Thank you for the information. I had heard the terms functional medicine and integrative medicine but never looked into them. I am currently satisfied with conventional medicine in treating my lung issues but conventional medicine has nothing to help my digestive problems. I know the cause of my problems is the surgery I had 5 years ago for colon cancer and the removal of the valve between the small and large bowels. Basically it is a bacterial overgrowth problem. I have met with a dietician and have tried the one antibiotic (3x) that sometimes helps but I am stuck on a white rice and toast diet and even then have debilitating cramps.
