Module A: Prevalence and Pathophysiology of Obesity

CE Credits: 1.0


This module explores the disconcerting trends toward obesity—and how, over the past few decades, the percentage of obese Americans (with a BMI of 30 or above) has exceeded the steady numbers of merely overweight people. It also explores the costs of obesity, both in terms of dollars spent on health issues and the high risk factors for co-morbidities, such as certain cancers and cardiovascular disease. And while many people assume that obesity stems from lifestyle issues, the module also lays out the argument for genetics and heredity in determining the risk factors for obesity. Finally, the module describes the two different kinds or adipose (or fatty) tissue, and the two ways such tissue manifests itself in obesity, as subcutaneous or visceral adipose tissue.

Learning objectives: After completing this module the case manager will be able to:
» Review prevalence, demographics and the economic effects of obesity
» Identify risk factors and co-morbidities associated with obesity
» Describe the role of genetics and genomics in obesity
» Discuss the types of adipose tissue in obesity

Advance your professional practice:: As case managers, understanding the varying causes of obesity can better help us start the process of guiding a patient into successful weight reduction and management. Looking at the diversity of issues that may have brought the patient to the current situation—from cultural factors to underlying illnesses—can help us facilitate the most effective treatment.


Improve organizational performance: Because obesity can contribute to hospitalizations for a variety of acute health problems—from complications of type 2 Diabetes to myocardial infarctions—channeling a team’s resources into helping patients lose weight is a smart investment of time and energy.
