Type 2 diabetes: 'Intensive' versus 'conventional' blood glucose control -- no clear picture

Research published in The Cochrane Library found that the risk of death and cardiovascular disease, such as stroke, was unchanged whether glucose control was intense or conventional. They did find, however, that when aiming to keep blood glucose levels at the lower intensive level, the chance of damaging small blood vessels in the body, potentially leading to damage in the eyes and kidneys, is reduced. But aiming for this lower level with the more intensive glucose control substantially increased the risk that a person's blood glucose could drop too low, potentially resulting in loss of consciousness or even death if untreated.
