I realize that this is an old thread so I may not get any reply. Well anyway, I am disabled from a combination of schizoaffective bipolar disorder and the whole sleep apnea-IBS-fibromyalgia-chronic pain and fatigue-complex of symptoms.
In regard to the IBS and the sweating and faintness...I used to have attacks at work and even though the hot flash/sweating and faintness feelings were disturbing, I simply chalked them up as a reaction to all of the adrenaline pumping into my system, combined with the huge amounts of endorphins being released to combat the pain in my abdomen. Also, as soon as the pain began to abate the other symptoms would go along with it so I thought it must be the pain triggering the other reactions. Since I am no longer having such terrible IBS episodes (mostly because I am no longer able to work??) I never get the sweating/sensations of heat and faintness reactions.
When I did get the pain I could not function normally at all, I would have to go into the bathroom and park there, doubled over with pain and clutching at my stomach. This was usually followed by a loose bowel movement (not always diarrhea) and then slowly the pain/sweating sensations would subside along with the pain.
I don't know if any reference has been made to coffee drinking, but because of the sleep apnea I was having major trouble staying awake at work and was drinking quite a bit of coffee to try to stay awake. Aside from causing major heartburn/GERD symptoms, I felt certain that the coffee consumption had a lot to do with the IBS severity. Also coffee affects the insulin in the body and I know that insulin problems can cause sweating and for me a feel of overall emotional upset, sort of like being mentally nauseous.
A friend of mine told me that his doctor agrees about the coffee...saying that coffee causes problems because it comes from a bean and that beans in general are not good for IBS. Also the cruciform vegetables like broccoli and cauliflower. The reason that tea drinking does not cause the problems, even though it has caffeine in it, is because it comes from the leaf of a plant, not from a bean.
One other consideration is the use of Librax, which was prescribed for me for IBS. It has Librium in it, combined with a smooth muscle relaxer, and Librium has all kinds of mental side effects and I hear that withdrawing from it can be even worse than taking it.
I am no longer taking Librax but have asked my doctor for the Librium because of severe panic/anxiety/phobic attacks at night, during which I am afraid to go back asleep due to nightmares and fears of asphyxiating or dying in my sleep. I also have a presription for Darvocet for pain relief and I try not to take the two together because they are not mutually beneficial...I only take the Librium when I can't "talk myself out of" the panic attack or the fear becomes so bad that I can't tolerate it.
By staying away from coffee and refried beans and eliminating the stress of being sleepy at work I hardly ever have the severe IBS attacks. Recently though I have started drinking coffee again (due to being purely addicted to it) and the heartburn/GERD is returning so I am trying to talk myself into going back on tea. Plus it has good antioxidants in it and other health benefits.
One other thought though...I was having problems with profuse sweating for a while but not during an IBS episode. I had my blood sugar checked and it was high, along with my triglyceride levels. I have managed to lower my blood sugar with diet and by taking metformin. While I don't have actual diabetes, there is a thing called "metabolic syndrome" where the body still produces insulin but does not get the proper results from it. Knowing what I do now, I would always have my blood sugar checked after a severe sweating incident (I still sweat terribly right after a shower but I think that's because the skin pores get dilated during the shower). I use to get hypoglycemic spells that were very severe, but now I have apparently swung the other direction into the pre-diabetic area and I am doing my best to control my sugar intake and keep taking the metformin so I don't convert to true diabetes and have to take insulin or risk any of the terrible secondary problems that diabetes can cause (like blindness for instance).
Well that's it for my sad story (ha ha). I'm not trying to disagree with anybody or promote my way of thinking, just relating what happened to me and what has seemed to help.
P.S. Eating oatmeal really does bring down the cholesterol levels..those were high in me along with the blood sugar and triglycerides, plus the "good" cholesterol was low as well. My doctor was really suprised at how my blood sugar and cholesterol results were improved just by eating multi-grain bread and cereals in my diet and trying to avoid refined sugars as much as possible.
