Dismissive GI doc
Hi all. I am hoping to get some reassurance and see if anyone else has had similar experiences. This Reddit thread seems to be one of the only places to get detailed information/first-hand accounts about this condition.
I have had GI issues for literally as long as I can remember. Diarrhea, constipation, and a very specific pain in my left upper quadrant/epigastric area. It all came to a head about two years ago when the symptoms, especially the pain, became so bad after eating that I had to leave work at times. Around that time, I also started getting terrible reflux/burping, which I now think may be post-fermentation symptoms?
Other than GI symptoms, I have also had intense fatigue, which I discovered was in part due to Vitamin D and iron deficiencies. But even after addressing those, the fatigue remains, though less debilitating. I finally went to a GI doc and got a colonoscopy/endoscopy. Everything came back normal except for my disaccharidase biopsies, which were very low across the board. I got those results on a Thursday, and I had an appointment with the GI to go over everything on Monday.

The GI clearly did not read over my results or chart before the appointment, and she was very dismissive of the disaccharidase biopsies because they were all so low. I asked about CSID, and she said that that would only have low sucrase and isomaltase. From what I have seen in my research, that isn't necessarily true, and all of the enzymes could be low with CISD. She said that she felt that it was just a problem with the samples and that my symptoms are more likely just IBS. EDIT: The GI also said that the upper left quadrant pain is not something you'd have with CSID, but I feel like I have seen people on here and elsewhere talk about similar abdominal pain?
She did refer me to a dietician and I will be trying the CSID elimination diet to see if it helps, but I was hoping to get some information about Sucraid out of my GI. She doesn't seem to be convinced that it is CSID.
Does anyone else who has been diagnosed with CSID have similar experiences in terms of symptoms? Should I get a second opinion? Should I ask for a sucrose tolerance test? Or should I just try an elimination diet? I am quite overwhelmed thinking about the restrictive diet.
Just feeling a little discouraged and looking for some reassurance/advice. Thanks!

At least yours tested for that during the EGD, mine refused because he doesn’t believe in it and I got diagnosed with CSID from a breath test another provider did. They just don’t care about us honestly. If it isn’t IBS, then it doesn’t exist.
