I am so sorry to hear you are going through this. I know how you feel my daughter was diagnosed at 15months she was having 15 to 20 bloody bowel movements a day. She had numerous stool samples done and they never found any bacteria/ parastite that showed up on normal stool testing.
After years of suffering she was given an antibiotic , that completing change her UC. Her whole colon was inflamed , and she was facing surgery. NOW she is living life like a normal 13 year old with normal stools everyday.
Her doctors now admit to me that she had a parasite/ bacteria in her colon that the "normal " stool testing did not find. They cannot test for all bacteria and parasites it is just impossible.
I am just trying to help , I was in the same place you are, and I know the saddness you feel. Please stay strong. Also I would suggest taking her to an immunoligist for further testing. 70% of the immune system is in the colon. We took our daughter to one and he was the one that searched for the answer to what was going out with her body.
I would also look into Fecal Transplant, some doctors are doing it now and find that some causes of Uc is the imbalance of bacteria in the colon . Whether it is from parasites, yeast, or bacteria. Sometimes a large amount of good bacteria can over take the bad and let the colon begin to heal.
Here is our story I made a letter that you can give to your Gi , if you consider antibiotics. Flagyl, Cipro, are the two most common ones that they try on UC and Chrons.
Please email me if you need anything
