Bariatric Surgery

“Motivation is what gets you started, habit is what gets you going.”

Morbid obesity or clinically severe obesity has emerged as one of the most dreaded diseases of this century. People who have attempted to lose weight, know how difficult it is to not only lose weight but also to maintain the weight loss. On a daily basis, we see patients who put in their heart and soul into their efforts to lose weight. They have been to every weight loss clinic, celebrity dieticians, gyms, yoga gurus and weight loss retreats. Unfortunately, more often than not, they meet with disappointment and tend to yo-yo between weight loss and weight gain. This entire process is extremely disheartening and demotivating for the patients.

So, if you have tried hard to lose weight without success and the weight is bearing you down, you have come to the right place because bariatric surgery is the only way at the moment that can lead to sustained weight loss in morbidly obese patients.

Bariatric surgery/ weight loss surgery/ obesity surgery is the only proven method for sustained weight-loss in morbidly obese patients.

Obesity is classified as under: 

  Classification for Caucasians/ Westerners(Kg/m2)

Classification for Asians


Normal weight 18.5 - 25 18.5 – 23.5
Overweight 25 - 30 23.5 – 27.5
Class 1 obesity 30 – 35 27.5 – 32.5
Class 2 obesity 35 - 40 32.5 – 37.5
Class 3 obesity 40 and above 37.5 and above

BMI Formula:

BMI= (weight in kg)/Height in m2)

Obesity affects every organ of human body. Obese people are at an increased risk of developing type 2 diabetes, high blood pressure, dys-lipidemia and subsequently heart disease. Obesity also leads to obstructive sleep apnoea, non-alcoholic fatty liver disease, gout, joint diseases, PCOD,  increased risk of venous thrombo-embolism, gall bladder stones etc. Obese patients are also at a high risk for developing certain kind of cancers such as breast and endometrial cancer in women and colon and pancreatic cancers in men.

Bariatric Surgery

Bariatric surgery or obesity surgery is the only proven method that leads to sustained weight loss in patients with clinically severe obesity. It also leads to a significant improvement in most of the associated diseases such as diabetes, high blood pressure, high cholesterol etc and reduces overall risk of heart disease. Most bariatric surgery or obesity surgery procedures lead to about 60 to 75% excess weight loss.

Guidelines for weight loss surgery

The IFSO- APC (International Federation for Surgery for Obesity and Metabolic Disorders - Asia Pacific Chapter) guidelines for weight loss surgery are as under:

  • Bariatric surgery/obesity surgery/weight loss surgery must be considered for the treatment of obesity for acceptable Asian candidates with BMI ≥ 35 Kg/m2 with or without any associated diseases.
  • Bariatric surgery/metabolic surgery must be considered for the treatment of type 2 diabetes or metabolic syndrome for patients who are inadequately controlled by lifestyle alterations and medical treatment for acceptable Asian candidates with BMI ≥ 30 Kg/m2.
  • Bariatric surgery/metabolic surgery may also be considered as a non-primary alternative to treat inadequately controlled type 2 diabetes or metabolic syndrome for suitable Asian candidates with BMI ≥ 27.5 Kg/m2.

Types of bariatric surgery

Bariatric surgery is an evolving branch of medicine. Bariatric surgeries performed at our hospital include:

  1. Laparoscopic Roux en y gastric bypass
  2. Laparoscopic sleeve gastrectomy
  3. Laparoscopic adjustable gastric banding (not very popular any more)
  4. Endoscopic intra-gastric balloon insertion
  5. Laparoscopic single anastomosis gastric bypass (mini-gastric bypass)

Selection of the type of bariatric surgery

Which procedure suits you the best depends on many factors which include the patient’s age, gender, weight, food habits, associated diseases, team and patient commitment etc. In our practice, you as the patient are equally involved in the decision making. Once we evaluate you, the final decision about the procedure is taken after a mutual discussion between the doctor and the patient. Bariatric surgery is all about a lifestyle change and best results can be achieved only if the doctor and the patient work together as a team.

Preparing for surgery

Getting any surgery done is a major decision. Having faith in your doctor and the team is very important. We understand that surgery can be an intimidating experience for some people. Hence, we believe in hand-holding you through every step of this journey. Rest assured that we will be with you at every step. The process begins with consultations with the doctor and the team. You will be advised certain tests and based on your reports and overall assessment, you along-with the doctor and the team will decide on the procedure that will work the best. Before the surgery, you will be on a high protein diet for a minimum of one week. Prior to surgery you may also need to see other specialist like an endocrinologist, nephrologist, chest physician etc based on your medical history. It is advisable to get admitted on the evening before the day of surgery.

Expected weight loss after bariatric surgery

Bariatric surgery or weight loss surgery leads to massive amounts of weight loss. On an average after any of the bariatric operations most patients will lose about 65 to 75% of their excess weight. This could be less or more depending on multiple factors such as post-operative diet, efforts put in terms of exercise, follow up by the bariatric team, associated co-morbidities, drug intake etc. Surgery leads to a considerable improvement in the quality of life of the patient and most patients are able to maintain atleast 50% of excess weight loss at the end of 5 years post surgery which is much higher than any other form of weight loss.

Improvement in associated diseases

Bariatric surgery leads to a significant improvement in associated co-morbidities. Type 2 diabetes becomes better in 80 to 98% of patients. A significant number of patients do not need to take any medications for diabetes after the surgery. Ofcourse, this also depends on the duration of diabetes, c-peptide levels, age and BMI of the patient. High blood pressure becomes better in almost 70% of the patients. There is an overall 80% improvement in metabolic syndrome. Surgery also leads to a significant betterment in other co-morbidities such as PCOS, joint diseases, gout, obstructive sleep apnoea, COPD etc.

Post-operative schedule for follow up

Regular follow up is the key to success after bariatric surgery. After surgery, you have to follow up for 3 times in the first year with your reports and once every year thereafter. There are many changes pertaining to your lifestyle, dietary habits, exercise schedule etc that need constant support and counselling. It has been seen that patients who follow up regularly, tend to get better results.
