Introduction
Term coined by the American Diabetes Association & the National Institutes of Health referring to persons whose blood glucose is higher than normal, but not high enough to reach criteria for diabetes mellitus.
Epidemiology
- 38% if Americans with prediabetes[13]
Laboratory
- fasting plasma glucose:* 100-125 mg/dL
- oral glucose tolerance test (2 hour): 140-199 mg/dL
- hemoglobin A1c of 5.7-6.4%[5]
* previously 110 mg/dL
Complications
- most of these persons will develop diabetes within 10 years
- higher risk of heart disease & stroke (RR = 1.2)[7][15]
- peripheral neuropathy
- prevalence based on Michigan Neuropathy Screening Instrument scores = 49%*
- in analysis based on neurothesiometer readings, prevalence = 5-10% not different from euglycemic subjects[11]
* 29& in euglycemic subjects & 50% in diabetics
Management
- life-style changes prevent progress to type 2 diabetes (41% vs 58%)[4]
- modest weight loss
- modest aerobic exercise
- patients with prediabetes who achieve normal glucose regulation, even transiently, are less likely to develop diabetes[6]
- short bouts of walking (15 minutes) after meals may be more effective than a single longer walk (45 minutes) in controlling postprandial hyperglycemia in older adults[8]
- American Diabetes Association recommendations
- nutritional therapy[17]
- metformin for treatment of prediabetes in patients < 60 years, BMI > 35, or with history of gestational diabetes[4]
- orlistat, acabose or voglibose, or thiazolidinedione also shown to delay onset of diabetes by up to 3 years[4]
- lorcaserin (Belviq) may promote weight loss & slow progression to type 2 diabetes & promote remission of type 2 diabetes[16]
- vitamin D of no benefit in preventing progression of prediabetes to type 2 diabetes
- after 21 years of followup, mortality similar in patients with prediabetes randomized to lifestyle intervention, metformin, or placebo[19]
* preferred over diet & lifestyle changes[4], orlistat, acarbose or thiazolidinediones (no references cited)
