oily, junk food and alcohol. Do consider positive feedback as a credit to my work. Let me know if you have any further questions. </s>
