I'm new to the board, so here is my story...I've been struggling with acid reflux since Aug 2011 and my doctor was running out of treatment options so he ordered a CT. The CT showed Sclerosing Mesenteritis and also found out that I had slow gastric emptying aka Gastroparesis. Just heard yesterday that I have igG4 labs that are elevated to 163. I have suspected that I may have acquired H Pylori in 2011 but I have been tested 3 times and they were all negative. I'm also having MRI about every six months to monitor the condition and check for lymphoma, etc, so far so good. Anyone have elevated igG4 levels or share similar combination of diagnosis?
