Comprehensive Weight Management Clinic

If you’re struggling with your weight, you’re not alone. More than one-thirds of Indians are currently overweight or obese and many have medical conditions that affect their weight. Some have tried various diets and fitness programs with little or no success. With so much available nutrition and weight loss information, most people don’t know what are the scientific and safe medical options to achieve a healthy sustainable weight.

What is obesity

Obesity is not just about extra fat in body. It is a complex disorder of multiple etiologies characterized by excess body fat that threatens or affects not only physical and mental health but also has social and economic consequences. Obesity has been recognized as a “chronic disease” by number of health organisations across the world including “World Health Organization”.

How is obesity measured?

Obesity is measured with the help of two tools: BMI (Body mass index) and WC (Waist circumference). BMI is a tool calculated from a person’s height and weight, and used to analyse and determine whether he/she is overweight, underweight or health. BMI is calculated by dividing the weight (in kilograms) of a person by his height in meters squared.

That is, BMI = weight in kg/(height in m)2
As per the Indian standards, BMI more than 23 amounts to overweight and BMI more than 27.5 amounts to obesity.

Along with BMI, the distribution of body fat is very important. Waist circumference is a very good indicator of unhealthy fat (central obesity) in your body. For people of Indian origin, WC of more than 90 cm in men and more than 80 cm in case of women is abnormal.

How does obesity affect your health?

Obesity if left untreated can affect your health on numerous fronts. Some of the common problems related to obesity are type 2 diabetes, high blood pressure, high cholesterol, heart problems, fatty liver, chronic kidney disease, polycystic ovarian syndrome, infertility, gall stones, osteoarthritis, obstructive sleep apnea, benign intracranial hypertension, gastroesophageal reflux, urinary incontinence, repeated fungal infections of skin, depression, anxiety. Obesity is also a risk factor for variety of cancers.

  • Partial meal replacement therapy
  • Pharmacological therapy along with one of the above.

The Bariatric surgical program is led by our surgeon who performs bariatric surgeries in carefully selected candidates after thorough evaluation by the team.

What is Bariatric (Obesity) Surgery?

Bariatric surgery promotes weight loss by restricting food intake and, in some procedures, altering the digestive process. As with other treatments for obesity, the best results are achieved when combined with healthy eating behaviours and
regular physical activity.

Members of our interdisciplinary team complete both medical and psychological assessments on patients considering bariatric surgery because not everyone is an appropriate candidate for this surgery. Patients must be emotionally and physically ready for surgery because it requires significant lifestyle changes including taking vitamin supplements as well as adhering to dietary restrictions and routine physical activity.

How will Bariatric Surgery help you?

  • Improve your quality of life (better movement, physical and mental health, social activities, medications and overall well-being)

Laparoscopic Sleeve Gastrectomy

Laparoscopic Sleeve Gastrectomy is a restrictive procedure, which involves removal of 60-75% of the stomach, leaving a narrow gastric tube or sleeve. No intestines are removed or bypassed. This procedure will result in approximately a 50% loss of excess body weight in the first 6-12 months.


Roux-EN-Y is a laparoscopic surgical procedure that combines restrictive and malabsorptive components. It decreases the size of the stomach to about one-ounce capacity and bypasses part of the small intestine to decrease absorption. This is the most commonly performed weight loss surgery and you can expect to lose about 80% of your excess body weight within 12 months


The mini-gastric bypass procedure has gained popularity in recent years.The mini-gastric bypass procedure is restrictive and malabsorptive. This means that the procedure reduces the size of your stomach, restricting the amount you can eat. The procedure also reduces absorption of food by bypassing up to 6 feet of intestines. Mini-gastric bypass is a quicker operation compared to traditional laparoscopic gastric bypass surgery. Operating times are reduced, on average by 50 minutes.
