Kind of a long writeup, but I'll give you some background:Early 40s, very fit. Main symptom: stomach pain. Can be bloated feeling (not really visible to the eyes), but it's usually either a dull ache or more of an acute, burning feeling in the stomach. Belching is fairly common, flatulence level is normal. Diarreah and constipation are rare. Stool varies in color but I think mostly normal. Generally I have pretty good, if occasionally sudden, BMs. For example, last night I had a cup of black beans with brown rice, and that took about 90 mins to through me (which is pretty unusual). Today I had half as many of the same black beans with salad, and it's been 5 hours and no problems. Yesterday I had the same brown rice with chicken, no sudden problem. So it's been a little confusing.Trigger foods seem to be:1. Certain fatty things, especially Baked goods (cookies, pan treats, etc.), donuts, pizza, frosting, some fast food burgers, fattier salad dressings. However, things like steak, ham, eggs, and peanut butter don't tend to cause issues. I eat lite mayo and it doesn't bother me, nor does the occasional frozen breaded chicken breast. I don't want to eat many of these things (other than meats and eggs) regularly anyway since they aren't nutritious, but occasionally it hits the spot.2. Certain carbs: whole wheat (including stuff like Wheaties), some types of white/brown rice, couscous, and beans (esp. kidney for some reason; black beans, less so). Potatoes and instant oatmeal do not bother me. Some white flour stuff seems to bother me, but generally if it's not a fatty item, it's not too bad. 3. Tomato products. It doesn't happen every time, or with every kind, but I don't always seem to do well with ketchup, bbq sauce, tomato sauce, etc. Pizza is usually a bad idea, so I try to limit it to once every two weeks. I'm not sure if it's the sauce or the fact that maybe I tend to eat it on fattier things like burgers. I basically have been too afraid to try spicy and peppery stuff.I drink kefir (yogurt variant) without problems, but I'm wary of milk. In the fall, I had some real pains after drinking milk that went on for days, although a few weeks ago (a few days before things took a turn for the worse) I had cereal w/skim milk for several days with no discomfort at all. Bananas bother me at times, not at other times. Things as varied as romaine lettuce, steak, ham, apples, instant oatmeal, and peanut butter don't bother me. In the fall things escalated to the point where I was waking up in the middle of the night with severe stomach pain. I thought it was an ulcer, but I didn't have one. The doctors guessed it was gastritis and put me on a PPI that I've been off and one for about 6 months (mostly on). I felt better after a week, but it may have also been that I switched to a bland diet. I've had all kinds of medical tests, including an endoscopy, and my digestive functions are normal. No signs of a hernia, ulcer, celiac, etc. I do not have GERD/reflux.Last week, I had something with tomato in it and felt that familiar burning stomach pain that seems to last all day and night (it goes after a night's sleep). I have found that Tums, Maalox, Pepto, etc. do absolutely no good when I have this pain, nor do digestive enzymes. On a lark, I bought Charcocaps and tried them, and, lo and behold, the pain went away almost completely. I couldn't believe it. Was it just gas all along? The pain did return about an hour later to a lesser degree, so it would seem like if it were gas that it would not have returned since I didn't eat anything else. I'm going to create a separate post to ask people about charcoal.Maybe I don't really know the difference between gastritis pain and gas. Sometimes I have pains that are almost like hunger pangs and so it gets hard to tell the difference. Ok, so here's the question from the title: Does this sound like IBS?
