I should mention that I also have gastroparesis(delayed emptying of the stomach) and ibs(diarrhea) and I am fructose intollorant. I hope that helps. The testing I had done was blood work, a ct scan of the abdominals, and endoscopy. The blood work and ct scan came out great. That was my doctors words. The endoscopy was done by a GI doctor, and found alot of acid buildup and she had to stretch my hole (where the food exits) because it was very small and inflamed. The pain I have had never moved. It is always in the same place. Where the small intestine is. It is not in the stomach. And it is as though little critters are nawing at my intestines. It is horrible. I have had this same pain everyday, for 6 months. The pain dosent move around it is always in the middle of my intestines. I have extremely severe bloating from IBS but it has been alot worse since I got this. I was having alot of diarrhea to. But then I started taking the probiotic culturelle and it stoped. I hope I am taking the right one. I made a stevia candy bar the other night with just bakers chocolate unsweetened and stevia. I was in so much pain the next day I thought I was goind to die. I hope this gives you some ideas. I also drink juice out of green veggies, since I can’t eat them raw. I can’t eat much at all. I can only eat once a day right now, and I have lost over 60 pounds and I am still losing.
