GI tells me now to try to SAVE my colon

Your location seems to be the problem. If you were near an academic IBD center, such as Mt. Sinai/CUNY in NYC, University of Chicago Medical School, University of California at San Francisco Dept. of Medicine, etc., you could find an IBD specialist to work with you at fine-tuning the meds your condition warrants. It sounds like the gastro you've been consulting is very egocentric, which no doubt impacts on the care/attention he gives to your case. He might also be unsympathetic to female patients. (I found in my early days pursuing treatment for my then still-undiagnosed gastrointestinal troubles that male doctors tended to think "It's all in your head, lady!" They wanted to prescribe Valium for everything.) Maybe your present gastro is a holdover from that era. It sounds to me like you have a spunky personality, you're still very young but have family responsibilities, & any decent, caring physician should be trying his/her best to help you overcome your particular form of IBD! Can your rheumatologist advise on getting a gastro consultation elsewhere-- the doctor who is getting you Humira? / Old Hat (nearly 30 yrs with left-sided UC ... [etc.])
