CES, Find a new doctor! Try going to an OSTEOPATH... they are more open to nutrition and a holistic approach. There are MANY trigger foods and you need to start READING labels and keeping a food diary, so that you can keep track of what sets you off. Go to the BACTERIAL OVER GROWTH TEST subject on this boad, and scroll down to one of my later postings... I detail many of my trigger foods, one is a food preservative that is in MANY different kinds of foods. Unless you start READING labels and seeing WHAT is in your food, you will never ascertain WHAT makes you have D. Everyone is different. I am lactose intollerant, sulfides cause me D too, as does chili spice, sesame seeds. These are hidden in many foods.If you suffer from C, then take calicum citrate with magnesium supplements, if you suffer from D, then look into what I am taking. Since you are a woman, this won't hurt, as women need calcium to build up our bones.I was told by a woman doctor "your D is in your mind and you can control the bowel." At the time I was 20 and I weighed 74 lb. I'd had uncontrollable D for 2 years. I'd begged all the doctors to do allergy tests, but they all said: "It's in your head." Nine doctors told me this. That was 27 years ago. Eventually, I discovered the condition of lactose intolerance. As soon as I cut milk sugar out of my diet, the D stopped and I gained 15 lb. in a few months (back to my "normal" skinny weight). Through weigh-training I gained 21 lb. more over a number of years. IBS, D, C, are NOT in your head. And, BTW, I was not, and AM NOT, a "nervous", high-strung person. Please do NOT allow these doctors to blame you for something they're incompentent to diagnose. YOU NEED TO DIAGNOSE WHAT IS SETTING OFF YOUR SYMTOMS YOURSELF. Good luck.
