Obesity: Health Risks, Diagnosis and Treatment.

What is obesity?

Obesity is considered based on the weight of a person compared to the height and has become a very important parameter of determining the level of fitness in people.

An internationally accepted index used by experts to determine who is and who is not obese is called the Body Mass Index (BMI). The BMI accepted as normal, ranges between 18 and 28, and any one above the upper limit is classified as an obese person. The more obese a person is, the more likely he or she is to develop health problems.

Further grading considers the severity of obesity by classifying obesity into mild, morbid and malignant obesity. Mild obesity involving a body mass index (BMI 30+) causes less morbidity than morbid obesity (BMI 40+) or malignant obesity (BMI 50+). Malignant obesity is the most dangerous and these people are very prone to heart attacks. For example, someone who is 40 percent overweight is has a two-fold chance of dying a premature death than the other person whose BMI is within normal range. So it is an issue of life and death we are talking about.

So to simply put it, obesity is excessive body fat.
