When Does Diabetes Really Start?

For most of my professional life, a diagnosis of diabetes was made when the fasting blood glucose exceeded 140 mg/dL. In 1998, a consensus committee, based on an extensive review of data, changed that to 126 mg/dL. A normal fasting blood glucose was now 100 mg/dL. A glucose between those values is now impaired fasting glucose. Similarly, glucose 2 hours after a meal or glucose load should be 140 mg/dL. A postprandial value becomes diabetes when it exceeds 200 mg/dL. Between 140 and 199 is impaired glucose tolerance. http://www.medpagetoday.com/Endocrinology/Diabetes/48572?xid=nl_mpt_DHE_2014-11-14&utm_content=&utm_medium=email&utm_campaign=DailyHeadlines&utm_source=ST&eun=g721819d0r&userid=721819&email=amydugan2%40gmail.com&mu_id=5883165&utm_term=Daily
