My history: I've had a celiac disease diagnosis (and actually MC diagnosis) since 2020, so I've been off gluten since then and am very aware of cross-contamination (have my own dishes/don't eat out/etc.). Doc and I thought the MC would go away after gluten stopped. I've had watery D for ages and though I saw slight improvement when eliminating gluten, it never left. I'd have undigested fruits/vegetables in my D and constant annoying gurgling. In August, I went to see a new GI since I wanted to continue to work on bettering my GI tract. I did an endoscopy/colonoscopy, which showed my small intestine villi looked healthy but there was still MC. I was doing mediocre before the colonoscopy, but afterwards my D has been ferocious.
Budesonide (9mg>6mg>3mg) for 3 months in August did not work. In December, I found Wayne's book, and eliminated dairy, soy, eggs, and most other foods and got an Enterolab A1+C1 panel (results below). Since December I hadn't been eating any of my +1 foods anyway. I've been eating mostly chicken, pork, rice, potatoes (no skin), and salt for the last 8 weeks. January I started taking D3 (safe ingredients) and magnesium spray daily. I've been preparing the meat low-histamine style as well. I had to eliminate bananas and sweet potatoes which may have been too much fiber of initiated a histamine reaction (in the case of bananas). I've noticed olive oil may bother me in greater amounts. The only change I noticed with restriction to 4 safe foods is little to no gurgling during the day and a slight decrease in D frequency. Pancreatic elastase test showed EPI but I haven't yet tried enzymes. I've been on cholestyramine (Laine's brand) for a week and a half, even ramping up to 8 packets a day the past week and have not noticed a difference. Still having watery (yellowish) D, occasionally urgent and with the need to pee.
Fecal Anti-gliadin 18 units
Fecal Anti-casein 21 Units
Fecal Anti-ovalbumin 26 Units
Fecal Anti-soy 5 Units
Mean Value 11 Antigenic Foods 7 Units
Foods to which there was no significant immunological reactivity: Corn Oat Rice Chicken Pork Almond Walnut White potato
Foods to which there was some immunological reactivity (1+): Tuna Beef Cashew
(+2): None
(+3): None
Looking for your insights/suggestions on what to try next. I still have some budesonide, so I could see if that works now that I've made dietary changes. How long does cholestyramine take to see a change?
Working hard to get better.

Thanks!
