I am a 55 year old Woman, diagnosed with Barretts Esophagus two years ago.

During this time I had not experienced any problems and have been taking Omerzapole (20mg,daily).At the end of June

an occasional dull started in my upper abdomen as it became more intense  I visited my GP,who suspected a problem with my Pancreas and referred me to A&E, bloods were normal and ultrasound didn't show any abnormalities.Over the past month I have lost 9KG and ab and upper back pain has intensified.I have now had three visits to A&E and because my bloods are normal been sent home with an increase to pain relief. There is concerm from the A&E about my weight loss but it isn't seen as an immediate problem.

I am concerned and would like to know if a progression of Barretts or pancreatic disease is shown on blood tests.

I shall be grateful for any input.
