BIOC33H3 Lecture Notes - Stimulus Control, Atherosclerosis, Body Fat Percentage
Document Summary
Obesity is the most common nutritional problem, affecting almost one third of the population. Approximately 13% of americans have a body mass index (bmi) greater than 35 kg/m2. Obesity is the second leading cause of preventable disease in the united states, after smoking. The cause of obesity involves significant genetic/biologic susceptibility factors that are highly influenced by environmental and psychosocial factors. The degree to which a patient is classified as underweight, healthy (normal) weight, overweight, or obese is assessed by using a bmi chart. Individuals with fat located primarily in the abdominal area (apple-shaped body) are at a greater risk for obesity-related complications than those whose fat is primarily located in the upper legs (pear-shaped body). When patients who are obese have surgery, they are likely to suffer from other comorbidities, including diabetes, altered cardiorespiratory function, abnormal metabolic function, hemostasis, and atherosclerosis that place them at risk for complications related to surgery.
