The New York Times' Tara Parker-Pope reports on a recent study that shows people regularly underestimate the severity of diabetes as a health concern.
When I was in grad school in the early 1990's, I worked one summer doing intake interviews for a low-vision study at a VA Hospital. I remember two things, in particular: Of the low-vision patients I interviewed, most had diabetes and many were missing limbs (typically feet and legs). Turns out diabetes damages your body in all kinds of ways.
So, when I came up a couple of years in a row with blood sugar numbers that were 'pre-diabetic', you can believe I took it seriously. Here's a helpful site from the American Diabetes Association. It's good food and lots of exercise, not rocket science!
