What is Obesity?
Obesity is a life-long progressive, life threatening condition marked by the excess accumulation of body fat, which can significantly reduce life expectancy. When weight reaches extreme levels, it is called MORBID OBESITY and is a chronic condition with numerous medical, psychological and social consequences. Finding out if you are obese is simple; you calculate your Body Mass Index or BMI. Obesity is also defined by waist size - over 90 cm in males and over 80 cm in females.
How can Obesity affect you?
Obesity is rarely just a physiological problem. This disorder has far reaching effects; physiological, psychological and social. On the physical front, obesity can lead to several complications that could be fatal or incapacitating if left untreated.
Some of the most common diseases that are directly and indirectly linked to obesity are:
How to manage Obesity?
Obesity can be treated. But it involves more than just swallowing a pill or sticking to a diet. It needs a multidisciplinary assessment involving a coordinated approach by different specialists such as dietician, endocrinologist, psychologist, internist, cardiologist, family doctor, bariatric surgeon.
What is Bariatric (Obesity) Surgery?
Bariatric (Obesity) surgery, or weight loss surgery or metabolic surgery, includes a variety of procedures performed on people who are obese. Weight loss is achieved by reducing the size of the stomach through removal of a portion of the stomach (sleeve gastrectomy) or by resecting and re-routing the small intestines to a small stomach pouch (gastric bypass surgery).
Why should I consider Weight Loss Surgery?
Because it works! Surgical treatment for obesity is the ONLY treatment that reliably produces significant and sustained weight loss. People with clinically severe obesity are at great risk for developing many associated medical conditions. Research has shown that surgical treatment results in significant weight loss and improvement in most problems associated with obesity. Surgical treatment for clinically severe obesity has been endorsed by the National Institutes Of Health, the World Health Organization, the American Heart Association, the American Dietetic Association, and the American Obesity Association.
Does my weight alone justify such extreme measures?
Yes. Morbid obesity is an independent risk factor for premature death, with the risk rising as the BMI increases.
People with a BMI of 30 have a relative risk of dying early that is 1.3 times greater than normal weight individuals. By the time the BMI is 40, the risk is close to 3 times as great.

Vertical Sleeve Gastrectomy (VSG)- How it works to help you lose weight?
The Vertical Sleeve Gastrectomy (VSG) generates weight loss solely through gastric restriction (reduced stomach volume). In VSG approximately 2/3rd of the stomach is stapled off along its greater curvature, leaving behind 1/3rd stomach along lesser curvature, which is roughly the size and shape of a Banana or Sleeve. This operation does not involve any “rerouting” or reconnecting of the intestines. Hence it is technically a simpler operation than the gastric bypass.
Gastric bypass -How it works to help you lose weight?
Food absorption is normal, with no malabsorption. It is known to reduce hunger because Ghrelin (hunger stimulating hormone) producing part of stomach is removed. Provides satiety with small amount of food and unlike gastric band & gastric bypass, patients feels full with liquids as well. Under this procedure, a small stomach pouch is created and section of the small intestine is directly attached to the pouch. By creating a smaller stomach pouch, a Gastric Bypass limits the amount of food that can be eaten at one time, so you feel full sooner and stay full longer. It also causes your body to absorb fewer calories.
As you eat less food and absorb fewer calories, your body will stop storing excess calories and start using its fat supply for energy.
MINI GASTRIC BYPASS - How it works to help you lose weight?
It’s a combination of both the procedure where a gastric tube is made with is further joined with small intestine bypassing certain length of small bowel. Here patient can eat its normal amount of food but later it’s absorbed less in small intestine.
