Treatments & Procedures

The study of bariatrics is a highly advanced and sophisticated discipline of medicine dealing with a wide range of surgical procedures, aimed at losing weight by making necessary changes in the human digestive system.

These complex surgeries handled by bariatric surgeons are usually divided into restrictive, malabsorptive and hybrid (a combination of restrictive and malabsorptive). Though the classifications were done long ago, these standard care procedures are precisely followed for achieving the desired results. While all the bariatric procedures primarily cause hormonal effect and aid in losing weight, certain procedures for the remission of diabetes is recommended only for those patients with a BMI that falls in the class 1 obesity range.

  1. Lap Adjustable Gastric Banding (Restrictive)

    Lap Adjustable Gastric Banding is a popular and widely performed bariatric surgical procedure under which an adjustable band is placed around the upper most part of the stomach separating the stomach into a small and large portion. Intended at decreasing the consumption of food, this silicone band usually known as lap-band, A band or LAGB slows down the amount of food consumed in the single go, providing a sense of satiety. The patient who had undergone Lap Adjustable Gastric Banding would be able to considerably reduce the amount of food and fluid intake and avoid sudden hunger pangs, thus leading to weight loss.

    Advantages: 

    It is a reversible procedure

    The patient will feel better digestion of food and it won’t obstruct the absorption of nutrients

  2. Sleeve Gastrectomy (Restrictive)

    Widely known as Vertical Sleeve Gastrectomy, Sleeve Gastrectomy is an invasive weight-loss procedure in which the stomach is reduced to about 25% of its original size by removing a large portion of the it, along the greater curvature. During the procedure the expert surgeon would also remove the ghrelin hormone secreting fundus, responsible for appetite, thus suppressing hunger as well. Typically done as a laparoscopic procedure, the patient would recover much faster and would witness faster results.

    Advantages: 

    Excellent weight loss at one year

    Great appetite suppression and restricts hunger pangs completely

    Low risk of peptic ulcer

    No vitamin or drug malabsorption

  3. Banded Sleeve Gastrectomy (Restrictive)

    Under Banded Sleeve Gastrectomy, a loose band is placed over the completed sleeve gastrectomy tube to prevent sleeve dilation and to improve food restriction. It ensures that the restrictive effect of sleeve is maintained in the longer run and avoid weight gain.

    Advantages:

    Prevents weight regain

    Sustainable weight loss and visible results

  4. Roux-En-Y Gastric Bypass (Combined – Restrictive/Malabsorptive)

    Roux-En-Y Gastric Bypass is a laparoscopic bariatric procedure in which a small pouch of stomach is created by stapling off the upper portion of the stomach. After that the expert surgeon would attach the pouch directly to a part of small intestine called as Roux limb forming it into a ‘Y’ shape. The idea behind this procedure is to bypass the rest of the stomach and also upper portion of small intestine to limit the absorption of fat and calories in the foods consumed, thus leading to weight loss.

    Advantages:

    About 95 % of co-existing health problems including type 2 diabetes, high BP, high cholesterol, sleep apnoea, depression, back pain was improved or resolved. Also, the risk of developing heart attack and stroke is significantly lowered.

    Highly sustainable weight loss.

    Maintenance of weight in the longer run is easier

  5. Banded Gastric Bypass (combined – Restrictive/Malabsorptive)

    Banded Gastric Bypass is a combination of both restriction and malabsorption in which a loose band is applied over the completed pouch in Gastric Bypass. The restrictive procedure triggers weight loss while the malabsorption bypasses the part of small intestine by diverting biliopancreatic secretions limiting the absorption of fat and calories. This procedure also prevents pouch dilatation that can happen later thus preventing weight regain.

    Advantages:

    This procedure is similar to standard gastric bypass.

    Weight regain can be avoided

  6. Mini gastric Bypass/ One Anastomosis Gastric Bypass (Combined – Restrictive/Malabsorptive)

    Mini Gastric Bypass is a technical modification of the standard gastric bypass with the same results. The surgery is simpler compared to the Roux-en-y Gastric Bypass and hence less time consuming.

    Advantages :

    Triggers weight loss

    Reversible procedure

  7. Bilio Pancreatic Diversion With Duodenal Switch (Malabsorptive)

    Bilio Pancreatic Diversion With Duodenal Switch is done in two steps, but in a single procedure. In the first stage, a sleeve gastrectomy is performed and 80 per cent of the stomach is removed. And in the second step, the remaining stomach that looks like a small tube bypasses the upper part of the small intestine and the end portion of small intestine then gets connected to the duodenum near the stomach.

    Advantages:

    Provides positive results and faster weight loss

    Best outcome for patients suffering from Type 2 Diabetes Mellitus and high levels of cholesterol.

    Surgeries For Diabetics:

    Diabetics is a chronic disorder affecting millions of people across the globe annually. The high levels of blood sugars, if not controlled can cause major health complications including heart attack, cardiovascular diseases and can compromise the function of other vital organs. The bariatric procedures are a boon to those diabetics also combating obesity. Several studies reveal that weight loss after these procedures resulted in remission of this metabolic and lifestyle disorder for up to 10 years.

  8. Short duodenal switch / Loop duodenal switch (combined – Restrictive/Malabsorptive)

    Short duodenal switch / Loop duodenal switch is a technical modification of the standard BPD wherein the malabsorptive component is less, thus resulting in regulated blood sugars. There is a single anastomosis making the surgery less time consuming.

    Advantages :

    Excellent resolution of type 2 Diabetes.

    Good weight loss in obese patients

  9. Ileal interposition 

    Ileal Interposition is not just a bariatric procedure but is also widely recommended for those suffering from type-2 diabetes. Under this procedure, a long segment of the last potion of small intestine (ileum) is cut and joined very close to the stomach. Undigested food now first enters ileum to stimulate gut hormones called GLP-1 which acts along with insulin to reduce blood sugar.

    Advantages:

    Can also be performed on non-obese diabetic patient

    Endoscopic Procedures:

    Endoscopic procedures are an in-thing in the field of bariatrics and metabolic surgeries. The procedures which are very precise are less time consuming and the patient gets discharged the same day.

  10. Intra Gastric Balloon

    Intra Gastric Balloon is done by placing an adjustable balloon through an endoscope and inflated with saline inside the stomach. It is left in the stomach for 6 months to 1 year till weight loss happens. The balloon provides the feeling of satiety and controls the hunger pangs.

    Advantages :

    Day care procedure – Can be discharged same day

    Non-Surgical procedure

  11. Endoscopic Sleeve Gastroplasty

    Using an endoscope, the size of the stomach is reduced. This relatively newer procedure is gaining popularity owing to its both short-term and long-term benefits.

    Advantages :

    Nonsurgical Procedure

    Triggers weight loss

FAQs:

If you are planning for a bariatric surgery, it’s time to learn in detail about the procedures, effects, complications if any etc. Here are most frequently asked questions and the answers.

What Are The Parameters To Know If I Am Fat/Obese?

For every individual person, the ideal body weight depends on his/ her height. To know it exactly, doctors calculate the Body Mass Index (BMI) taking their weight and height. BMI of a normal person ranges from 18.5 to 24.9 Kg/m2

Being Fatter Is Healthier. Why Do I Worry?

That is quite a myth! Being fat is not being healthier. Obesity is also considered as a malnutrition and it can lead to other complications like Type 2 diabetes, high blood pressure, high cholesterol, increased risk of heart attack and stroke, joint pains, sleep apnoea, fatty liver causing liver failure, gall stones, menstrual disturbances in women, PCOD/ infertility issues, Depression and many other problems.

Obese people are at increased risk of developing various cancers including food pipe (oesophagus), stomach, liver, pancreas, colon, rectum, kidney, ovary, breast and uterus. By reducing weight the risk is significantly reduced.

How To Check My BMI ?

BMI refers to Body Mass Index. It is derived by dividing the body weight in Kg by the height in m2.

Ex: A person with height 170 cm, weight is 120 kg

BMI = 120/ 1.7 x 1.7

= 120/ 2.89

= 41.52 kg/m2

What Is The Normal BMI Range?

World health organisation has classified BMI as follows

18.5 to 24.9 – normal weight

25 – 29.9 – overweight

30 – 34.9 – class 1 or mild obesity

35- 39.9 – class 2 or severe obesity

40 – 49.9 – morbid obesity

>50 – super obese

>70 – mega obese

Does The Same Criteria Suit Me, As Well?

If you are an Indian or from Asia Pacific region, the BMI criteria is as follows

18.5 to 22.9 – normal

23 – 27.49 – overweight

27.5 - 32.49 – class 1 or mild obesity

32.5 – 37.49 – class 2 or severe obesity

37.5 or more – morbid obesity

Why Is There A Separate Criterion For Asians?

This is because, genetically, Asians are prone to have more visceral (internal) fat compared to the Western population. The internal fat is more dangerous and leads to all the ill effects of obesity. Considering this, the criteria is modified to address the problem at the right time.

I Have Been A Following Strict Diet For Quite But Still Unable To Lose Weight! Why ?

Our body weight is determined by our brain called “set point theory”. Beyond a certain weight, body will resist our efforts to lose weight. The body’s metabolism will also be on a lower side. So crash diet or fasting will not be useful to reduce the required amount of weight.

What If These Options Fail?

Diet, activity, lifestyle modifications are the first line of treatment for excess weight. Additionally, some medications may be useful. However, if these fail then Bariatric surgery will give the best result.

I Prefer Medicines To Surgery ….

Medicines can reduce maximum 10% of excess body weight if taken continuously. Once stopped, the weight regain happens. So, for overweight or mild obesity it will be a good option. But for severe obesity and morbid obesity, it is not cost effective. The desired target weight can’t be achieved and also the comorbidity resolution does not happen. Thus, medicines can’t be the answer for all patients.

What Exactly Is Bariatric Surgery?

‘Baros’ in Greek means weight.

Bariatric is derived from the Greek word Baros meaning reducing weight.

It is minimally invasive, laparoscopic (key hole) procedure which increases the body metabolism by secreting gut hormones called ‘incretins’ which acts in the brain to reset the weight. This is achieved by modifying the stomach size and the food passage in the intestine.

I Have Heard Of Liposuction. Is It Same As Bariatric Surgery?

A big NO!

Liposuction is a procedure where fat beneath the skin is sucked out using a special technique. Maximum of 5 -8 kg of fat can be removed. It is purely a cosmetic procedure. There is no weight loss involved in this and there is no improvement in comorbidities.

On the other hand, Bariatric procedure is a keyhole procedure which stimulates body metabolism to lose weight. Here no fat is removed. Body inherently burns all the excess fat over a period of few months.

How Do I Know if I am Fit For Bariatric Surgery?
