Hello , I'm so glad that you've reached out here. My heart goes out to you and your daughter that she is dealing with, not only a fairly new diagnosis of colitis, but also a current flare up for the past three weeks. You are correct that everyone is different, however, you daughter is not alone in having the experience of a flare up causing blood in the stool. I'm sharing a link to an article that one of our advocates put together about what a flare up looks like for her, https://inflammatoryboweldisease.net/living/uc-flare-up.
Also, if you haven't already, please don't hesitate to reach out to her doctor, especially with any new or worsening symptoms. Sometimes it can be helpful (and reassuring) to check in with the doctor in charge of care and treatment.
Watching our children deal with difficult health challenges can really be heartbreaking, and I just wanted to let you know that we are here for you! Hopefully some of our community members here can also chime in and share their experiences with you as well. And, please don't hesitate to reach out here anytime. This community is here for you both! -- Warmly, Christine (Team Member)
