Diet is supposed to help many things.

Have you asked your physician for a consult to see a registered dietician?

Call the office and tell them what you want: a consult. That way you get lots of good diet ideas and your insurance pays for it perhaps.

What foods mess with your IBS?

Agree with Slarson, request a consultation with RD focusing on the IBS.
Nutrition and IBS alone may involve multiple visits to work thru optimal foods for you.
Your nephrologist should have advised of foods,nutrients and salts to avoid or seek out - if not I'd ask the nephrologist if anything applies to you.
You can mention the fibromyalgia to the dietitian, however I believe much is known regarding IBS and nutrients, and less about fibromyalgia/nutrients.
As far as written/on line reference materials, good luck, I do trust the Harvard Nutrition Source and Mayo Clinic publications.

I have to eat a lot of fiber and they want me to go gluten-free for a while and nothing spicy

I’ve gone gluten free after PMR….and have found that it’s helped a lot with general intestinal issues. Glutens probably actually been a problem for me for quite a while, but I just didn’t recognize the symptoms. Also, my doctor said “gluten free does not mean “a little bit of gluten””.

Have you considered using Artificial Intelligence? I use ChatGPT.com and have found it very useful with regard to sorting out medical issues and many other things! If you create a user name and password, your questions and answers will be remembered and stored. I prefer this because I don’t have to repeat that I have osteoporosis and have had cancer-it knows those things and the details about the paths that have been taken. If you’re concerned about privacy, simply type it in your browser and then ask your questions. My son taught me that the more you give it the better-unlike Google where you try to net it out to a short sentence.

Of course, AI is not to replace your medical team, but when things are confusing it is quite helpful. This is one person’s opinion.

Best wishes,
Cindy

@cmdw2600, I agree. AI can be very useful when doing research. Your son is right that the more detailed your questions and follow-up questions, the more specific the responses. In fact, the way you phrase your question can lead to different responses. That’s why it is absolutely critical that you verify the information that a tool like ChatGPT gives you. Click the link icon to review the original source to see if it comes from a trusted health source.

AI generated answers can contain errors and incorrect information. Also keep in mind that any personal health information you enter, goes into ChatGPT’s database.

We have developed guidelines around the use of AI on Mayo Clinic Connect. See the section called Guidance about the use of AI. https://connect.mayoclinic.org/blog/about-connect/tab/community-guidelines/

I encourage you to read the whole section. The part I'd like to underline is that AI tools do not replace human judgment or oversight. Any text, image or video generated by AI should be viewed as a starting point, not verified factual information. It may contain inaccuracies, biases and other problems. Always, fact check and review for accuracy, relevance, and unbiased balance.

Like you said, @cmdw2600, it doesn’t replace the medical team but be a good starting point.

I had a phone conversation with my physician this morning and got a referral to a nutritionist so keep your fingers crossed

That is great! Wish you the best!
