Obesity is not just a cosmetic consideration. It is a chronic condition defined by an excess of total body fat. Obesity results from a complex interaction of genetic, behavioral and environmental factors causing an imbalance between energy intake and energy expenditure, it is best defined by using the body mass index.
The balance between calorie intake and energy expenditure determines a person's weight. If a person eats more calories than he burns (metabolizes), he will gain weight (the body will store the excess energy as fat). If a person eats fewer calories than he metabolizes, he will lose weight. Therefore the most common causes of obesity are overeating and physical inactivity.
There are a wide variety of health consequences due to obesity including:
• Coronary heart disease
• Type 2 diabetes
• Cancers (endometrial, breast and colon)
• Hypertension (high blood pressure)
• Dyslipidemia (high total cholesterol or high levels of triglycerides)
• Liver and gallbladder disease
• Sleep apnea and respiratory problems
• Osteoarthritis (a degeneration of cartilage and its underlying bone within a joint)
• Gynecological problems (abnormal menses, infertility)
Body mass index or BMI is a wonderful tool to find whether one's weight is in the normal range or not. This is expressed by a simple formula as weight in the kilogram divided by height in meter square.
BMI=Weight in kg / height in m2 According to the World Health Organization (WHO), BMI is classified as:
|Classification||Ideal BMI||Overweight||Obese||Severely Obese||Morbidly Obese|
• Diet and exercise
• Behavior modification
Due to the high failure rate in maintaining weight loss after medically supervised diets, surgery has proven to be the most effective and only durable treatment for morbidly obese patients. It delivers long-term weight loss, with minimal morbidity and mortality, and also improves or achieves complete remission for several of the comorbidities associated with the disease.
"Only surgery has proven effective over the long term for most patients with clinically severe obesity."
If your BMI is 40 or greater or if your BMI is more than 35 or higher with one or more of the following, you could physically be a candidate for bariatric surgery:
• High blood pressure
• Coronary artery disease
• High levels of fats in the blood (hyperlipidemia)
• Breathing difficulties during sleep (apnea and hypoventilation)
