Defining Obesity

Obesity has indeed reached epidemic proportions in the United States.

The federal government estimates that 97 million Americans - one third of the entire population - is overweight or obese. This severe health risk is now affecting both adults and children.

Obesity is much more than being overweight. The body mass index (BMI) is the standard by which obesity is measured. The BMI calculates various components based upon your height and weight. Those with a BMI less than 25 and above 18.5 are considered to be within optimal weight. Individuals with a BMI of 30 or above are considered obese. Severe or morbid obesity is used to describe anyone with a BMI in excess of 40.

Obesity brings with it an array of health risks that can lead to severe complications and death. Heart disease, type 2 diabetes, sleep apnea, and other medical conditions are often the result of being obese. Morbid obesity complicates matters even more than general obesity.

Since obesity is usually the result of gaining weight over an extended period of time, it is difficult to reduce body weight in a rapid manner without surgical measures. Dieting, exercise, and medications are often initial steps to controlling weight. However, when these less aggressive methods fail, weight-loss surgery may be an option for some people.
