This is a very unprofessional mish-mash of some thoughts I have had based on some reading and research.The digestive system is extremely complex. There are many steps in the process. The digestive system is autonomous and can command this process on its own without help from the brain.The digestive process is regulated by the careful timed release of several type of hormones. They stimulate nerves which cause contraction of muscles, secretion of other hormones, and digestive fluids, etc, etc.The amounts of the hormones and their timing is extremely important to smooth, normal digestive function. A slight fluctuation in this complex rhythm leads to digestive problems.The interesting thing is many of these hormones are also apparently the hormones that regulate mood (serotonin, NK-1, etc). Again too much or too little of these chemicals can cause depression, anxiety, etc.It's a slight reach but it would seem to me that IBS and anxiety go hand in hand.While it seems it possible to have anxiety without IBS. It seems to me it is impossible to have IBS without anxiety (I'm talking chemically)So for all of us he think that all are problems are our own fault ..."no guts" and also associate their IBS with stressful situations should understand there is a complex chemical situation occuring and your IBS may not be a result of your stress. Your stress and anxiety may be the IBS. Chemically these may be the same thing.I've also read some research that states that infections (ie bacterial) can and do produce toxins which inhibit the action of these hormones. Therefore the mental and physical symptoms we experience may actual be a complex chemical reaction caused by external factors.For all those, including myself, who blame themselves for these symptoms (ie worry too much, too anxious, etc), know that IBS and anxiety may be one in the same (chemically). And although we may be able to reduce our symptoms by certain coping techniques the real problem we may beyond our total control. Those who have learned to associate mental stress and anxiety with IBS should not blame themselves. These hormones effect both.It's interesting that our biology uses these hormones for both mood and for digestive purposes.Researchers are getting closer to unraveling this complex puzzle. But I think we should try to give ourselves the benefit of the doubt. We may have no more control over IBS and anxiety then some people have on catching a cold. IBS/Anxiety is chemical. So unless anyone can prove otherwise I'll just choose the egg...and it's not my fault(just not sure of the cause...yet).
