Obesity, diabetes mellitus type II, and hypertension are epidemic problems in Americanized societies and increasingly worldwide. Approximately 1/3 to 1/2 of Americans are obese and/or diabetic and/or hypertensive. Whereas diabetes and hypertension had previously been found almost exclusively among older adults, we find these conditions occurring more commonly among children; this trend indicates a clear change in “the total environment” and directs us away from so-called genetic causes of these conditions. This course specifies the diagnostic criteria, history, physical exam, laboratory assessment, and treatment plans for the related conditions of obesity, diabetes mellitus type two, metabolic syndrome, chronic hypertension and high blood pressure. Course materials will be delivered via PDF documents and peer-reviewed articles, printed materials, prerecorded video lectures, and live sessions.
