@kathyhg Since your nausea is extreme, you may want to have your stomach checked for mac. It can sometimes diseminate there. There are other 'comorbid' diseases that can come with mac that would affect your stomach. For example: a mutated version of CF, etc. That is yet one more reason I like going to the Mayo Clinic; they can do genetic testing. Just an FYI, Mayo does offer a genetic disease testing panel for $150.00 to screen for hidden genetic issues. You donot need to be a Mayo patient to purchase it. It can be found on the Mayo website.
