If it feels like being a Diabetic extends to every fiber of your being, its basically because it does. I know, I was shocked too.
One of the most important aspects is to take care of your mouth, teeth, and gums. I have never been one to floss daily, or even very regularly, but I have been working on making this a habit, because it is one of those little things that can have a huge impact on your Diabetes, and your overall health.
My last few dental visits have gone much better than ones prior, which means I am getting better about taking care of my teeth, and by extension, my health and my Diabetes. I am still nowhere near perfect, but I am working on being much better.
