The prevalence of type 2 diabetes continues to increase at an alarming rate around the world, with even more people being affected by prediabetes. Although the pathogenesis and long-term complications of type 2 diabetes are fairly well known, its treatment has remained challenging, with only half of the patients achieving the recommended hemoglobin A1c target. This narrative review explores the pathogenetic rationale for the treatment of type 2 diabetes, with the view of fostering better understanding of the evolving treatment modalities. The diagnostic criteria including the role of hemoglobin A1c in the diagnosis of diabetes are discussed. Due attention is given to the different therapeutic maneuvers and their utility in the management of the diabetic patient. The evidence supporting the role of exercise, medical nutrition therapy, glucose monitoring, and antiobesity measures including pharmacotherapy and bariatric surgery is discussed. The controversial subject of optimum glycemic control in hospitalized and ambulatory patients is discussed in detail. An update of the available pharmacologic options for the management of type 2 diabetes is provided with particular emphasis on newer and emerging modalities. Special attention has been given to the initiation of insulin therapy in patients with type 2 diabetes, with explanation of the pathophysiologic basis for insulin therapy in the ambulatory diabetic patient. A review of the evidence supporting the efficacy of the different preventive measures is also provided.
OBJECTIVETo assess the relative impact of an intensive lifestyle intervention (ILI) on use and costs of health care within the Look AHEAD trial.RESEARCH DESIGN AND METHODSA total of 5,121 overweight or obese adults with type 2 diabetes were randomly assigned to an ILI that promoted weight loss or to a comparison condition of diabetes support and education (DSE). Use and costs of health-care services were recorded across an average of 10 years.RESULTSILI led to reductions in annual hospitalizations (11%, P = 0.004), hospital days (15%, P = 0.01), and number of medications (6%, P < 0.001), resulting in cost savings for hospitalization (10%, P = 0.04) and medication (7%, P < 0.001). ILI produced a mean relative per-person 10-year cost savings of $5,280 (95% CI 3,385–7,175); however, these were not evident among individuals with a history of cardiovascular disease.CONCLUSIONSCompared with DSE over 10 years, ILI participants had fewer hospitalizations, fewer medications, and lower health-care costs.
Objectives: This study aimed to assess the prevalence rates of type 2 diabetes and to determine potential associated risk factors of the disease in Port Harcourt, Nigeria. Research design and methods: Five hundred and two (502) subjects aged above 40 years, obtained by a two-stage cluster sampling technique participated in this survey. Casual (random) plasma glucose estimations were done for all subjects after relevant personal data were obtained. Subjects with casual plasma glucose (CPG) ]/7.0 mmol/l had oral glucose tolerance tests (OGTT) done. Fasting and 2 h post glucose load blood samples were analyzed for plasma glucose levels. Results: Thirty-four (34) subjects had diabetes, giving a crude prevalence rate of 6.8% (CI 0/4.6 Á/9.0%), and standardized rate of 7.9%. The crude prevalence rates were 7.7 and 5.7% for males and females, respectively. Of the 34 diabetic subjects seen, 14 (41.2%) of them were not previously known to have diabetes; 83.7% of these were asymptomatic. Body mass index (BMI) ]/25 kg/m 2 and WHR ]/0.85, family history of diabetes, physical inactivity, heavy consumption of alcohol, older age as well as high social status and Hausa Á/Fulani or Ibibio origin were associated with significantly higher prevalence of type 2 diabetes. Conclusion: The prevalence of type 2 diabetes in Port Harcourt is relatively high. Changing lifestyle associated with industrialization may explain this. A significant proportion of the diabetic subjects are asymptomatic and undiagnosed. The risk factors as shown in our study clearly emphasize the point that type 2 diabetes is to a large extent a preventable disease. #
Black and white offspring of parents with type 2 diabetes develop prediabetes at a similar high rate of approximately 11% per year. Therefore, close surveillance, with prompt intervention to prevent dysglycemia, is warranted in persons with parental diabetes.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
