As you've know, the stomach area is often called "the second brain", and the intestinal area could be called "the third brain" because of how these areas react to various stimuli. Some people have very strong connections between these areas, while others don't seem to have similar reactions. There is a lot of information out there dealing with this in books and on the Internet. Also, counseling can often help an individual deal with this issue. There is not a one-size-fits-all solution, but one has to investigate what works for him/her, depending upon symptoms. A good diet and proper exercise always is beneficial. Sometimes doctors prescribe Xanax for those times when anxiety is involved.
