Obesity is one of the most common health conditions in the world. It affects more than 650 million adults worldwide. Morbid obesity is the most severe form of obesity. Obesity means excess collection of fat. And obesity is emerging as a health epidemic around the world. today we have a pandemic of obesity and related diseases.But being obese is different from being overweight. An adult male is obese when his weight is 20% or more over the most desirable for their height. A woman is obese at 25% or more than this weight. Anyone more than 40 kg overweight is considered morbidly obese.Obesity increases a person’s risk of illness and death due to diabetes, stroke, coronary artery disease, hypertension, high cholesterol, and kidney and gallbladder disorders. Obesity may increase the risk for some types of cancer. It is also a risk factor for the development of osteoarthritis and sleep apnea.
Body Mass Index (BMI) is measure of body fat based on height and weight that applies to both adult men and women. BMI does not differentiate between body fat and muscle mass. Therefore, body builders and people who have a lot of muscle bulk will have a high BMI but are not overweight or obese.BMI is usually a good indicator of body fat for most people. Although it doesn’t directly measure body fat, it closely correlates to direct measures of body fat, such as underwater weighing. BMI is also an inexpensive and easy-to-perform method that can help determine if a person’s current weight could potentially lead to health problems.It’s important to note that BMI is not a diagnostic tool. Whether a person has a high BMI or low BMI, an individual’s personal measurement should be left to a reputable doctor to determine if excess weight is a health risk.
