GDM and T2D The prevalence of T2D in the Netherlands is 600.000-800.000 and each year ~70.000 new patients are diagnosed. Patients with T2D have a 2-4 times increased risk of developing cardiovascular disease. These complications seriously decrease the quality of life and life expectancy of T2D patients. The burden of this disease not only affects these patients but our society as well. Health care costs with respect to diabetes amounted to 814 million euro in 2005 in the Netherlands and indirect costs because of absence of work are unknown but thought to be substantial.
