U.S. diabetics are increasingly cutting back on, or even going without, doctor visits, insulin, medicines, and blood-sugar testing as they lose income and health insurance in the recession, an Associated Press analysis has found.

And they end up in emergency rooms more often, patients and physicians said in AP interviews.
