How long after a eating a trigger food...

[Nonny]

If you eat a food that triggers cramping, diarrhea, etc., how long until the symptoms start?

I've decided that I should start paying attention to what triggers me having to run to the bathroom, and I've been in denial for a long time, but I'm pretty sure some topping on one of my favorite pizzas is going it to me.    I'm pretty sure it's not cheese/dairy, because I drink milk and ate cheese regularly without problems, but I can't ignore the fact that I always get cramps soon after eating the pizza. 

Also, any suggestions about how to best track food/ingredients would be welcome.  I'm horrible about writing down what I eat (I did it several years ago to lose a bunch of weight, got super unhealthy obsessed with it and stopped and haven't been able to start back up again).

Also, I haven't done a formal intro, but I have what I consider kind of a sketchy diagnosis of IBS.  I had/have pain in my upper right abdomen that they can't find any known cause for (I've had 3 upper endoscopies, 2 ultrasounds, colonoscopy, some other gallbladder study, a small bowel follow through, a breath test, and some other tests I'm forgetting).  I'm currently treated with a low dose of amytriptaline, which has my pain mostly under control, but I still have "random" bouts of massive cramping and diarrhea.  Definitely don't have celiac (been biopsied).

I am not sure mine was food related as much as yours sounds, but usually if I ate something that was not reacting well, I usually felt it fairly quickly... within a half hour of eating it.

I use MyFitnessPal for tracking food, it works pretty well since it does have a lot of different restaurant, grocery stores, and brand name items in there, plus you can build your own "entrees" with foods you frequently eat if they aren't already in there.

Welcome, sorry to hear you have been having issues. How long have you been dealing with the pain? That is a lot of testing, I sure hope they can figure something else out for diagnosing the problem.

My problem with food seems to kind of be sporadic, which is why I think I need to track. I was certain my problem was chocolate, but after cutting it out I still had problems, so I ate some again and was fine.

This has been going for I guess about 2 years now? I've lost track, because honestly my first GI was all about test after test after test with nothing conclusive (I did get a positive breath test and got put on antibiotics or something for it, but I was only OK for a month or so after). My new GI doesn't think I actually have a GI problem at all and thinks my pain is actually nerve pain, and that's why he put me on the amytriptaline.

It generally presents like gallbladder pain though (and I can have lots of pain without having other stomach issues). I actually was scanned once in college and once or twice for gallstones prior to the pain becoming chronic.

I do have a gallbladder and I do take probiotics.

My pain is on my right, about midway between my belly button and my side. The weirdest part is that I tend to have that pain even without any other GI symptoms.

I resisted these meds for about 1.5 years before giving in after having every test under the book and multiple opinions and no answers. I went on the meds, the pain got better, and then I stopped talking to the GIs because they were taking up too much of my time with expensive invasive tests. I need to go back to my second opinion though, because my pain is creeping back up, and my cramping/diarrhea issues never really went away (but that I can deal with, because it usually only lasts a couple of hours and then I'm OK). It's the pain that was killing me.

It depends where it effects me. Vodka and MSG are immediate, and they effect my stomach. Foods that give me gas, diarrhea or constipated me (wheat, dairy) usually take 12-24 hours.

There are very few foods that bother me right away. I have Crohn's and it isn't food triggered. When first diagnosed, I religiously kept a food diary while doing an elimination diet and added things back in. I still keep a food diary since it is helpful. I use the Fitbit website to track my food, but My Fitness Pal looks like it tracks more nutritional info.
I know my h has a mold allergy and is sensitive to yeast. Maybe there is a connection with the pizza?
