I want to welcome you Hed (and yes, I stayed with your story until the end-unfortunately mine is long too). I agree with what Pepe and MikeNoLomotil had to say and the supportive words from AZMom had. I cannot imagine what you have been through with all the cancer experiences in your family. I can imagine your symptoms, however, as they are very familiar to what I was experiencing. I think it is wise to rule out the cancer or other possibilities first, and unfortunately it might take something as uncomfortable as the colonoscopy to do it. However, if you are given the right meds/amt. to put you out during the procedure, it is not bad at all. I went through a lot of testing and to no other diagnosis than IBS with my GI experience, but it had to be done. It wasn't until I went to an allergist M.D. who was experienced in doing double-blinded sublingual food/chemical testing that I got to the reason why my IBS, which was usually C type, changed to frequent soft-stooling (much like you described). My stools were rather a pale yellow-orange color too (don't know if that sounds familiar), and the cramping and rectal pain were severe. I also had the extreme bloating, gas, abdominal swelling sensation, especially after eating/drinking. I knew something was wrong, but I didn't know what. I went so far in my desperation to have a hysterectomy as they had found endometriosis. I thought that this might help if it was endo on the bowel or something, that it wouldn't continue growing/put out more estrogens making it worse. The acidophilis I was trying around the same time seemed to help. The surgery did not correct the bowel problems though, as all the symptoms came back. The post-surgical follow-up exam approximately six months later found yeast caked to my vaginal wall. I had been on amoxicillin all the while of my symptoms, which a dermatologist prescribed for adult-oncet acne. The Gyno said it had masked the usual drainage and odor one would normally have (although, I knew I felt sore down there). I took myself off the antibiotic then, and unfortunately was only prescribed a local antifungal. It took care of my vaginal yeast problem, but not the bowel infection. After a few miserable years, I finally went to the allergist I spoke about above. The allergist found I was highly allergic to molds, particularily candida, and the food additive citric acid, made from fermented sugars. He put me on an antifungal and a low sugar-no fermented/aged food/beverage diet. I cut out citric acid found in many fruity and tomato products, and coffee naturally. Within a few months, my symptoms gradually disappeared. I have been on and off the diet and med for a year and a half now, and my symptoms return when I am off. The allergist predicts that it will probably take about 3 years before I can do without it. I was on 1 tab twice wkly, and have decreased to one tab every 7 to 10 days. When I start with the extreme gas and soft-stooling, I go back on and it takes care of it within a day. I can't say that this is your problem, but if it sounds familiar and you have exhausted all other testing, it might be worth a shot. It is not well accepted by all M.D.s yet, but I think that the day will come when they begin to recognize it as one. Fungal infections elsewhere in the body may be a clue. The bottom of my foot started peeling/sloughing off dead skin, and quit when I went on the antifungal/diet treatment. You could try refrigerated enteric coated acidophilis and a low sugar diet and see if that is helpful. I wish you the best Hed in figuring out your particular problem and managing your symptoms. God bless. [This message has been edited by moldie (edited 06-13-2000).]
