It's too bad this myth isn't true. Unfortunately, someone with diabetes may experience the odd stubbornly high reading even if he's diligently following all his doctors' orders. Type 2 diabetes isn't an easy disease to manage -- and as we age, our bodies are constantly changing, as is our reaction to stress, infections, illness, medications, exercise, and diet. Little wonder, then, that sometimes our blood sugar doesn't cooperate.

It's best to praise a diabetic's hard work when he does hit his recommended range, but don't let an occasional high reading give him the excuse to throw in the towel. If he keeps on following his treatment plan, he'll find that, overall, his glucose control is on target.
