I'm scheduled to have the impedance study soon and was wondering what it was like? I had the pH test a while ago and my Demeester was "normal" despite my symptoms on the day, the GI said I hadn't been off Nexium long enough - 5 days but I said I just couldn't cope with being off longer because of gerd but also stomach issues so I suggested the impedance test instead.
I found the pH test horrific, I see people often complain about the motility test because of the big tube, well for me the ph test tube was the same size! I guess they use primitive technology. Is the impedance test the same sort of tube or smaller (or bigger!?)
