What is
Obesity
Obesity is a medical condition in which excess body fat has
accumulated to the extent that it may have an adverse affect on
health. It is a life-long progressive, life threatening disease which
can significantly reduce life expectancy
When weight reaches extreme levels, it is called MORBID
OBESITY which is prone to develop numerous medical,
psychological and social consequences
It can be defined based on the Body Mass Index into various
categories as shown below
BMI Classification:
BMI = wt (kg) / [ht (m )]
2
BMI is a useful general guideline and is a good estimator of body
fat for most adults between 19 and 70 years of age
However, it may not be an accurate measurement of body fat for
body builders, certain athletes, and pregnant women
Healthy weight is defined as BMI equal to or greater than 19 and
less than 25
BMI greater than or equal to 25 is overweight
BMI greater than or equal to 30 is obesity
BMI 35 or 40 is severe obesity
BMI of 35 or 40 - 44.9 or 49.9 is morbid obesity
A BMI of 45 or 50 is super obesity
Obesity is also defined by waist size - over 90 cm in males and
over 80 cm in females
With every single increase in BMI, the chances of developing
diseases like Diabetes, Hypertension increases

3. BariatricSurgery/WeightLossSurgery
Bariatric surgery is refer to any surgery performed on stomach
or intestine with intent to cure obesity and its co morbidities
likediabetes,hypertension,highcholesterollevelsetc.,
Principlesofthesurgeryare
• Reducing the appetite by lowering the blood levels of the
ghrelin,theappetite hormone
• Limiting the capacity of food intake at one point of time so
thatthebodycanmetabolizetheingestedfoodfaster
• Reducing the absorption of food consumed hence by
limitingthedepositionofadditionalfat
• Increasingtheburningcapacityofthebody(BasalMetabolic
Rate)hencebythrowingawaytheexcessfat
Treating
Obesity
The basic principles in treating obesity are
• Diet and Healthy Eating: Healthy eating and eating less calories with
increased physical activity and modified life style habits is the easy
way to reduce weight. A registered dietitian can help to design a diet
suitablefortheindividual's need alongwiththephysicalactivityplan
• : Weight-loss medicines of various kinds are available inMedications
the market, but at GEM OBESITY & DIABETES SURGERY CENTRE
we do not recommend them as most of these preparations have more
adversesideeffectscomparedtotheirbenefits
Types of
Surgical Procedures
First centre
in the country
to have performed
Laparoscopic
Gastric bypass
4 5
Laparoscopic Adjustable Gastric Banding - LAGB
Laparoscopic Adjustable Gastric Banding is a reversible procedure for weight loss. This
laparoscopic procedure involves the placement of a silicone band around the upper part of the
stomach. That results in the creation of an hour glass stomach, with a small outlet that allows food
to enter into the lower part of the stomach
This procedure is especially beneficial for large eaters, or those who have tried to lose weight
several times but haven't been able to. Generally this procedure is recommended for younger
patients, as it is reversible. With this procedure one can lose about 40-50% of their excess weight
within 18 months, but patient understanding and compliance is the most important
Sleeve Gastrectomy - SG
Sleeve Gastrectomy is an irreversible procedure that curtails the size of the stomach, this
operation surgically removes two thirds of the left side of the stomach. This results in a new
stomach which is roughly the size and shape of a banana and looks like a sleeve or a tube.
Among the bariatric procedures, sleeve gastrectomy is the most commonly performed
procedure. Sleeve gastrectomy is a restrictive form of weight loss surgery that limits the capacity
of the stomach to 60 cc - 150 cc. Unlike other forms of bariatric surgery, the outlet valve and the
nerves to the stomach remain intact
This procedure also eliminates the hunger inducing hormone called 'Ghrelin', hence patient feels
full after consuming small amounts of food, and lose weight quickly
ROUX en Y Gastric Bypass - RYGB
Laparoscopic Roux en Y Gastric Bypass procedure is a weight loss surgery that involves the
creation of a small stomach pouch with the help of staples that restricts food intake. In addition the
initial segment of the small intestine is bypassed. As a result the food directly enters the jejunum.
This leads to malabsorption of consumed food. This procedure also eliminates the hunger
inducing hormone "Ghrelin". All these mechanisms contribute to significant weight loss
“It can also successful in control of type II diabetes in the short / long term"
Single Incision Multiport Bariatric Surgery - SIMP
Single incision surgery or single-incision laparoscopic bariatric surgery is one of the most
spectacular innovations in the field of minimal access surgery. As the name suggests single
incision surgery is performed through a single incision in the navel. It is essentially a scarless
procedure as the scar gets hidden deep into the navel. Among the bariatric procedures, sleeve
gastrectomy is the most commonly performed procedure using this technique

Obesity is rarely just a physiological problem. This disorder has far reaching

(NIDDM) has the strongest association with obesity. In type II diabetes, the

CardiovascularDiseaseandHypertension
Obesity is one of the important factor for this Cardiovascular Disease (CVD)
includes Coronary Heart Disease (CHD), stroke and peripheral vascular
disease. These diseases account for up to 33% of deaths in most
industrialized countries - a figure that's increasing rapidly in developing
countriesaswell
Cancer
Several studies have found an association between obesity and the
incidence of certain cancers, particularly of hormone-dependent and
gastrointestinal cancers. Obese women have been proved to be at greater
risk of breast, endometrial, ovarian and cervical cancers. There is also
evidence for higher risk of prostate and rectal cancer in men. Obesity also
