Ask the Doctor: What’s the difference between being overweight and obesity?
Friday, October 10th, 2008Dr. James Lau answers the question: “What’s the difference between being overweight and obesity?”
Obesity means having too much body fat. It is different from being overweight, which means weighing too much. Both terms mean that your weight is greater than what’s considered healthy.
Obesity most often occurs over time when you eat more calories than you burn or use. The balance between calories-in and calories-out differs for everyone. Genetics, overeating, eating high fat foods and being physically inactive are factors that can make you obese.
It’s important to note that obesity is not just a cosmetic concern. Obesity and carrying excess body fat places you at greater risk of developing high blood pressure, diabetes, stroke, arthritis, certain cancers, and other serious health problems. Losing even five to ten percent of your weight if you’re obese can help delay or prevent some of these diseases.
If your body hasn’t responded to diet and exercise, you may be a good candidate for weight loss surgery, or bariatric surgery, such as the gastric bypass or the lap band using laparoscopic techniques. It’s important to get the facts about your choices if you believe you’re a good candidate for weight loss surgery.
The University of Nevada School of Medicine and University Medical Center sponsors free seminars in Las Vegas on bariatric surgery that Dr. Shawn Tsuda and I personally conduct. These free seminars are usually held once or twice a month at the School of Medicine. For a complete schedule, and for more information, please contact Robin Morello at 702-671-5150.
