Hi Lizzie,
Forgot to say that Crohn's advice is a diet containing refined carbs, the worst thing out for blood sugars. It is a balancing act to control the two and nigh impossible at times.
For anyone who does not know about Crohn's, you get no warning and can be doubly incontinent at times.
I find Imodium is my best friend for Crohn's and a meter is my best friend for Diabetes.
