What is Bariatric Surgery?

Dr Maran who does Bariatric surgery in Chennai happens to be one of the top bariatric surgeon in Chennai. He explains that “Bar” in Greek means “weight” and “Iatr”, also in Greek means “treatment”. So as the name goes, bariatric literally means “Treatment for weight” or “Treatment for obesity”. Bariatric surgery is a treatment for people who are severe or very severely obese and are suffering from one or more comorbid conditions.

The human body best responds to proper diet and work out regimens. But morbidly obese people have constraints and can neither maintain a diet nor have ease in performing workouts. In other words, when people become extremely obese (BMI above 40) and also develop co-morbid conditions, it is not possible to manage their weight. Change in lifestyle and dieting are no more enough for them to sustain weight loss. Physical activities are almost impossible. The only scientifically available option before such individual is bariatric surgery also called weight loss surgery. This surgical approach gives more hope for the severely and very severely obese individuals

More About Bariatric Surgery

There are basically two principles in the field of bariatric or weight loss surgery. They are restriction and malabsorption.

The Principle of Restriction

Restrictive means physically restricting the size of the stomach. So restriction is making the stomach smaller. This results in stomach holding less volume of food. Also, the digestion process is slowed down because the surface area of the stomach has reduced. Gastric Banding and Gastric Balloon are restrictive bariatric surgery procedures.

The Principle of Restriction and Malabsorption

This involves restriction principles and along with it malabsorption too. When some parts of the digestive tract are surgically removed, the body loses the capacity to absorb the nutrients. This is called malabsorption. Gastric Bypass Roux-en-Y, Mini Bypass, Duodenal Switch, and Biliopancreatic Bypass are surgical procedures that employ both the principles of restriction and malabsorption.

 

Can all overweight and obese person undergo Bariatric Surgery?

Not really. For a person to undergo bariatric surgery, the bariatric surgeon would evaluate if it is absolutely necessary. Here are three important criteria a bariatric surgeon would consider before recommending an individual to undergo bariatric surgery.

  • Whether the person has a BMI (Body Mass Index) of 40 or more. In other words, if the patients are very severely obese or morbidly obese.
  • Have a lesser BMI of 35 or even slightly lesser (these still should fall under the category of moderately obese or severely obese) but have other medical conditions associated with obesity called co-morbid conditions.
  • Whether the person has tried all other methods to lose weight but is unsuccessful and is now prepared to undergo the surgery fully knowing what the procedure involves with its risks.

If you are an individual who seems to fit in any of the above categories and you are meeting with the bariatric surgeon you can, in turn, ask him few questions to get more clarity. Click here to know the ten questions you can ask your bariatric surgeon before weight loss surgery.

The above criteria may now induce an inquisition to know more about BMI and co-morbid medical conditions. Let us see them briefly here.

What is BMI or Body Mass Index?

BMI stands for Body Mass Index. It is a measurement where the body weight in kg is divided by the square of height in meters.

BMI = kg/(m)2

If BMI is greater than 25 and within 30, the person is overweight. If the BMI is between 30 and 35, the person is moderately obese. If the BMI is greater than 35 and within 40, the person is severely obese and if the BMI is beyond 40, then the person is very severely obese or morbidly obese.

What are co-morbid medical conditions?

Co-morbid medical conditions or co-morbidity is basically a very general term. If a primary disease is accompanied by additional diseases or disorders then those conditions are termed as co-morbid medical conditions, also referred to as co-morbidity.

The greatest co-morbid risk is the risk of acquiring type-2 diabetes. The other co-morbid conditions are High blood pressure, sleeping disorders like sleep apnea, stroke, fertility-related problems, osteoarthritis, etc. It should be kept in mind that these health issues affecting the morbidly obese persons need not necessarily happen only if an individual crosses a BMI of 40. It may happen to people who have crossed a BMI of 30 or 35 also. This is quite complex and it may be tagged to the genes, lifestyle associated stress, etc. The health issues affecting the morbidly obese patients' people are myriad.

How does weight reduction happens in any Bariatric Surgeries?

The weight reduction basically happens only in either of the two ways, namely, procedures restricting the quantity of food taken (restrictive) and second by procedures that are a combination of restrictive and mal-absorption, where mal-absorption is allowing the body to absorb less.

Generally, the restrictive bariatric procedures are recommended for people who overeat and the combination bariatric procedures are recommended for people whose severe or morbid obesity is due to the combination of diseases and other factors.

The different types of bariatric surgeries and how weight reduction happens

The various commonly done bariatric procedures are given below. In each, the principles of how weight reduction is achieved are given against each weight loss surgery types.

  • Intra Gastric Balloon – Restrictive
  • Gastric Banding – Restrictive
  • Gastric Sleeve also called Sleeve Gastrectomy – Restrictive
  • Gastric ByPass also called Roux-en-Y Gastric Bypass – Both Restrictive and Mal-Absorption
  • Mini Gastric ByPass also called Roux-en-Y Gastric Bypass – Both Restrictive and Mal-Absorption
  • Metabolic Surgery – Both Restrictive and Mal-Absorption
  • BPD (Bilio Pancreatic Diversion) and BPD/DS (Bilio Pancreatic Diversion with Duodenal Switch) – Both Restrictive and Mal-Absorption

Diet Before Undergoing a Bariatric Surgery

A bariatric surgeon normally recommends a pre-surgical diet regimen if you decide to undergo the surgery. In other surgeries, most surgeons advise to eat lean or skip your meal a few hours before the surgery. Well, it is a different story when it comes to any form of bariatric surgeries.

Why pre-surgical or pre-op diet for Bariatric Surgery?

  • Since the entire talk and action is about reducing the food intake, a pre-surgical diet becomes essential. This gives a signal to the body that things are going to come in a reduced quantity. This approach immensely reduces the risks after the bariatric surgery.
  • Not only that, the pre-surgical diet or the pre-op diet makes the laparoscopic bariatric surgery more effective. This pre-op diet makes the flogging liver firmer. It also makes the slippery fat found in the visceral region to shrink. These two prevent unnecessary bleeding during the surgery and hence the effectiveness of the surgery.
  • The diet helps bring the co-morbid condition under control before the surgery.
  • All these above factors contributed to reducing the recovery time after the surgery.

The primary aim of the pre-op diet is to reduce the weight and to give proper hydration to the body. This helps in making the liver firmer and reducing the visceral fat.

When to start Pre-Op Diet for bariatric surgery?

The patient should undergo a pre-op diet at least 2 weeks before the actual bariatric surgery date. This is recommended by the bariatric surgeon. So it is like prepping your body for the surgery.

The Actual Pre-Op Diet for Bariatric  Surgery

  • Water – Helps to maintain the fluid content of the body.
  • Diluted juices of fruits and vegetables – this provides you with essential minerals, salts and vitamins, and energy
  • Soups – Soups made of mashed chicken can provide necessary protein and essential fat to the body.
  • Protein Shake – Your bariatric surgeon recommends the best protein shake. Protein shakes are necessary to supply the body with the essential protein needs. This is required for weight loss.
  • Milk – Milk not only gives protein but also supplies the essential fat to the body.
  • Calcium and Multivitamin Tablets – Your bariatric surgeon recommends the necessary calcium and vitamin supplements. He recommends based on the requirement of your body.

Diet after Bariatric Surgery

Undergoing bariatric surgery does not give a passport to eat anything and everything. So what should a person who has undergone bariatric surgery eat as a continuing practice and how should they eat?

Positive Outcomes of Bariatric Surgery

After bariatric surgery, the stomach capacity and its churning action are greatly reduced. In Gastric By-pass bariatric surgery, the digestion happens in the small intestine and not in the stomach which is a radical alteration in the digestive process. The surgeries that involve malabsorption, the requirement of micronutrients is markedly increased. These are the general reasons why diet plays a vital role after your bariatric surgery.

Diet Immediately after Bariatric Surgery

Your bariatric surgeon along with the nutritionist would typically take you through the diet that you may have to strictly adhere to immediately after your bariatric surgery. The diet would be comprised of lighter soup, fruit juices, protein shake, mashed vegetables, milk. Along comes calcium and vitamin tablets which you have to take for life.

Diet to be followed regularly over the course – What to eat?

Your diet after your recovery from bariatric surgery or long-term bariatric diet would typically consist of a simple goal. The diet goal would be to eat healthy, more protein intake, drink more water and fluids like fruit juices, and snack healthy if you want to. So anything like milk, soup, vegetables, fruits, lean meat, all in smaller proportions can be consumed along with the very essential bariatric vitamins.

Apart from what to eat after bariatric surgery, Dr Maran who has done many Bariatric Surgery in Chennai also talks about "How to eat after a Bariatric Surgery".

Non-cosmetic Nature of Bariatric Surgery

Unlike liposuction, Bariatric surgery is not a cosmetic surgery procedure. It is more therapeutic because it gives relief from co-morbid conditions. Bariatric surgery does not involve any sucking out of lipocytes or fat cells. Liposuction surgical procedures are completely different and bariatric surgery cannot be confused with them.
