Hi Tmos,
I agree with the previous commenters; it IS important to get a diagnosis and treatment, even for mild CD.
I can share my own experience. I have mild CD. Before diagnosis, I had 1-2 D per day without much pain. I spent about a year of not really thinking it was a big deal, but still feeling like what I was experiencing wasn't normal. After my second "accident," I bit the bullet and got a referral to a GI. A few months later, I had my diagnosis of CD (regional enteritis of the terminal ileum) and began treatment.
So even though my CD is mild, diagnosis has been beneficial in a number of ways:
1. I am receiving appropriate treatment. Even though my symptoms were limited to 1-2 D a day and occasional incontinence, getting treatment has made a huge difference! I don't have D anymore, except on occasion. I had not realized how much the D had interfered my life until I stopped having it.
2. Peace of mind. Admittedly, my diagnosis was overwhelming at first. It was a bit scary to accept that I have a chronic illness that will be with me for the rest of my life, but it sure beats not knowing! Knowledge is power; even though the future we all face is scary, at least I know what I'm up against; I know what is within my control, and what is not.
3. Support. Getting a diagnosis enabled me to reach out to this community and interact with people who understand what I am dealing with.
As already mentioned... getting treatment even when you're not flaring can help prevent future flares, and having an official diagnosis comes in handy when it comes to insurance/disability/taking time off from work (when needed).
Anyway, I hope this is helpful! I encourage you to continue to pursue a diagnosis with your doctor. If you haven't already, push to get a colonoscopy (NOT a sigmoidoscopy!). My GI doc (who is totally awesome, btw) suspected I had IBS, based on my mild symptoms, but ordered a battery of tests to rule out other things. He gave me the option of colonoscopy or sigmoidoscopy -- I chose colonoscoy (figured, if you're going in, might as well go all the way, right? besides, I hear you don't get any sedation for sigmoid, and the tube is bigger!). Turns out, he found inflammation in the terminal ileum, which he would not have identified with sigmoid.
Hope this is helpful, and good luck! Don't dismiss your symptoms just because they are mild! Even mild CD impacts your quality of life. It is worth it to find out what is going on.
