Hi and welcome. Sorry you're feeling lousy.
Please keep in mind that I am not a doctor. But, since you asked, I think you should go with the first doctor's recommendation and start 6-MP right away. You may want to see the posts of other folks on the board who have used this med with no problems for 20+ years if you need reassurance about
it's safety and whether it works well.
It takes up to 4 months before you know if 6-MP is going to work so it's best not to delay starting it if you are having active symptoms now.
If you have progressed from a 1 to a 5 in 3.5 years how far will you have progressed in another 3.5 years? Emergency surgery due to bowel obstruction or perforation are not uncommon even with ongoing maintenance medications. The likelihood of serious complications is pretty significant and grows the longer the inflammation goes unchecked.
If you haven't been very sick so far, it can be hard to take CD seriously and understand the need for more aggressive treatment than has worked for you in the past. But it is typical for the course of the disease to worsen over time. Sometimes it gets a LOT worse with very little warning.
It's hard to interpret lab values without the corresponding normal ranges listed. These values vary from lab to lab so you can't usually make a blanket assumption about
what's a "normal" value and what's not. For example, CrP is one test that has 2 different versions that are measured in different units and have very different normal ranges.
If you'd like to post more info about
the tests you listed I'd be happy to try to help you understand the results.
Celiac disease - the gold standard for this is endoscopic biopsies. It sounds like the blood test to rule this out could not be interpreted due to a low IgA level. Thus the comment that you need a small bowel biopsy to rule it out. I'd be interested in knowing why your IgA is low and just how low it is. Did the doctor run any other IgG levels or sub-factor tests? They 'd all start with Ig + a letter of the alphabet for the main ones.
Finally, not all GI's are well-informed or have much experience treating IBD patients. If you are seeing a general GI doc and want a 2nd opinion it's a good idea to go to an IBD clinic at a major teaching hospital or center where they have a lot of experience treating IBD patients. A community GI may only see 5 or 10 IBD patients a year and just doesn't have time to keep up with the latest treatment standards. An IBD clinic doc may see 100 - 500 IBD patients a year and is most likely to provide a reliable expert 2nd opinion.
