2. Objectives • Provide knowledge of the pathophysiology, epidemiology, symptoms, & non-pharmacological treatments

3. Obesity • Obesity is a label for ranges of weight that are greater than what is considered healthy for a given height. • Obesity is having an excessive amount of body fat. It increases risk of disease and health problems such as Type 2 Diabetes, Coronary artery disease (CAD), hypertension, stroke, gallbladder disease, cancer, osteoarthritis, and hyperlipidemia. Weight loss can reduce these risks by 10%. • Obesity is a chronic relapsing disease needing management in other disease such as diabetes and hypertension with physical, psychological, and social consequences. • Abdominal obesity, rather than body fat, can be a useful indicator of cardiovascular and cancer related outcomes. Measuring abdominal obesity includes waist circumference, hip circumference, and waist-to-hip ratio.

4. Epidemiology • More than one-third (35.7%) of the adults in the United States are obese in 2009-2010. • Obesity effects all groups in society, irrespective of age, sex, race, ethnicity, socioeconomic status, educational level, and geographic group. • Adults over the age of 60 were more likely to be obese than younger adults.

5. National Prevalence

6. Pathophysiology Hypertophic versus Hypercellular obesity • Hypertrophic obesity usually starts in adulthood and responds to weight reduction measures. • Hypercellulary obesity typically occurs in persons who develop obesity in childhood or adolescence. Hypercellular obesity may find it difficult to lose weight without surgical intervention.
