Hi Foster...you will likely hear a few times that you should find a new GI. It sounds like you are not entirely comfortable with yours and I feel it is very important to have a good "working relationship" with your GI. I had one with a bad bedside manner and it did not help in taking care of myself.
That being said...I can't really say what is a mild flare for you. But, losing weight would be more than a mild flare for me (depending on how much and how long this has been going on). From the tone of your post and my instinct alone, I would say it's time to talk about
all of these issues with your GI. I say that...knowing that I usually wait too long to see my GI...so take me with a grain of salt
I don't know what meds you are on, how regularly you are seeing your doc, and what type of Crohns symptoms are usual for you. Just the things you describe would make me at least start planning a visit.
Take Care
