What is Obesity ?
The Centre for Disease Control defines obesity as an excessively high amount of body fat in relation to lean body mass. It is commonly measured by Body Mass Index (BMI), which calculate the relationship of weight to height. An adult with a BMI of 30 or more is considered obese. Use the chart on page 35 to calculate your BMI.
Obesity becomes morbid obesity when an adult is 45 kgs or more over ideal body weight, has a BMI of 40 or more, or has a BMI of 35 or more in combination with a health related conditions such as obstructive sleep apnea or a disease such as type 2 diabetes or heart disease
Obesity dramatically increases the risk of :
- High blood pressure
- High levels of triglycerides (a type of blood fat)
- Type 2 diabetes
- Heart disease and stroke
- Obstructive sleep apnea
Higher body weights are also associated with cancer and early death
Most nonsurgical weight loss programs are based on a combination of diet, behavior modification, and regular exercise. However, published scientific papers report that these methods do not help resolve morbid obesity because they fail to help people maintain weight loss. In fact, more than 95% of people regain the weight they lose within a few years after treatment.
Several factors can contribute to weight gain. Diet and exercise programs address factors that can be modified, such as lifestyle and behavior. However, because these methods fail to help so many people achieve and maintain a healthier weight, medical scientists are investigating another proven factor: family history. Their research points to a strong link between our genetic makeup (which we were born with) and obesity. Other studies have identified substances that act on the brain to signal a need for an increase in food intake. This information may help explain why diet and exercise programs have not worked for you.
Over the last decade, weight loss surgery has been continually refined results and minimize risks. Today, bariatric surgeons have access to substantial body of clinical data that support the use of surgery as a safe and effective weight loss treatment when other methods have failed.
Compared to other weight loss methods, such as dieting, surgery provides the longest period of sustained weight loss in patients for whom all other therapies have failed.6 It has also been shown to improve many obesity-related health conditions, such as type 2 diabetes and high blood pressure.
