Definition of Obesity Our Obesity Main Article provides a comprehensive look at the who, what, when and how of Obesity Obesity: The state of being well above one's normal weight. A person has traditionally been considered to be obese if they are more than 20 percent over their ideal weight. That ideal weight must take into account the person's height, age, sex, and build. Obesity has been more precisely defined by the National Institutes of Health the NIH as a BMI of 30 and above. A BMI of 30 is about 30 pounds overweight. The BMI body mass index, a key index for relating body weight to height, is a person's weight in kilograms kg divided by their height in meters msquared. Since the BMI describes the body weight relative to height, it correlates strongly in adults with the total body fat content. Some very muscular people may have a high BMI without undue health risks. Obesity is often multifactorial, based on both genetic and behavioral factors. Accordingly, treatment of obesity usually requires more than just dietary changes. Exercise, counseling and support, and sometimes medication can supplement diet to help patients conquer weight problems. Extreme diets, on the other hand, can actually contribute to increased obesity. Overweight is a significant contributor to health problems. It increases the risk of developing a number of diseases including: Type 2 adult-onset diabetes High blood pressure hypertension Stroke cerebrovascular accident or CVA Heart attack myocardial infarction or MI Heart failure congestive heart failure Cancer certain forms such as cancer of the prostate and cancer of the colon and rectum Gallstones and gall bladder disease cholecystitis Gout and gouty arthritis Osteoarthritis degenerative arthritis of the knees, hips, and the lower back Sleep apnea failure to breath normally during sleep, lowering blood oxygen Pickwickian syndrome obesity, red face, underventilation, and drowsiness.
