Well good to know that Quest actually does the stool test. I just gotta get them to admit it. lol and maybe find a new gastro doc that is willing to do test and not guess. I really hate taking meds but if i have to I have to but lets find out first with a test is my philosophy and she wasn't willing to even do that.
I know Mayo also does a random sample (one stool collection) fecal test instead of the 48 hr one, but it is only done at Mayo as they are the inventor of it and it only came available thru them very recently I understand.
A. year ago i had a gi map and it did't show any steatorrhea. Also my pancreatic enzymes were normal. and the test of intestinal inflammation and my colonoscopy all came back just fine. No hpylori or sibo or parasites.
So am working on increasing fiber to get to 20-30 grams and reducing fat grams to 50 and below. Seems everything i've researched these are two things that really affect diarrhead/bam/ibs. But these last couple days I can officially say sugar is a big trigger for me, and that's a hard one for me to reduce i'm such a sugaraholic!
At this point to get the 48 hr test, i'd be happy to drive 3-4 hrs to get to the Rochester Mayo.
Good luck on your GI journey. It is one of high self advocacy for sure from all the stories I read on many forums.
My symptoms and journey are very similar to mine although I was diagnosed with bile acid malabsorption, particularly because a urine-type secretion was appearing in my bowel movements. My fat absorption stool tests were normal. Pancreatic insufficiency was also ruled out. What caught my attention was that you mentioned that sugar is a big trigger for you. It just so happens that I have the very same problem. I am going to be asking my PCP to test me for ASID or acquired sucrase and isomaltase deficiency syndrome. I honestly believe that it's exactly what I'm fighting. These enzymes required for digestion are made in the small intestine. I believe this is the big mystery I've been fighting. I'm going to work on my gut as I believe I suffer from a Leaky Gut and that's what's causing my food intolerances and sensitivities including what I just mentioned. Also, it can masquerade as IBS and SIBO and fat malabsorption. Hope this helps. Good luck to you on your journey!
