A new system proposed by Canadian and US obesity researchers may provide another weapon obesity treatment. University of Alberta obesity expert Dr. Arya Sharma, along with a researcher from Northwestern University in Chicago, Illinois, has proposed a classification system to help doctors assess and treat overweight patients.Until now, obesity has been mostly defined by body measurements. Measurements like body mass index (BMI) and waist size are used as guidelines to tell doctors whether their patients are within a healthy weight range. But these measurements are based on population studies, rather than on individual patients, so they don't provide doctors with a full picture of a patient's health issues."We know that obesity can lead to a whole host of health problems, including heart disease, diabetes, cancer, kidney disease, fatty liver disease, osteoarthritis, sleep apnea and depression. But increased body fat alone doesn't necessarily imply or reliably predict these health problems," says Sharma, Chair of Obesity Research and Management at the University of Alberta's Faculty of Medicine & Dentistry and the Medical Director of Weight Wise at Alberta Health Services. "Two patients with the same BMI or waist size can have wildly different health issues that require different treatment approaches; these anthropometric measurements should be complemented by a clinical staging system that provides a meaningful framework for diagnosing and managing obesity."The Edmonton Obesity Staging System, outlined in the current online issue of the International Journal of Obesity, has five stages of obesity, from stages 0-4. The first stage, stage 0, would fit patients with no symptoms of obesity-related health problems. The last stage, stage 4, would fit patients that have the most severe obesity-related health problems. The system is simple for doctors to use – they can easily classify their patients by doing simple tasks like taking their patients' medical history, doing a physical exam and taking routine tests like blood sugar and cholesterol levels. The system will also provide doctors with specific treatment approaches for each stage.(...)You can read the whole article at: ExamHealth.com (published: 2/10/2009)
