<s>[INST] Hi a cousins husband had abdominal pain and went to see his dr. They did a CT, and endoscopy. Saw pancreas was atrophied. Dr. felt had been this way for 20 years. A1c Hemoglobin level elevated to 7. Hasn t seen a specialty dr. yet. No previous problems. Not a big drinker, etc. no Nausea , no vomiting, no wt loss. he has essential tremors. Who should he see, and would an other test help see if other organs are involved. or if pancreatic ducts are blocked, etc. I m A NURSE, BUT THIS IS NOT MY AREA. [/INST] Hi.Thanks for your query.Very true, we have to confirm the diagnosis. The best ways are::MRCP and Endoscopic USG. This will confirm the diagnosis.The blood tests are not of importance in chronic cases.You have to see:Gastroenterologist and Neurologist for essential tremors.This condition appears in fatty infiltration of pancreas. It is better be  confirmed as is the blood sugar levels to be monitored. </s>
