Obesity (Bariatric) Surgery



Obesity is a life-long, progressive, life-threatening condition marked by excess body fat, which can significantly reduce life expectancy. When weight increases to an extreme level, it is called morbid obesity, and is a chronic condition with numerous medical, psychological, social and economic consequences.

The more obese you are, the more likely you are to have health problems. People who have struggled for many years with the illnesses and discomforts related to severe obesity often give up hope. They know what it is like to persevere time and again with diets and programs that fail to deliver long-term results. Nonetheless, giving up is not an option. Their lives depend on successfully treating obesity and maintaining a healthy weight throughout life. If you are someone for whom non-surgical procedures have failed to provide sustained weight loss, you can be evaluated for, and if appropriate, undergo lifesaving bariatric surgery. In cases of severe obesity, bariatric surgery is the only proven method of achieving long-term weight control.

    Frequently asked Questions about Obesity treatment

    What is the medical treatment of Obesity?

    Adequate diet and exercise are the key components. A recommended balanced diet should provide 1200-2000 Calories a day depending upon the person's lifestyle. A diet restriction of 500Cal/day is expected to cause a wt loss of approx 1lb/week. A regular exercise pattern is of immense importance. A duration of 30-45 minutes per day, at least 3-5 days/week is recommended by most. Even if you are planning for surgery, an exercise plan is a must. Medicines for obesity have not been very popular because of their undesired effects. At present, the only FDA approved drug is Orlistat. Even this is not free of side effects and causes only upto 10% weight loss in six months, most of which is regained after stopping the drug.

    What are the benefits of surgical treatment of obesity?

    Various studies all over the world have proved that surgery is the most desirable and durable treatment option for morbid obesity. With the current surgical procedures, a loss of 68-78% excess body weight is lost. The most dramatic loss is in the first six months. The procedures like Roux-en-Y Gastric Bypass and Sleeve gastrectomy reduce food intake because of early filling as well as decreased hunger. This avoids 'starvation' to get slimmer.

    Does Obesity Surgery resolve diseases like diabetes, hypertension, sleep apnea etc.?

    Yes. Bariatric Surgery has shown to cure diabetes in 83% of patients and reduce the dose of Insulin & OHA in 17%. The control of hypertension also becomes better. Obstructive sleep apnea patients show a remarkable improvement.

    How Does Obesity/Bariatric Surgery Work?

    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 behaviors and regular physical activity.

    If bariatric surgery is the right choice for you, your surgeon will discuss with you the procedures offered at and will explain which would achieve the best outcomes for your individual circumstance.

    Am I a candidate for surgical treatment for obesity?

    If you are an Indian/Asian and have BMI of 37.5 or more, you are a candidate for Bariatric Surgery, as it is the only durable option at this stage. If you have Hypertension / Diabetes / Obstructive Sleep Apnea / Osteoarthiritis knee or have any other obesity related diseases, surgery is recommended at a BMI of 32.5 or more.

    It is a serious undertaking, not a cosmetic procedure. Anyone thinking about undergoing this type of operation should understand that the surgery will cause a reduction in the number of calories you may consume, and you must commit to lifestyle and dietary changes to derive maximum benefit from the procedure. The surgery in not a cure it is only a tool. Success is possible only with your full cooperation and commitment to behavioral change and medical follow-up, which must be carried out for the rest of your life.

    What are the risks that I need to be aware of?

    All surgical procedures carry risks, even more so when a patient is obese. Different procedures involve different risks, and depending upon your individual circumstances, your risks may be higher or lower than average. Keep in mind that in a hospital with a team of doctors from various specialities and huge experience in bariatric surgery, the complication and mortality rates will be lower. Your surgeon will discuss potential risks of surgery with you so you can make an educated and informed decision.

    Types of Bariatric Surgery:

    Surgical procedures done at Sudha Hospital are
    a) Laparoscopic Sleeve Gastrectomy
    b) Laparoscopic Roux-en-Y Gastric Bypass
    c) Laparoscopic Adjustable Gastric banding
    d) Endoscopic procedure Intra-Gastric Balloon
    With the advent of latest technology and skills, patients now get a minimally invasive advantage of key hole surgery leading to fast recovery, less pain, better cosmesis, small scars and early return to work.

    Laparoscopic Sleeve Gastrectomy (LSG)

    In this restrictive procedure, the capacity of stomach is reduced to approximately 100ml, so the patient feels full early during a meal. It also shifts the hormonal balance so he/she feels less hungry between meals.

    In LSG, the stomach is divided along the greater curvature to create a 60-100 ml sleeve of stomach using endoscopic staplers. The staple line is always oversewn for extra security and safety to prevent any leak or bleed from staple line. The integrity of the pouch is checked using per-operative gastroscopy. The excised portion of stomach is removed in a plastic bag. A small abdominal drain is usually left which is taken out after 48-72 hours.


    In patients who underwent LSG, there is a weight loss to the tune of 70-95% of excess body weight. Resolution of Diabetes occurred in 80% and resolution of HTN occurred in 70%.

    Laparoscopic Roux-n-Y Gastric Bypass (LRYGB)



    It is also an effective procedure for resolution of diabetes, sleep apnea and control of hypertension. In this, a small gastric pouch of 15-20ml is created, which a reduction of food intake at a time. The intestinal architecture is then changed so that a large portion (175-250cm) of small intestine is bypassed, before the digestion and absorption of food starts. This results in malabsorption of food, and subsequent drastic weight loss. In the end, the integrity of pouch is checked using per-operative gastroscopy. A small abdominal drain is usually left which is taken out after 48-96 hours

    Laparoscopic Adjustable Gastric Banding (LAGB)



    In laparoscopic adjustable gastric band an inflatable silicone device is placed around the top of your stomach resulting in slow consumption of food and thus reduces the amount of food consumed at one time.
    So when you eat, food pushes the wall of the stomach and sends signals to the brain to curb your appetite. Benefits:

  • The band can be re-adjusted or removed at any time.
  • There is no removal of any part of stomach or intestine resulting in complete absorption of food.
  • Resolves the other medical complications associated with obesity as diabetes, joint pain etc.
  • Post-surgical recovery is very fast
  • Endoscopic procedure Intra-Gastric Balloon



    Intragastric balloon is a relatively new weight loss device, for patients who are a little overweight and want a helping hand to starting a healthier way of living.

    It is a soft, silicone balloon, about the size of a mango, which is inserted into the stomach and remains inside for 6 months. The balloon acts a little like a valve and most patients find they have a greatly reduced appetite and can lose a lot of weight quite quickly (over 2 to 3 months). The average weight loss is around 15kg.

    Considering weight loss surgery?

    Obesity is a chronic and progressive disease that can affect multiple organs in the body. People with clinically severe obesity are at a great medical risk of disability or premature death. In fact, thousands die prematurely each year of obesity related complications or co-morbidities. Obesity affects an individual both medically (diabetes- Type-2, HTN, high cholesterol, joints pain, lack of sleep {sleep apnea}, urinary stress incontinence and severe acid reflex) and emotionally (low self-esteem, lack of confidence). Weight loss/ bariatric surgery can not only reduce these complications but even reverse them.

    Is Bariatric surgery right for me?

    Weight loss surgery helps people with extreme obesity to lose weight. It may be an option if your BMI is 32.5kg/m2 or more and cannot lose weight through diet and exercise or have serious health such as hypertension, impaired glucose tolerance, diabetes mellitus, hyperlipidemia, and obstructive sleep apnea caused by obesity.

    Answers to the following questions may help YOU decide whether weight-loss surgery is right for you.

  • Unlikely to lose weight or keep it off over the long term using other methods?
  • Aware of the risks and benefits of surgery?
  • Ready to lose weight and improve his or her health?
  • Aware of how life may change after the surgery? (For example, patients need to adjust to side effects, such as the need to chew food well and the loss of ability to eat large meals.)
  • Committed to lifelong healthy eating and physical activity, medical follow-up, and the need to take extra vitamins and minerals?


  • What do I expect after surgery?

    After the surgery, the patient is kept overnight under close observation. Next day, the patient is started on a clear liquid diet after doing a contrast X-ray study, and shifted to room. He/she is encouraged to walk and do all routine activities.

    He/she is discharged on the third or fourth day of surgery depending on the comfort of the patient and amount of oral intake. A detailed and properly explained discharge summary is given to the patient along with a diet chart.

    First follow-up visit is after seven days and then at 1 month, 3 months, 6 months, 1 year and yearly thereafter. The patients are encouraged to exercise and do maximum physical activity. One can expect an excess body weight loss to the tune of 70-95 % depending on the procedure and compliance of the patient with the instructions. A long term dietary supplementation is usually required with RYGB but not so with LSG.
