Heather Van Vorous says somewhere on her website that gastrocolic reflex occurs in proportion to the calorific value of a meal. This is one of the rationales for avoiding fat in her diet.Is there any science behind this claim?Experience tells me that it seems to be the amount/volume of food, rather than the calories, that causes trouble. For instance, a few crackers and some fatty cheese will bother me less than a serve of vehetables and several slices of bread, although they might have roughly the same calories.

Do you see where she says that exactly? On the page, ../diet/trigger1.asp,[/URL] I don't see it.Anyway, it's not the calories per se but specifically the type of nutrient. So she does have it right that fat (and amount of it) is the major trigger although the stuff about spasms and violent contractions is her ostenatious writing, not reality. There can be increased phasic activity in the colon and for example, spontaneous high amplitude phasic contractions that lead to diarrhea but I don't buy any of her hyperbole (eg. violent contractions, spasms) and the pain is something separate and not directly related. (The underlying mechansim may be the same, but contractions of the gut shouldn't ordinarily cause pain regardless of how frequently or intense they are.)The fact that volume per se bothers you suggests that you have a problem with gastric accommodation.

Ah yes, you're right...I think it actually was not on the website but was a response to a question which she posted on her "ask the specialist" board, and now I can't find it.I have been diagnosed with "a motility problem" in my stomach by my GI, although I'm not sure how he could tell this. A gastric emptying test was not performed, only endoscopy. Nonetheless, it accords with my experience. I have always felt better eating little amounts and will easily vomit and burp a lot if I overeat. I'm not sure how useful Heather's diet is to me as soluble fibre seems to trouble my upper GI - makes sense since its the "swelling" fibre. But I have IBS C as well so its a bit of a dillemma. The fibre even seems to hurt my bowels, and that's even after the "adjustment" period. I'll do ok with it for a few days, and then one day, after taking the fibre supplements the day before, I will just have pain right in the middle of my stomach which goes on ALL DAY. I am actually not sure if this pain comes from my stomach or the higher areas of the bowel. This particular symptom only happens when I try and take fibre supplements or eat a lot of fibre foods in one day. It is indeed like the volume hurts me. I have gone back to my old diet, which is basically little amounts of whatever I feel like eating. Historically that has given me the least trouble. I know it isn't great for my C but I'm thinking that fibre is really not the answer for me either.

If you have gastric issues that deal with volume the calorie density of the meal may not be the main issue for you.But it does seem to be a common issue in IBSers based on how many people have issues with high fat meals.I assume that the stomach has some mechanism for judging the fattiness of the meal because usually bile is released in proportion to the fat (or so I thought) and something has to get that information passed around to the rest of the GI tract).There may be people who are more volume issued than calorie density issued, but the fat causes problems for IBSers is an extremely common issue, so one that most people trying to write for the "average" IBSer would need to address.As always "your mileage may vary" and if you have additional problems going on that may alter what is the trigger for you.K.
