There’s going to be a lot of talk about this; a study out of the Mayo Clinic questions the need for people with Type 2 diabetes to tightly control their blood sugar. Diabetes specialist Dr Victor Montori has been searching through the medical literature, looking for proof to support the widely held belief and says he can’tr find any. He says our thinking may have been flawed.

Millions of people are taking glucose-lowering drugs, but with that comes the risk of side effects including weight gain, dizziness and coma. More information here and here.
