  • Obesity is recognized as a chronic, debilitating and potentially fatal disease. Obesity has approached smoking as a leading cause of preventable death. Obesity and excess weight are associated with: Type 2 Diabetes (wt gain of 11-18 # increases risk x2) Hypertension (High Blood Pressure) – 2X more common Cardiovascular Disease (Heart Attack and Stroke) Stroke High Cholesterol (Incrs Trig, decrs HDL) Osteoarthritis (Every 2# incrs in wt = 9-13% incrs in arthritis) Sleep Apnea Gallbladder Disease Certain Types of Cancer (endomet,colon,GB,prost,kidny,breast) Female Infertility Obese individuals have a 50 to 100% incrsd risk of premat death Overwt adolescents have 70% chance of becoming overwt adults 300,000 deaths calculated, due to diet and sedentary lives
  • Physicians know that even a 5 to 10% weight loss can produce significant health benefits, yet we recognize that many of our patients have difficulty achieving permanent weight loss. Our patients want to lose the weight and are desperate for a quick fix, making them easy targets for this billion-dollar industry. Current popular interventions include diets based on limiting caloric intake by counting calories, fat grams, or by restricting certain foods such as carbohydrates. Another option is medically supervised very low calorie diets or liquid fasts. Prescription and non-prescription weight loss medications remain in high demand despite reports of significant complications. There has been resurgence in popularity of bariatric surgery due to media attention. Exercise regimens remain an important part of most weight loss programs. Interventions recommended by the National Heart, Lung and Blood Institute Clinical Guidelines include low calorie diets, increased physical activity, and behavior therapy. Weight loss medications and surgical interventions may be appropriate for carefully selected patients.
