2 year ago i developed acute pancreatitis with necrosis and fluid sacs following an ercp. i feel ill and my immune system is low, is this related?

Possibly: The condition that led to the ERCP may be responsible for your on- going symptoms as well. Cadmium is stored in the pancreas and would be released with inflammation. It can cause stress and inflammation and has psycho-neuro-endo-immuno toxic effects. It lowers 25-oh vit d and can increase cr-protein.

Ercp pancreatitis: This is quite common. You may have a pseudocyst of the pancreas. You should get evaluated fully. Also any chronic low grade pancreatitis will affect your general well being.
