What are effective management strategies for impaired fasting glucose and impaired glucose tolerance?
Metadata[+] Show full item record
To prevent progression to diabetes mellitus (DM), patients with impaired glucose tolerance (IGT) and impaired fasting glucose (IFG) are best managed by lifestyle interventions combining dietary modification and moderate-intensity exercise. Medications are less effective. There is no evidence that any of these interventions reduce all-cause mortality or macrovascular outcomes (SOR: A, meta-analyses).
