How do you deal with ignorant people?

The past few weeks for the first time in a long time, I have been feeling really good. After my fistula surgery in February, I am now able to power walk an hour a day, with no pain. And have been eating a lot better and counting calories and such. So far I have lost 6 pounds in 3 weeks and I am hoping to continue to lose weight like that consistently. I'm one of the Crohnies that has never been skinny but overweight. So now I am finally able to work on getting my excess weight off.

But, now I am getting comments from people as to when I am going to stop taking my medicine and stop going to that gastroenterologist. They've told me that now that I'm losing weight I can stop going to the GI because he's just using me to make money.

I go to the GI every 4 months to get checked out and get all my blood levels checked. I take Humira once a week, azathioprine twice a day and Vitamin D.

How can I get it through to people that I can't just stop all of my medication like that and stop going to the GI. Or should I just nod and ignore them. It's just really aggravating.

Make a joke that allows them to wonder how ignorant they're being. Don't worry though there are way too many people who speak before educating themselves!

Depending on who they are, I'd just say, "Yeah, too bad if I stopped going I'd die." Then at their surprise, explain the only reason you're feeling better is because it's a CHRONIC condition and you have to keep taking meds.

Or just roll your eyes and say, "If only my intestines would agree with my budget."
