Obesity

Obesity is defined as an “Excessive fat accumulation in the body to the extent that health and well being are adversely affected”.

People are considered obese when their body mass index (BMI) exceeds 27.5 kg/m2.

As per BMI index it is a stage prior to morbid obesity.

Overweight, obesity and morbid obesity are the fifth leading health risk for global deaths. At least 2.8 million adults die each year as a result of being overweight or obese.

In addition, according to WHO, 44% of the diabetics, 23% of the ischaemic heart disease and between 7% and 41% of certain cancer are attributable to overweight and obesity.

Excessive fat - Obesity

Exercise and diet alone often fails to effectively treat people with extreme and excessive obesity. Bariatric surgery is an operation that is performed in order to help such individuals lose weight. Evidence suggests that bariatric surgery may lower death rates for patients with severe obesity, especially when coupled with healthy eating and lifestyle changes after surgery.

When weight-loss surgery doesn't work

It's possible to not lose enough weight or to regain weight after weight-loss surgery. This weight gain can happen if you don't follow the recommended lifestyle changes. If you frequently snack on high-calorie foods, for instance, you may have inadequate weight loss. To help avoid regaining weight, you must make permanent healthy changes in your diet and get regular physical activity and exercise.

It's important to keep all of your scheduled follow-up appointments after weight-loss surgery so your doctor can monitor your progress. If you notice that you aren't losing weight or you develop complications after your surgery, see your doctor immediately.
